Particle system has NULL materials and wont be rendered error
This could be due to some of the project's materials being either broken or unsupported within Luna. These broken materials, from a prefab, result in an error within a Unity Playworks Plugin build. Whilst in contrast Unity would omit the broken material and simply not show the associated GameObject.
Possible solution:
- Check for a material error within the chrome dev tools console and find the game object name. Disable the GameObject that uses the broken material from within Unity and re-build for Luna.
