Quick-start

Install Visual Effects Graph from Package manager:

• Window/Package Manager -> Unity Registry (upper left corner) -> Visual effects graph
• Install

Check that everything is working correctly:

1. Open HDRP/URP/built-in Demo scene from OAVA-Flame/Scenes
2. Press play.
3. IF YOU GET ERRORS IN CONSOLE / FLAMES DO NOT RENDER
   1. Error: Value of name ‘Fire…..” was not found -> Open every OAVA-Flame/VFX/Flame… and close it.
   2. Shader error in ‘Hidden/VFX/…’ redefinition of ‘PackHeightMap’ -> see FAQ/I am using Visual Effects Graph 10.4.0+…

Use the system:

1. Backup materials you want to convert, just in case.
2. Select the objects from the hierarchy you want to convert to flammable:
3. Press right-click
4. Select OAVA-Convert-> Flammable…

5. Untick materials you don’t want to burn.
6. Press yes
7. Voila. Now your object is flammable.
8. Set the right settings:
   1. Add box colliders to your object if it doesn’t have them already.
   2. Or tick “Calculate flammation area from mesh”. This only works for simple meshes.
9. Test out by ticking “Set Fire on Start” on the “Flammable object” script attached to your object
