Install Visual Effects Graph from Package manager:
- Window/Package Manager -> Unity Registry (upper left corner) -> Visual effects graph
Check that everything is working correctly:
- Open HDRP/URP/built-in Demo scene from OAVA-Flame/Scenes
- Press play.
- IF YOU GET ERRORS IN CONSOLE / FLAMES DO NOT RENDER
- Error: Value of name ‘Fire…..” was not found -> Open every OAVA-Flame/VFX/Flame… and close it.
- Shader error in ‘Hidden/VFX/…’ redefinition of ‘PackHeightMap’ -> see FAQ/I am using Visual Effects Graph 10.4.0+…
