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’.

IDictionary<GameObject, IModel> allModels = assetLoaderContext.Models;
foreach (KeyValuePair<GameObject, IModel> modelPair in allModels)
{
    Debug.Log(modelPair.Value.Name); // Outputs name just fine
    IDictionary<string, object> userProperties = modelPair.Value.UserProperties; // Always null
    if (userProperties == null)
        continue;
    // Never reaches this code
    foreach (KeyValuePair<string, object> property in userProperties)
    {
        Debug.Log($"Key: {property.Key} --> Value: {property.Value}");
    }
}

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:

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