TriLib UserProperties Always Null

Hi,

I am trying to get access to the custom properties in an FBX but it seems to always return 'null'.

Code (CSharp):

1. IDictionary<GameObject, IModel> allModels = assetLoaderContext.Models;
2. foreach (KeyValuePair<GameObject, IModel> modelPair in allModels)
3. {
4.     Debug.Log(modelPair.Value.Name); // Outputs name just fine
5.     IDictionary<string, object> userProperties = modelPair.Value.UserProperties; // Always null
6.     if (userProperties == null)
7.         continue;
8.     // Never reaches this code
9.     foreach (KeyValuePair<string, object> property in userProperties)
10.     {
11.         Debug.Log($"Key: {property.Key} --> Value: {property.Value}");
12.     }
13. }

I made a test_cube.fbx that has a property:

"test_prop": "abc123"

​

When I look at this FBX in Blender or Maya, I can see the custom property just fine, but it doesn't seem to work when imported with the library.

Anyone know how to get this to work?

Cheers,
Charlie

 

Nevermind, I figured it out. You need to create a mapper that plugs into the options:

Code (CSharp):

1. AssetLoaderOptions options = AssetLoader.CreateDefaultLoaderOptions();
2. options.UserPropertiesMapper = ScriptableObject.CreateInstance<UserPropertiesMapper>();
