How to reproduce:
1. Open the project the "1323870_Repro" project (the project is in google drive, the link is in the edit)
2. Open the "Terrain" Scene found in the Assets/MicroSplat/Core/Examples/Scene folder
3. In the Scene/Game view inspect the "Terrain" GameObject
4. In the Project window select the "MicroSplatConfig" GameObject found in the Assets/MicroSplat/Core/Examples/Scene/MicroSplatData folder
5. In the Inspector at the bottom press the "Update" button
6. In the Scene/Game view inspect the "Terrain" GameObject

Expected results: The "Terrain" GameObject renders correctly just like at the 3rd step
Actual results: The "Terrain" GameObject renders black (as if there were no textures)
