Is WebGL on the latest version

 

please support utf-8 path .

 

Hi. WebGL is not supported yet.

 

Is it on the roadmap

 

Hi,

It's not possible to open a file from local network.

Do you have an idea ?

Thanks.

 

What's the platform and Unity version you're using?

 

I use Unity 2017.3.1f1 on windows 10 64 bits.

 

Hi,

I'm having some issues with loading of materials in some IFC models using trilib. Here is an example (downloaded from http://openifcmodel.cs.auckland.ac.nz/Model?sortField=Name&sortDirection=ascending&page=2):


Model in Solibri model viewer


Same model loaded with trilib


Warnings printed in console if trilib debug logging is toggled on

These color issues seem to be somewhat random, some ifc models work ok, some work partially and some don't work at all.

Similar issues are also present with alpha materials, where they never have any transparency in them even if the alpha -options are toggled on in AssetLoaderOptions. Do you have any idea what could be causing these issues?

Best regards,
Mikko Forsman

 

Getting the following with the last few releases of TriLib:

Assets/TriLib/TriLib/Scripts/AssetLoader/AssetLoader.cs(5,32): error CS0246: The type or namespace name `AssetLoaderBase' could not be found. Are you missing an assembly reference?

On 2017.1 and 2018.1 on MacOS.

Thank you.

Hi Mikko.

Assimp team is working on IFC material issues. TriLib Assimp version is a bit outdated, but it will be even with the latest Assimp version on the next update. I'll ask Assimp team members and check if they have fixed the issues regarding IFC materials.

 

Okay, thank you for the reply.


Another question, do you have any update on the status of the .STP file support?

Best Regards,
Mikko Forsman

 

Hello, I recently purchased your plugin and have a similar problem above.
My platform is Oculus Go(Android) which uses "Snapdragon 821" as CPU.

D Unity : Unable to lookup library path for 'libassimp', native render plugin support disabled.
E Unity : Unable to find libassimp

Can I ask you the schedule for supporting this Armv8-A architecture?
I tried the plugin's Beta version on your website but it seems like it is still not support..

Thanks in advance

 

Hi there, I love you product. I just had a question about future support; do you plan on supporting STP files in the future? Thanks!

Hey, everyone. I recently came across an issue with the AssetLoaderBase.cs throwing exceptions which could not be caught due to the asynchronous logic within the loader. I modified AssetLoaderBase.InternalLoadFromFile(string filename, AssetLoaderOptions options = null) to not throw exceptions, but instead invoke an event which I setup. I decided to post an unofficial solution on this forum in case anyone else is having this issue, as well as hoping Ricardo Reis will see this and potentially have a proper/official solution. Feel free to implementing my solution listed below:

1) Declare a delegate inside of the TriLib namespace inside of AssetLoaderBase.cs just like the other delegates listed inside of the TriLib namespace of AssetLoaderBase.cs (Ex: public delegate void OnLoaderFailedHandle(string error, Exception exception);)

2) Declare an event inside of the AssetLoaderBase class, located in AssetLoaderBase.cs. (Ex: public event OnLoaderFailedHandle OnLoaderFailed;)

3) Modify AssetLoaderBase.InternalLoadFromFile(string filename, AssetLoaderOptions options = null) to not throw exceptions, but rather invoke out OnLoaderFailed event. Also, we need to change the logic to only call LoadInternal(scene, options); and AssimpInterop.ai_ReleaseImport(scene); when the TriLib loader actually worked. This is what the function should look like after making the necessary changes.

Code (CSharp):

1.  protected void InternalLoadFromFile(string filename, AssetLoaderOptions options = null)
2.         {
3.             // We must now define our scene variable because of the changes to the logic paths within this function
4.             IntPtr scene = IntPtr.Zero;
5.             try
6.             {
7.                 scene = ImportFile(filename, options);
8.             }
9.             catch (Exception exception)
10.             {
11.                 OnLoaderFailed.Invoke(string.Format("Error parsing file: {0}", filename), exception);
12.                 //throw new Exception(string.Format("Error parsing file: {0}", filename), exception);
13.             }
14.             if (scene == IntPtr.Zero)
15.             {
16.                 var error = AssimpInterop.ai_GetErrorString();
17.                 OnLoaderFailed.Invoke(string.Format("Error loading asset. Assimp returns: [{0}]", error), null);
18.                 //throw new Exception(string.Format("Error loading asset. Assimp returns: [{0}]", error));
19.             }
20.             else
21.             {
22.                 // Original code does not have the two lines under this line in an else statement
23.                 LoadInternal(scene, options);
24.                 AssimpInterop.ai_ReleaseImport(scene);
25.             }
26.         }

4) Create a function inside of the class which you are calling AssetLoaderAsync.LoadFromFile(); from. This will be the function our OnLoaderFailed event invokes. See the function below for an example:

Code (CSharp):

1.     void HandleAssetLoaderFailed(string error, Exception exception)
2.     {
3.         // ModelLoaderFailedInfo is a custom class to contain the reason why TriLib failed to load the model
4.         modelLoaderFailedInfo = new ModelLoaderFailedInfo(error, exception);
5.     }

5) Lastly, register our function to the OnLoaderFailed event.

Code (CSharp):

1.  GameObject spawnedObject = new GameObject();
2.  
3. try
4.             {
5.                 using (var assetLoader = new AssetLoaderAsync())
6.                 {
7.                     assetLoader.OnLoaderFailed += HandleAssetLoaderFailed;
8.                     var assetLoaderOptions = AssetLoaderOptions.CreateInstance();
9.                     assetLoaderOptions.AutoPlayAnimations = true;
10.                     assetLoader.LoadFromFile(fileName, assetLoaderOptions, spawnedObject, delegate (GameObject loadedGameObject)
11.                     {
12.                           //This code will happen when the LoadFromFile is done executing, [B]even if it failed[/B].This is why I  had ModelLoaderFailedInfo class.
13.                         // If the TriLib model loader did NOT fail
14.                         if (modelLoaderFailedInfo == null)
15.                         {
16.                                //Do stuff with the object
17.                         }
18.                        
19.                         // If the TriLib model loader failed
20.                         else
21.                         {
22.                                 //Destroy the object or do whatever you want. You [B]can[/B] call Destroy() here because this code will be on the main thread that Unity runs.
23.                         }
24.                     });
25.                 }
26.             }
27.             catch (Exception e)
28.             {
29.             }

If you have any questions, feel free to ask! I will try to answer quickly and help as much as I can. I hope this solution helps, and sorry for the long post! Here is a potato: 0

Note: Be sure to have "using System;" & "using TriLib" at the top of your file.
For those wanting to use the ModelLoaderFailedInfo class:

Code (CSharp):

1.  class ModelLoaderFailedInfo
2.     {
3.         public string triLibErrorMessage;
4.         public Exception triLibException;      // Can be null
5.         public ModelLoaderFailedInfo(string ptriLibErrorMessage, Exception ptriLibException)
6.         {
7.             triLibErrorMessage = ptriLibErrorMessage;
8.             triLibException = ptriLibException;
9.         }
10.     }
11.  
12.     ModelLoaderFailedInfo modelLoaderFailedInfo;

Edit 1: Fixed formatting issues

 

Hi @BrandonF_doghead and thank you for your feedback.
TriLib already has code to deal with exceptions thrown on other threads.
I'll take a look at your solution and check if I have missed something on my implementation.

Thank you!

 

Hey, @rickomax! Sounds good. Thank you for the reply!

 

Hey, everyone. I have gotten this error message with two separate FBX models.

https://imgur.com/EIKdN5E



@rickomax Do you know of this issue?

 

Hello everyone,

I got a few models that do not import with the asset. Everything worked fine with my own models (fbx from Maya and 3Ds), but we got an event tomorrow and I just get the models from my customers (CAD transformed into a fbx) which work partially with Trilib.

Do anyone knows a pipeline to clean a model so it does work with Trilib ?

More info :
I have to download the models from a web server, then save them and vizualize them into hololens headset, and then be able to load them from the datapath without any connection.

With my models everything works fine. With the others, I managed to load them, save them, and see them from the server ; but when I load them from memory I only got the correct node hierarchy with no Mesh Filters and/or Renderers on it.

I tried to clean and reduce the mesh (deleting history, curves, cams, lights etc) but nothing did it.

I sent a mail to Ricardo last week but not sure he'll answer in time...

If any of you got a idea ?
thanks

 

Hello,

I am using it on Daydream device - Lenovo Mirage Solo. I get error saying file cannot be opened. I tried FBX, OBJ and IFC file. It doesn't give me anything else about the error. What could it be?

Thanks.

Derek

 

hello ,there is a bug compare between unity editor fbx and trilib import fbx



and use trilib



how to fixed that?

 

This issue should be fixed on the latest update. Have you updated TriLib from Asset Store?

 

Hi. I've answered you by e-mail and seems the file you're testing has additional data Assimp cannot read. I'll try to understand and implement this data myself or delegate it to my Assimp team partner.

 

Please send your file for testing to:
contato@ricardoreis.net

 

Hi. I've never seen a MeshRenderer being disabled when importing a model directly in Unity. Is there a specific reason why it needs to be disabled? Also, what'ws the file format you're importing?

 

Hi,
I am using Unity 2017.3.1f1 and Trilib 1.8.4 on OSX
I enable DevIL but model with bmp models do get loaded.
You can test this also, just run the AssetLoading sample, and load the following cubes.
One has jpg texture and shows up fine. The other has a bmp. Pictures attached.

https://www.dropbox.com/s/2hzaf2h8k47fz9o/Crate.zip?dl=0
Does OSX support DevIL and loading of the images DevIL supports?

A relevant question
How can i remove the question mark texture when no texture is found upon loading?I would prefer to not load anything instead of showing the question mark.

Thanks
Dimi

 

Hi. I will be testing your model soon.

Best regards,
Ricardo Reis.

 

Hi this is just a reference model that displays the problem. I did the test on Win10 and the bmp textures Do show up. But on OSX the bmp texture does not load. I also used the trilibtest.zip viewers available on the site.
On OSX DevIL must NOT be working.....


How can i remove the question mark texture when no texture is found upon loading?I would prefer to not load anything instead of showing the question mark?

 

Hi. I would ask you to wait some days as I will replace DevIL by a newer and better licensed alternative which should work fine on any platform. About the question mark, I may create a patch to remove the blue question mark that is created by TriLib, but the red question mark is internal to Unity when it cannot find any appropriate loader for the texture.

 

Hi. i bought TriLib, when i test the model in the sample application it loads and when i run from the unity editor or from the build from unity it fails to load and give me this message:

Can you help me with this thanks.

 

Hi. The latest TriLib update should fix this issue.
Could you update your TriLib version and tell me if the issue persists?

 

Thanks, please inform me. Can we expect something soon? have a look at freeimage i have used it in the past for many projects also on OSX.

its strange because in the sample program trilib it loads the same file ok but when compiled in unity it dosent load.

 

That's exactly the library I guess I'm going to implement. I don't have an ETA yet, as I'll have to test this native library on every TriLib platform, and that can take some time, but I'll definetly start the implementation this week.

 

The latest update from Asset Store should fix this issue.
Have you downloaded the latest update?

 

I assume you have confirmed that DevIL is not loading/working on OSX? Even when using it outside of Unity?

 

It has been tested on OSX and was working fine on the latest test I've made. Anyway, I will redo all the tests with FreeImage when it has been implemented.

 

I tested with the Asset store version and the one from the invoice from your site, even with the version 5.6.2 from unity it doesnt load. it only load with the Trilib sample application from your website that i think is from version of Unity 5.6.2.
Have you compiled an application with an early version of Unity? I would like to use trilib to load big FBX files, some i tested loading them to bender application and then export them and they work but for bigger files this method is not a solution, i need to load them directly with trilib to unity. If you can help i would be appreciated.

 

There is something not right here. Did the cube obj mode i send above with the bmp texture load up in your test? Really?
In the Texture2DUtils.cs , in the ApplyTextureData() which is used for loading the textures the DevIL part is
commented out with an #if statement for OSX..... It does not use the IlLoader, but the Unity LoadImage, which supports only png/jpg.

Have a look yourself. Line143 in Texture2Dutlis.cs, in the ApplyTextureData() function you can clearly see that for OSX the DevIL is not used only for windows......

Code (CSharp):

1. #if (TRILIB_USE_DEVIL || USE_DEVIL) && (UNITY_EDITOR_WIN || UNITY_STANDALONE_WIN)
2.             return IlLoader.LoadTexture2DFromByteArray(data, data.Length, out tempTexture2D);
3. #else
4.             tempTexture2D = new Texture2D(2, 2, TextureFormat.RGBA32, true);
5.             return tempTexture2D.LoadImage(data);
6. #endif

If you would add UNITY_STANDALONE_OSX (i just did ) the textures load up.
Is there a reason you use DevIL loading only for windows?

Please have a look, its important....


Thanks
Dimi

 

Your TriLib version is outdated. Please download the latest Beta version from:
https://ricardoreis.net/?p=217

Also, please make sure you make a clean TriLib install:
https://ricardoreis.net/?p=282

 

You are right i thought i had 1.8.4 but i had an older version. I can confirm that in 1.8.4 (current) and 1.8.5c (beta) the textures load up fine and DevIL is used.

Can you add a place inside the Unity package (a text file or so, or in source) where the Trilib version is noted. There is no way to find the version after its added to a unity project.

Thanks
Dimi

 

I tried the Beta and Current Versions and it gives me this error: System.ArgumentException: An element with the same key already exists in the dictionary.
The only that loads the file is the AssetLoader Sample application from the website.
I am tring to make a VR application to view models and im depending from loding the models with Unity so i need the application to work maybe??
I tried a clean install to unity project and dont work. I even tried version 5.6.2 and it still dont compile and work like the sample AssetLoader application.
I do not understand what it means the error System.ArgumentException: An element with the same key already exists in the dictionary. and the cause of it and how to repair it, need help if possible thanks.

 

Hi. Could you send the full error log to contato@ricardoreis.net?

 

@rickomax

Hi,
Have you looked into 3D models loading freeze issue. I am using Trilib and found that while loading 3D model there is a freeze to the game. Is there any work around....

i am using

Code (CSharp):

1. assetLoader.LoadFromFile(assetPath);

to load the assets
