- Crash on mono_dump_native_crash_info when changing a Particle System Renderer’s Material Shader to Standard Unlit
- VFX Prefab doesn’t have Preview icon in Project window and Preview window is empty in Inspector window
- Visual Effect Graph error message does not disappear and lasts forever until the Visual Effect Graph is reopened even when the error causing connection/node is deleted and Visual Effect Graph is saved
- “RenderSettings customReflection texture has invalid type” error keeps getting thrown even when Environment Reflections was set back to Skybox from Custom with an invalid texture
- Particle System with the custom Material breaks the Scene view when the material is using a Shader Graph with the Texture with the power of negative value
Resolution Note:
Unfortunately we do not support the drive info calls on IL2CPP builds. The crash should actually be a not supported managed exception rather than a crash, we will get that cleaned up asap. These calls are only available on desktop platforms and if they are needed for the project, Mono will have to be the selected back-end rather than IL2CPP.
