    Hello,

    since using the latest version from asset store (2.0.11) when reading GLB from file I have multiple materials for one renderer and transparency / alpa is supported, too. That is very nice, in v1.87 that did not work.

    But I habe a strange problem: it works in editor, but in my build it does not. Do I need to incude some shader to the build or something like this?

    Thanks a lot!

    Hello,

    since the upgrad from TriLib 1.8.7 to 2.0.14 when reading a glb file each renderer can have multiple colors and alpha / transparency is supported, too, thants great!

    But it does only work in the editor...

    When I create Windows Standalone Build my GLB glass doors are fully white and opaque, in the editor they are transparent...

    I tried to add all TriLib shaders to my project settings, but does not seem to help.

    Any help please?

    I solved the transparency problem by using the standard shader everywhere and set it's Mode (opaque, transparent) by script when needed.

    But I found another strange probem, I guess it is new after upgrading from TriLib 1.87 to 2.0.11:

    My loaded GLB files all appear mirrored! I am using this workaround now then it is okay:

    Code (CSharp):
    1.       /// <summary>
    2.         /// Done loading model, hide placeholder (bounding box) and progress and set collider
    3.         /// </summary>
    4.         private void OnModelLoad(AssetLoaderContext obj)
    5.         {
    6.             try
    7.             {
    8.                 GameObject loadedGameObject = obj.RootGameObject;
    9.                 loadedGameObject.transform.localScale = new Vector3(-1, 1, 1);
    Could it be a bug in the GLB loader?

    Thanks!

    Hi!
    You should provide the inner model file extension as an argument since TriLib can't guess the model file format from the URL. So if you're downloading an FBX file, you must pass "fbx" at the AssetDownloader "fileExtension" argument.

    It is possible!
    I found a few gltf files producing wrong rotation values but the next TriLib update has some matrix manipulation fixes which could fix your issues.

    Hi!
    TriLib will automatically include all needed shader variants in your output project. You could try adding a hidden object to your scene using the TriLib/Standard material to make sure Unity is including it in the build. Please tell me if it works, so we will know if Unity is adding the material to the output project.

    Hi!

    I want to load a .fbx file that is not a .zip file and a .png or .jpg texture separately.

    In that case, we should be able to do it using ExternalDataMapper and TextureMapper, but I don't know how to use these two.

    Below is the code I tried:

    Code (CSharp):
    1. using System.Collections;
    2. using System.Collections.Generic;
    3. using UnityEngine;
    4. using TriLibCore;
    5. using TriLibCore.General;
    6.  
    7. public class SyncLoad : MonoBehaviour
    8. {
    9.  
    10.     private void OnError(IContextualizedError contextualizedError)
    11.     {
    12.         Debug.Log("OnError");  
    13.     }
    14.  
    15.     private void OnProgress(AssetLoaderContext assetLoaderContext, float progress)
    16.     {
    17.         Debug.Log("OnProgress");  
    18.  
    19.     }
    20.  
    21.     private void OnMaterialsLoad(AssetLoaderContext assetLoaderContext)
    22.     {
    23.         Debug.Log("OnMaterialsLoad");  
    24.     }
    25.  
    26.     private void OnLoad(AssetLoaderContext assetLoaderContext)
    27.     {
    28.         Debug.Log("OnLoad");  
    29.     }
    30.  
    31.     void Start()
    32.     {
    33.         var assetLoaderOptions = AssetLoader.CreateDefaultLoaderOptions();
    34.         assetLoaderOptions.ExternalDataMapper = ScriptableObject.CreateInstance<ExternalDataMapperSample>();
    35.         assetLoaderOptions.TextureMapper = ScriptableObject.CreateInstance<TextureMapperSample>();
    36.         var modelPath = "/Users/mac/Downloads/testObj.fbx";
    37.         AssetLoader.LoadModelFromStream(File.OpenRead(modelPath), modelPath, null, OnLoad, OnMaterialsLoad, OnProgress, OnError, null, assetLoaderOptions);
    38.     }
    39. }
    40.  
    41. public class ExternalDataMapperSample : ExternalDataMapper
    42. {
    43.     public override Stream Map(AssetLoaderContext assetLoaderContext, string originalFilename, out string finalPath)
    44.     {
    45.         finalPath = $"{assetLoaderContext.BasePath}/{FileUtils.GetFilename(originalFilename)}";
    46.         if (File.Exists(finalPath))
    47.         {
    48.             Debug.Log($"Found external file at: {finalPath}");
    49.             return File.OpenRead(finalPath);
    50.         }
    51.         throw new Exception($"File {originalFilename} not found.");
    52.     }
    53. }
    54.  
    55. public class TextureMapperSample : TextureMapper
    56. {
    57.     public override TextureLoadingContext Map(AssetLoaderContext assetLoaderContext, ITexture texture)
    58.     {
    59.         var finalPath = $"{assetLoaderContext.BasePath}/{FileUtils.GetFilename(texture.Filename)}";
    60.         if (File.Exists(finalPath))
    61.         {
    62.             var textureLoadingContext = new TextureLoadingContext
    63.             {
    64.                 Context = assetLoaderContext,
    65.                 Stream = File.OpenRead(finalPath),
    66.                 Texture = texture
    67.             };
    68.             Debug.Log($"Found texture at: {finalPath}");
    69.             return textureLoadingContext;
    70.         }
    71.         throw new Exception($"Texture {texture.Filename} not found.");
    72.     }
    73. }
    However, I get the following error:

    Code (CSharp):
    1. Assets/SyncLoad.cs(55,36): error CS0246: The type or namespace name 'TextureMapper' could not be found (are you missing a using directive or an assembly reference?)
    2. Assets/SyncLoad.cs(57,83): error CS0246: The type or namespace name 'ITexture' could not be found (are you missing a using directive or an assembly reference?)
    3. Assets/SyncLoad.cs(57,40): error CS0115: 'TextureMapperSample.Map(AssetLoaderContext, ITexture)': no suitable method found to override
    4. Assets/SyncLoad.cs(41,41): error CS0246: The type or namespace name 'ExternalDataMapper' could not be found (are you missing a using directive or an assembly reference?)
    5. Assets/SyncLoad.cs(43,18): error CS0246: The type or namespace name 'Stream' could not be found (are you missing a using directive or an assembly reference?)
    6. Assets/SyncLoad.cs(43,25): error CS0115: 'ExternalDataMapperSample.Map(AssetLoaderContext, string, out string)': no suitable method found to override
    What am I missing in my code?
    Do I need to import anything other than TriLibCore and TriLibCore.General?

    We're having an issue where the first time any model is loaded, it has no materials (turns up pink).

    - it only happens in our game, I tried to make a simple repro project and was not able to.
    - it only happens in a build (Windows standalone), it does not happen in the editor
    - I've verified that AssetUnloader.OnDestroy is not being called
    - I'm pretty sure it happens with any model type, but definitely .obj
    - It isn't 100% repro, so maybe there is some race condition? But it seems to happen the majority of the time
    - Loading the same model a second time works fine - it's just the first time it is loaded

    Unity version: 2019.4.14

    Can you think of anything that might cause this, or what I can do to help diagnose it? Is there a way to turn on more detailed logging for TriLib2? I don't see anything unusual in the player.log.

    Where are your textures located? I could provide a quick sample if you show me the structures/streams/classes containing the texture data.

    Hi!

    TriLib 2.0.12 is waiting approval on the Asset Store. I have fixed some Material Mapper assignment issues which may fix your issues as well.

    I will check out, never heard about these texture formats.
    One thing that I will probably add to the next TriLib update (2.0.13) is DDS textures support.

    TriLib 2.0.12 is pending approval on Asset Store, but I want to show an useful new feature I've added.
    Under Project Settings/TriLib area, we have a few more options now:

    The first section allows users to disable specific file formats reader which are not necessary for the project.

    The second section allows users to enable material mappers according to the project rendering pipeline. Custom material mappers following the template used in any of these mappers will be visible on this list as well.

    The third section allows users to enable advanced and experimental features.

    The settings are saved per-project on the TriLibSettings asset.

    Hi,
    I just purchased Trilib 2 and am having some trouble.

    I have a very specific use case where the user can put models in a folder, then I save the path to that folder and load all models in it on the scene load. Because my application is a VR app, I want to avoid opening a file dialog.

    Here's my code:

    Code (CSharp):
    1.  var filesInFolder = Directory.EnumerateFiles(modelPath, "*.*", SearchOption.AllDirectories)
    2.             .Where(s => s.EndsWith(".fbx") || s.EndsWith(".obj") || s.EndsWith(".zip") || s.EndsWith(".gltf")).ToArray();
    3.  
    4.         for (int i = 0; i < filesInFolder.Length; i++)
    5.         {
    6.             var assetLoaderOptions = AssetLoader.CreateDefaultLoaderOptions();
    7.             AssetLoader.LoadModelFromFile(filesInFolder[i], null, OnMaterialsLoad, null, OnError, null, assetLoaderOptions);
    8.             Debug.Log(filesInFolder[i]);
    9.         }
    10.         Debug.Log(filesInFolder);
    11.     }
    12.     private void OnMaterialsLoad(AssetLoaderContext obj)
    13.     {
    14.         var loadedObject = obj.RootGameObject;
    15.  
    16.         if (loadedObject.GetComponent<SpawnableObject>() == null)
    17.         {
    18.             SpawnableObject SO = loadedObject.AddComponent<SpawnableObject>();
    19.         }
    20.         fullObjectLibrary.Add(loadedObject);
    21.         propLibrary.Add(loadedObject);
    22.         Debug.Log("ADDED CUSTOM MODEL TO DATABASE!");
    23.         loadedObject.SetActive(false);
    24.     }
    1) None of my materials are going through. The mesh just looks pink, even though I am doing everything correctly.
    2) When I set an imported model as inactive, then active again, all the meshes are missing and therefore invisible
    3) The same thing happens when I clone (Instantiate) an imported model -- All meshes are missing.

    Any and all help would be appreciated! Thanks!

    Hi,Ricardo
    Thank you for your reply!

    The path for my model is below.
    "/Users/mac/Downloads/testObj.fbx"

    And my texture folder path is below.
    "/Users/mac/Downloads/textures"

    And my texture path is below.
    "/Users/mac/Downloads/textures/textureA.png"
    "/Users/mac/Downloads/textures/textureB.png"

    Please tell me how to load textures correctly.

    I'm using URP, Trilib 2.0.12 (went live on Dec 28?), Unity 2020.2.1f1.

    The TriLib I got from the package manager do NOT include the settings you screenshotted above, only TriLibCore's reader settings. To troubleshoot, I deleted Trilib and redownloaded but it appears 2.0.12 is actually 2.0.11? The TriLibVersion.txt file reports it as 2.0.11. Could this be a problem with the Asset Store?

    Back to my main problem:
    I have the URP material mapper in my asset loader options and hand that to the loader in code, but no materials are created at runtime, even though console reports success with no errors. Even the included samples do not create materials (I modified the sample's assetLoaderOption field to include one with a URP mapper). Is it a known issue?

    Otherwise this is such an improvement over the last version, I'm very happy with your refactoring and changes so far!

    Could you please re-download the package?
    I've tested it here and I'm getting the right version from the store:

    Thank you for the quick reply! It was totally a problem with the asset store. I had to delete the .unitypackage stored in %appdata% and redownload. I got the right copy now.

    Hello- happy 1.x user just upgraded to 2.x :)

    Starting a new prototype where I'm trying to import .fbx character models from Daz Studio. I can import them with the avatar loader sample but the models come in twisted into knots.

    Is it possible to import rigged fbx models from Daz? If so what settings do you recommend? Thank you.

    TriLib 1.9x users: I have updated the GitHub repositories with fixes, included an iOS bitcode workflow, and added a new repository containing the stb-image libraries and make-files.

    I've already invited all collaborators to this new repository.

    If you own TriLib 1.9x and want to join the repositories, please e-mail me at contato@ricardoreis.net

    Hello,

    I am using PC standalone only for my build.

    I added TriLib 2 with the package manager, after that I deleted the Samples and HDRP folders.

    Can you give me a hint what else to delete to get my Build a bit smaller? There are so many DLLs maybe not all of them are needed for PC standalone.

    Thanks a lot!

    You can disable readers you won't use on the Project Settings/TriLib menu. After that, you can restart Unity and delete the DLLs from the readers you removed (eg: TriLibCore.obj.dll).
    Besides that and removing the folders from the rendering pipelines you won't use, I can't see anything else you could remove.

    Edit: There are some issues in the readers' selection area which I'm fixing now.

    Hello Ricardo,
    After I updated trilib 2 to the latest version the error below is always occurring.
    I'm using the latest version in Unity 2020.2.1 with HDRP.
    Already reinstalled and did not work.

    Recursive Serialization is not supported. You can't dereference a PPtr while loading. (Constructors of C# classes may not load objects either. See stacktrace.)

    Hi Ricardo! Congratulations, it's getting better and better !!
    I noticed a small crash in version 2.0.12b (asset store). It seems that every 1s there is some heavier processing that makes the screen reduce FPS, or even a small crash.
    Just reporting! Thanks!

    Oi Ricardo! Parabéns, está ficando cada vez mais aprimorado!!
    Eu percebi um pequeno travamento na versão 2.0.12b (asset store). Parece que a cada 1s há algum processamento mais pesado que faz a tela reduzir o FPS, ou até mesmo uma pequena travada.
    Apenas reportando! Obrigado!

    Is this while loading the model or after the model has been loaded?

    After the model has been loaded.
    In a response on Twitter, Marek Stój (@MarekStoj) told me that I could disable GCHelpers.
    What is the use of Garbage Collector every 1s?
    I tried to disable GCHelpers in three attempts:
    1 - Assigning the value false in ForceGCCollectionWhileLoading;
    2 - Deactivating by intance;
    3 - Commenting on an excerpt of the function that disables GCHelpers.

    The one that worked was attempt 3.
    What can I be doing wrong?

    Thanks Rick!

    Hi!

    The GC helper's behavior is working right at my tests, but I will surely test the above issue before the next update.
    Sorry about the delay. I'm finishing the mesh loading refactoring.

    Sorry about the delay guys.
    Next update will be ready tomorrow (should take some days to be accepted on Asset Store too).

    Hi,
    I got an error when I tried the AssetViewer example scene on Unity2020.2.1f1 and MacOS catalina.
    FilePicker worked in Unity Editor and if I select the model, it works to load model.
    But if I click the cancel button of FilePicking dialog, it occurs the following error.

    Code (CSharp):
    1. ArgumentException: Path is empty
    2. System.IO.FileStream..ctor (System.String path, System.IO.FileMode mode, System.IO.FileAccess access, System.IO.FileShare share, System.Int32 bufferSize, System.Boolean anonymous, System.IO.FileOptions options) (at <9577ac7a62ef43179789031239ba8798>:0)
    3. System.IO.FileStream..ctor (System.String path, System.IO.FileMode mode, System.IO.FileAccess access, System.IO.FileShare share) (at <9577ac7a62ef43179789031239ba8798>:0)
    4. (wrapper remoting-invoke-with-check) System.IO.FileStream..ctor(string,System.IO.FileMode,System.IO.FileAccess,System.IO.FileShare)
    5. System.IO.File.OpenRead (System.String path) (at <9577ac7a62ef43179789031239ba8798>:0)
    6. TriLibCore.SFB.ItemWithStream.OpenStream () (at Assets/TriLib/TriLibStandaloneFileBrowser/StandaloneFileBrowser/ItemWithStream.cs:27)
    7. TriLibCore.AssetLoaderFilePicker+<DoHandleFileLoading>d__13.MoveNext () (at Assets/TriLib/TriLibStandaloneFileBrowser/StandaloneFileBrowser/TriLib/AssetLoaderFilePicker.cs:94)
    8. UnityEngine.SetupCoroutine.InvokeMoveNext (System.Collections.IEnumerator enumerator, System.IntPtr returnValueAddress) (at /Users/bokken/buildslave/unity/build/Runtime/Export/Scripting/Coroutines.cs:17)
    9. UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&) (at /Users/bokken/buildslave/unity/build/Modules/IMGUI/GUIUtility.cs:189)
    On Windows, this error never happens and everything works well.

    Also, when I clicked the cancel button of LoadModelURL dialog, the unity editor crashed.

    -Another issue.
    Filepicker works only in unity editor on mac OS.
    MacOS standalone build doesn't work at all for filepicker.
    It doesn't even popup the filepicker dialog.
    Is the problem relate to the file access permission grant?

    Can u please help me to fix these 2 issues?
    Thanks.

    Hi. thanks for your great package.
    I have model with 3 different material. how can I load model, each time with different mat?
    or can I have one mat but 3 texture and each time set the different texture?

    Hello,

    I am using SolidWorks to export glb files and unity with TriLib 2 to load them from disk.

    But they seem to be mirrored or rotated...

    The old 1.9 documentation here says it can be rotated by option:

    https://ricardoreis.net/trilib/manual/html/class_tri_lib_1_1_asset_loader_options.html

    Vector3 RotationAngles = new Vector3(0f, 180f, 0f)

    and

    bool UseOriginalPositionRotationAndScale = false

    Are these gone or do I just not see them?
    Am I using it the correct way?

    Code (CSharp):
    1.         private void DownloadDragModel(string uriString, GameObject downloadGo)
    2.         {
    3.             var assetLoaderOptions = AssetLoader.CreateDefaultLoaderOptions();
    4.             //assetLoaderOptions.UseFileScale = false;
    5.             AssetLoader.LoadModelFromFile(
    6.                 uriString,
    7.                 OnModelLoad,
    8.                 OnMaterialsLoad,
    9.                 downloadGo.GetComponent<DownloadPreview>().OnProgress,
    10.                 downloadGo.GetComponent<DownloadPreview>().OnError,
    11.                 downloadGo,
    12.                 assetLoaderOptions);
    13.         }
    It seems top is bottom? If I set localscale to 1,1,-1 it looks okay, or maybe if I rotate them by myself around y = 180 also okay, but in both cases they change their location because their pivot is not the middle of the object...

    How do I get out of this, any idea?

    Thanks a lot!

    Hi!

    TriLib is meant to keep the original model orientation.
    TriLib 2.0 doesn't have the option to rotate loaded models manually when loading, since it should keep the original rotation.
    I could add this option if needed, or you could send me the file via e-mail so I can check out what is wrong.

    Hi!
    I could not check out this issue yet. Still, I've included the native code for all file-picker libraries in the latest TriLib version, so you can debug it on Visual Studio while I'm still trying to reproduce such issues.

    You could create a class inheriting the MaterialMapper base class and use your own logic to handle the material variations.
    There is no sample on how to create a custom MaterialMapper yet. Still, you can check the StandardMaterialMapper.cs code, which is fully commented out and could be used as a reference.

    Hi,
    Okay, I will try to debug it.
    But please try to reproduce the issues I mentioned on your side and keep me updated as you resolved them.
    Actually, MacOS standalone build doesn't show a file picker popup at all.

    Thanks.

    I'm having difficulties migrating my project from old Trilib to Trilib 2 (and Unity 2018.4 > 2019.4). I checked the migrating example and implemented that into my code, replacing the previous version (using (AssetLoader assetLoader = new AssetLoader) etc.).

    Now I'm getting the errors such as:
    An error ocurred while loading your Model: System.ArgumentNullException: Value cannot be null. Parameter name: String
    and
    An error ocurred while loading your Model: System.IndexOutOfRangeException: Index was outside the bounds of the array.
    which don't make sense to me.
    As far as I understand the string null error traces back to AssetLoader.1045 where, after putting a breakpoint and debugging, everything seems fine. I've also tried it in the example scene (TriLibSamples/LoadModelFromFile) which gave me the same string error for the model I'm trying to load. Model's filename is: PS80801800. What am I not seeing/understanding?

    TriLib 2.0.14 is awaiting approval on Asset Store.

    I apologize in forehand for an issue I've introduced in the latest version, which prevents the GCHandler quit from forcing the GC collection. It has been fixed on the upcoming update, along with many other changes:

    -Refactored FBX mesh generation.
    -Fixed StandaloneFileBrowser not opening on Windows.
    -Fixed STL flipped normals bug.
    -Fixed GCHelper.cs always running bug.
    -Fixed GLTF blend-shape animations bug.
    -Fixed GLTF roughness values.
    -Fixed FBX ASCII reader bug with out-of-range properties.
