I'm experiencing a similar issue, but on Windows. See the stack traces I've posted above. The first one is when loading a model multiple times. Seems like the application crashes when disposing the native array in the finalizer of AssetLoaderContext. Were you able to find a solution or workaround for this?

 

hello, i am new in trilib and i have a problem. i am loading some models with a link that i get with firebase, the problem is that in windows the model is downloaded well but in mac os it can not be downloaded.
here is the error that I get.
error loading model: System.ArgumentNullException: Buffer cannot be null.

I am using trilib 2 version 2.2.0, and when i load model at runtime, the materials appear darker with fbx and glb models, not yet tested others, and i checked the main color, the base color is indeed different, anyone meet this problem?

 

@rickomax seems that you stoped the upport for this product?
I need to load the assets ina an async way and seems that trilib is not doing this also if there are code parts that seems to suggest that there is this implementation.

it is possible to have an answer?
thanks.

 

I'm wanting to do the same thing. I emailed last week and haven't gotten a response yet.
I just want to load a list of files all at once, one after the other. But I get missing object references, likely because my next file is loading before a previous file has finished.
Need async/multiple file help @rickomax. Thanks!

 

Hey everyone! When I try to load an ordinary OBJ-file with the "AssetLoaderFilePicker", the obj gets loaded, but the material and texture do not get set, and are set metallic.
Is this a common issue, and am i forgetting something, or is my apporach wrong?

Code (CSharp):

1. // Lets the user load a new model by clicking a GUI button.
2. private void myOwnFunc()
3. {
4.     // Creates an AssetLoaderOptions instance.
5.     // AssetLoaderOptions is a class used to configure many aspects of the loading process.
6.     // We won't change the default settings this time, so we can use the instance as it is.
7.     var assetLoaderOptions = AssetLoader.CreateDefaultLoaderOptions();
8.     assetLoaderOptions.LoadTexturesAsSRGB = false;
9.  
10.  
11.     // Creates the AssetLoaderFilePicker instance.
12.     // AssetLoaderFilePicker is a class that allows users to select models from the local file system.
13.     var assetLoaderFilePicker = AssetLoaderFilePicker.Create();
14.  
15.     GameObject wrapper = new GameObject();
16.  
17.     // Shows the model selection file-picker.
18.     assetLoaderFilePicker.LoadModelFromFilePickerAsync("Select a File",
19.         OnLoad,
20.         OnMaterialsLoad,
21.         OnProgress,
22.         OnBeginLoad,
23.         OnError,
24.         wrapper,
25.         assetLoaderOptions);
26. }

I just want to load an ordinary OBJ file, why is that so hard in Unity? ^^ @rickomax

 

Do you also have the mtl file together with obj in the same folder? Because the materials and textures are referenced inside mtl file.

 

Hey guys.
I'm developing new systems and finding more people to help give TriLib proper support, so I apologize if I don't access the forums too often—lots of things are in the works.
Cheers!

 

Hi, I'm interested in this lib does it also provide support for export the model at run time in different format.

 

I got the file to load, with the material and the texture, but it is super shiny and stuff, even though Blender, etc show it as matt ...

 

Hello, I am currently using TriLib 2.2.0. When I load a Gltf 2.0 file, the material mapper has some issues. It maps materials that are not “Transparent” as “Transparent”. However, when I use other Gltf loading plugins like GltfUtility or GltFast, this issue does not occur.

 

Hi! I just updated to the latest version, and now I'm unable to switch the SFB MacOS plugin to "Any CPU" to allow it to work on Apple Silicon. This worked in older versions of Trilib, but now I can only get it to work in builds on Intel MacOS Builds.

Any help would be appreciated. Thanks!

 

Hello,

This package is awesome, however, I'm running into an issue with Animations. I'm loading a FBX file from Mixamo and extracting the animation clip as follows:


Then I'm attaching the animationClip to an override controller to run on another Avatar.

But for some reason, the animationClip is still in "generic" format instead of "humanoid" format.

Has anyone had any success with this?

 

For those having trouble with using SFB on Apple Silicon, this Github issue is super helpful. You can just replace the StandaloneFileBrowser.bundle file with the ones provided here:
