[VFX] Unexpected behavior after call of Renderer.material
Any access to `gameObject.GetComponent<Renderer>().material` will make the VisualEffect oddly behaves.
Step to repro:
- Import Repro_Material.unitypackage (the scene uses HDRP but the repro is compatible with URP)
- Enter in PlayMode
- Observe the color of the VFX evolving
- Click on the boolean "repro_issue" in inspector of the custom monobehavior
- Observe the color stopping to evolve
Expected:
- The color continue to evolve
Tested with 2022.1b12 & 2022.2.0a8

Latest issues
- Polyspatial Material swap set animations are not firing when used in Play Mode and Players
- Incomplete shortcuts are displayed in the "Set" dropdown in Visual Effects Graph VFX Control subwindow
- Version change sub-window closes automatically when "Add Modules" subwindow is closed
- RenderTexture content from 'Depth Only' camera is not rendered correctly on UI RawImage when Multithreaded Rendering is enabled on specific MediaTek devices.
- Weight Brush Overlay text is clipped in Sprite Editor
Resolution Note:
The material behavior is tricky with VFXRenderer, the object is mainly handled by C++
If you want to modify the actual content of a material, I advice directly modify the sharedMaterial (being aware it can be shared between several instances).
Moving the ownership to user in VFX isn't planned yet but I are considering behavior improvement.
