TriLib - Model Loading Package

It looks like you're right - your vertices count is too low but my model got many UV sets.

And anyway this is a big regression, we are stuck to v2.1.6. Whilst waiting for an actual fix I can only advise you to stay at this version (or maybe 2.1.7 but I cannot guarantee it).

 

Anyone having this error while using siccity GLTFUtility with ready player me plugin and Trilib?

Code (CSharp):

1. Scripted importers Siccity.GLTFUtility.GLBImporter and TriLibCore.Editor.TriLibGLTFScriptedImporter are targeting the glb extension, rejecting both.
2. UnityEditor.Experimental.AssetImporters.ScriptedImporter:RegisterScriptedImporters()

 

Hello,

I'm having trouble importing correct physic camera options from FBX.

Here's the camera settings which have been imported by Unity Editor (left) and Trilib (right):



In particular, look at Field of View, Sensor Size and Focal Length.

Please, note that in order to show physical properties, I had to add the following line to AssetLoader.ParseModel():

unityCamera.usePhysicalProperties = true;

I there something I can do to import correct camera options with Trilib 2.1.8?

Thank you,
Francesco

 

Hi I have a question before I purchase it. I plan on using it for GLTF2 format. Does it load objects separately per material or does it keep the original structure and pivots/origins? I am using a free importer right now and it is much slower than the Kronos importer they provide, but it doesn't split it up by material, which is something I need as I need them to have the original object list and original pivots set in Blender. If I have "Car", "person" and "ground" in my scene for example, and each one has 2 or 3 materials, I need it to import at runtime with "Car", "person" and "ground" with all of their materials on it instead of split (ground_mat1, etc).

 

Hi, awaiting a response

 

Hello Ricardo,

I used AssetLoaderOptions.UseOriginalPositionRotationAndScale = true option at old version.
But in version 2.0, do I have to rotate Y 180 degree after model is loaded?
I tested the same model, in old version with this original transform option and new 2.0 version loaded model looks different. (Y 180 rotated)

Of course I can manually rotate Y 180 model object. But I have to handle this transform modification when load and save 3d model data, or it could make some trouble. I load model and rotate Y 180, when I save model rotate Y -180 to restore, though.
FYI, I loaded COLLADA (dae) model file.

Thank you!

 

Hi!
It's about importing a model using "AssetLoaderZip.LoadModelFromZipStream".
The ZIP file contains multiple FBX files.
Still, the result is a single GameObject.
Is there a way to import GameObject separately for each FBX file in the ZIP file?
Thank you in advance.

Trilib error with mac os TriLibCore.fbx

hello
How are you, I wanted to tell you about the following. We are having a problem with the implementation of TriLib 2.1.8. The error we presented on Mac, this error is duplicated with the shap-zip-lib@1.2.2 library. We deleted the .dll but now it doesn't. It registers another error in which it tells us related to TriLibCore.fbx. Could you help us? I'll send you the screenshots to solve them, please. This only happens to us on macOS

 

hello,

On loading fbx models, these 2 texture import errors break trilib importer.

I have tried various import settings and the only option is to switch the Generate MipMaps off.

The below errors come from the AssetViever scene.

This is the latest (2.1.8) version. (Unity 2022.1.0)

During the destruction of Mesh and while downloading the materials, I encounter this error. Is there a solution?

some time the player cancel the game before the mesh get all texture ..
and the mesh must be destoyed in the midile of geting the texture .

 

@rickomax Hi, I just want to let you know of a small bug:

When using the standalone file browser code on WebGL, the little "Select File" HTML that gets added on the page doesn't hide itself when you click "Cancel", only when you select a file. Is that something that can be changed?

I added this line to the JSLib file to hide that section entirely, and it works, but I want to make sure that it also gets removed when the user clicks cancel. Or does it not matter?

 fileInput.style.display="none";

Also, WebGL only works with the Async file browser code? In my desktop app I use the regular one, but I'm starting to build for WebGL as well. So I don't have to write two different functions depending on the platform, can the Sync/Regular one default to Async if it's unsupported?

Thanks!

 

Please, this package desperately needs async model loading in WebGL! So far it freezes when a new model is loading in! If anyone has any workaround I'd be super grateful if you shared it, otherwise please, developer, make this your top priority! Hopefully its not a showstopper Unity WebGL limitation!

 

Hi!
And sorry guys. I generally don't access the forum, so always try to reach me on Twitter or e-mail.
That is the point I'm focusing with the upcoming update, but WebGL on Unity doesn't have threads support as far as I know, so there isn't much I can do about it besides trying to make things faster to decrease the stall.

 

Is there any way to spread out the loading over different frames that way it loads slower but does not stall at all?

 

Been answered by e-mail, but yes, TriLib methods will be slowly ported to coroutines.

 

Hi!

Async methods are not supported by WebGL.
I will look into the display issue.

 

Hi!
Please make sure you have updated TriLib to version 2.1.9.
The cancelation might happen because of the Timeout field of your AssetLoaderOptions instance.
You can try increasing this value.

 

Hi!
I guess this issue has been fixed on update 2.1.9, could you confirm it?

 

Hi!
I haven't seen such issue, but removing the SharpZipLib that comes with TriLib should work, as long as you have another SharpZipLib version in your project

 

Hi!
Not natively, you would have to scan the .Zip file contents yourself and load each file at once. You can see how TriLib finds model files inside the Zip file in the AssetLoaderZip.cs source

 

Hi!
I'm working on improving Collada support (which is broken in version 2.1.9). Remember Collada support is experimental, but I should have a hotfix for it released soon.

 

TriLib will keep the original objects structures/pivots. For FBX files, the old pivot implementation was broken, so I'm working on a new one for the next update (after 2.1.9), but for the other file formats, it will keep the pivot as the original one.

 

Could you e-mail me the model with the camera you're trying to load?
https://ricardoreis.net/contact

 

You can disable TriLib editor importers under the "Edit->Project Settings->TriLib" menu.

 

TriLib 2.1.9 has many mesh fixes/improvements.
Regarding UV sets, the new update will always use the 4 UV sets if the model has only one of them.
That was a last-time addition to make the mesh system work with newer Unity versions, and it should be improved to use more compact mesh components in a future update.

 

Hi,

there's no way to attach files in the form. Could you please send me your email address?

Thanks,
F.

 

Sent you by PM.

 

Hi, a small question. Is it possible to skip loading materials with your script? My game update materials separately from the model, I'd just like to load the model data, not its materials, not sure if it's actually possible? But I see two different functions in your assets, one when model is loaded and second for material load. Can the material load be skipped completely since my script will overwrite them again later anyway? Thanks in advance.

 

From my understanding, you can disable texture loading using the AssetLoaderOptions object passed into the loading functions.

Without a material, a mesh won't render in Unity, so regardless of textures or not, materials will still be generated/allocated.

Hope that helps!

 

Bought the asset. Works out of the box. All good!
But it isn't loading draco compressed glb model on WebGL platform. Is it supported on WebGL???

 

hi mates, I hope you all are doing well.
1:I want to import multiple models at the same time. Right now I can select multiple models but only the last one selected is getting imported. Does anyone know, how to do that?

2: In Mobile devices while importing models. The file picker panel is showing me all types of assets while i set the extension to only .fbx, in the editor it is working perfectly but on mobile devices it is not.
Kindly help me with those queries. Thanks in advance.

 

Hey guys!

I just updated from 2.1.2 to 2.1.9 for the performance increase, but I'm having a couple of issues when running deployed to a first gen Hololens(it works fine in editor).

First: the obj loader throws the following error:

15. UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr)

Second:
While debugging on the deployed hololens, the device eventually hits an exception that simply states ProjectName.exe has triggered a breakpoint, at the following point in the il2cpp code:



Any thoughts as to possible causes?

Thanks!

 

Hi,

I download TriLib 2 version in 2.1.9 ,use unity 2021.3.10f1 for windows10 and Enable gLTF2 Draco.

Open LoadModelFromFilePocker Sample to load .glb file download from
https://github.com/KhronosGroup/glT...0/DamagedHelmet/glTF-Binary/DamagedHelmet.glb
then find error.

How can I fix it?

Thanks.

 

Hello, I am using Trilib 2 with Unity 2020.3.46.f1 for loading an FBX file on Hololens2. This is working well but I have an UI issue of everything freezing for sometime while the model is loading. After spending a couple of hours searching and trying options, I think I have found out that the

Code (CSharp):

1.                 ThreadUtils.RequestNewThreadFor(assetLoaderContext, ref assetLoaderContext.CancellationToken, LoadModel,
2.                     ProcessRootModel, HandleError, assetLoaderContext.Options.Timeout, threadName, !assetLoaderContext.HaltTasks,
3.                     assetLoaderContext.OnPreLoad);

execute itself on the main thread. I have also forced the Async attribute in assetLoaderContext to be true.
The profiler is giving me this :


Am I missing something ?
Thx

 

Hello, I am having an issue with the file path when building it for iOS. It's working fine in the editor. But when build it for iOS, I am getting the below error message.



I couldn't find any reference related to Unity for the above error message. Can you help me fix this?

My Unity Version is 2021.3.23f1

 

Did you solve this issue? I am facing the same. It would be really helpful if you can help me in this. Thanks !

 

Hi!
I updated to version 2.1.9 and tried it, but I still have problems with the smoothness value.
Regardless of the set value, it is unconditionally set to 1.
Is there anything i can try?
We are testing by downloading characters from the site at the address below.

+) The color value is not being reflected.

Hi,

I am having the same issue with the imported asset materials.
The materials appear 100% reflective until the material dropdown is clicked in the inspector.

I tried to change the material base color alter the mapping at runtime did not fix the issue.
Please see attached pictures for reference.

I am running Unity 2020.3.25, URP, Vulcan
I tried w the default and a custom assetLoaderOption

 

adding this to the materials loaded callback helped

foreach (var kvp in assetLoaderContext.LoadedMaterials){
Material mat = kvp.Value;
mat.SetFloat("_Smoothness", .5f);
}

 

Hello, please help me
i load stl model. In hierarchy tree, i see my model with child "default", all setting from assetLoaderOptions, apply for "default". How apply settyngs for model, withot default ?

 

Hi guys,

I am using Unity version 2022.2.19f1, and when I'm trying to debug my project, I keep getting these errors.
This breaks Unity's UI.
Anyone getting this issue?

 

I want to know how to load a pmx file for MMD?
I saw the relate post is in 2019, is the problem solved?
I have the 2.2.0 version but still can't load pmx file
Or is there anyting need to be set?

 

Is there any chance of sharing the source code for current versions? I need to make custom changes on some importers. Closed assets are really bad for that. I sent you an email with more details.

 

I would also very much prefer if the source code was accessible to make custom changes, as mentioned by @Marcos-Elias The assemblies can be easily extracted anyway using tools like ILSpy, but it's just unnecessarily cumbersome to maintain it when merging it with newer versions of TriLib, for example.

 

Is it possible to make a texture read/write? It looks like the functionality may have been deprecated?

MarkTexturesNoLongerReadable: "To reduce allocated resources, all TriLib Textures CPU data is released after the Texture is loaded, turning the Texture non-readable."

Would making a custom mapper where I manually copy and import the textures separately as read/write be the right approach? Or is there an easier way?

Any time I try do something like

TriLibGameObject.GetComponentInChildren<MeshRenderer>().material.mainTexture

it wont let me read the texture.

 

Hi everyone! Has anyone who's been using TriLib version 2.0.0 to load models on mobile devices (iOS, Android) experienced a crash after loading the second model? I've been facing this issue where even after destroying the previously loaded object and releasing the unused assets, the app still crashes when attempting to load another model. The error message suggests a memory leak.

To reproduce the issue, follow these steps:

1) Edit the scene file at Trilib/TrilibSamples/LoadModelFromURL/LoadModelFromURL.scene.
2) Add a button called "Reload" with an action below.

public void ReLoad()

        {

            if (objectLoaded != null)

            {

                Destroy(objectLoaded);

            }

            var assetLoaderOptions = AssetLoader.CreateDefaultLoaderOptions();

            var webRequest = AssetDownloader.CreateWebRequest(ModelURL);

            AssetDownloader.LoadModelFromUri(webRequest, OnLoad, OnMaterialsLoad, OnProgress, OnError, null, assetLoaderOptions);

        }

3) Build this scene for iOS/Android.
4) Launch app -> Click the "Reload" button.
The crash occurs on the second or third reload.
If anyone has encountered a similar problem or has any insights on how to resolve this issue, please let me know. Thank you!

 

I'm using Trilib 2 to load models and i get frezzes when the model load, investigating seems that the load happens on the main thread, so i found that there is a define symbols: TRILIB_LOAD_MESHES_ON_PARALLEL_THREAD
tha i think will use another thread to load.

when i enebled this i get an error in assetloader on this method calls:
Extensions_2020_2.GeometryGroupExtensions.GenerateMeshParallel(model.GeometryGroup, assetLoaderContext, dataArrayCreationContext.DataArray, i);

The name 'Extensions_2020_2' does not exist in the current context

so where i can get this Extensions implementation to make things works?

 

Hi,

I'm using TriLib 2.2.0 and I found an issue when importing multiple models asynchronously in parallel. Here is the code I use:

Code (CSharp):

1. private static void Import(ImportedModel import)
2. {
3.     CacheEntry entry = new(import.Path, import.Included);
4.     if (cache.TryGetValue(entry, out var cached))
5.     {
6.         UnityEngine.Object.Instantiate(cached, import.ModelParent);
7.         return;
8.     }
9.     Stream stream = DeserializationUtility.OpenStream(
10.         path: entry.path,
11.         withinArchive: entry.included,
12.         junk: out IDisposable junk);
13.     if (entry.included)
14.     {
15.         // Stream is a deflate stream when the file is included in the
16.         // save file's archive. TriLib accesses Stream.Length which is
17.         // not supported in DeflateStream, so we copy the stream to a
18.         // memory stream.
19.         // Not using AssetLoaderZip because it loads all files from the
20.         // archive, but we only want specific ones.
21.         MemoryStream memStream = new();
22.         stream.CopyTo(memStream);
23.         stream.Dispose();
24.         stream = memStream;
25.     }
26.     AssetLoader.LoadModelFromStream(
27.         stream: stream,
28.         filename: entry.path,
29.         fileExtension: Path.GetExtension(entry.path),
30.         onLoad: context => Dispose(stream, junk),
31.         onMaterialsLoad: context => OnMaterialsLoad(context, entry),
32.         onError: OnError,
33.         wrapperGameObject: import.ModelParent.gameObject,
34.         assetLoaderOptions: Refs.AssetLoaderOptions);
35. }

This code is invoked multiple times from an asynchronous context (but on the main thread). Here is the stack trace of the error I get:

Code (CSharp):

1. ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
2. Parameter name: index

This does not happen every time, but quite often. Let me know in case there is anything I can do from my side to help troubleshoot this.
Also I think I found a memory leak in AssetLoaderZip.ZipFileEntryToStream:

Code (CSharp):

1. /// <summary>Copies the contents of a Zip file Entry into a Memory Stream.</summary>
2. /// <param name="fileExtension">The Model inside the Zip file extension.</param>
3. /// <param name="zipEntry">The Zip file Entry.</param>
4. /// <param name="zipFile">The Zip file instance.</param>
5. /// <returns>A memory stream with the zip file entry contents.</returns>
6. public static Stream ZipFileEntryToStream(out string fileExtension, ZipEntry zipEntry, ZipFile zipFile)
7. {
8.     var buffer = new byte[ZipBufferSize];
9.     var zipFileStream = zipFile.GetInputStream(zipEntry);
10.     var memoryStream = new MemoryStream(ZipBufferSize);
11.     ICSharpCode.SharpZipLib.Core.StreamUtils.Copy(zipFileStream, memoryStream, buffer);
12.     memoryStream.Seek(0, SeekOrigin.Begin);
13.     zipFileStream.Close();
14.     fileExtension = FileUtils.GetFileExtension(zipEntry.Name, false);
15.     return memoryStream;
16. }

zipFileStream is closed, but never disposed.

 

I also get a lot of crashes with this plugin. Here is a stack trace:
