Convert a solid object and want to use flammable shader (Burnt and crackling effect)

Example Use Case: You are using HDRP/URP, You want a chair to be able to catch up in flames. You want to use a shader provided in the Ignis package for extra touches.

  1. Select object(s) you want convert in object hierarchy (scene or prefab)
    1. Can be a parent which holds many LODs or child objects that you want to act as a single flammable object.
    2. Or can be a single object.
  2. Right-click -> OAVA-Convert -> Flammable object
  3. Select materials you want to convert and click yes (can be ctrl+z:d)
  4. Now objects you had selected have a custom shader (or custom shader is on their children) and script called “Flammable object”
  5. Place box colliders on the object/children to have precise flame and spreading positions OR Select Flammable Object -> Calculate flammable area -> Object for approximate area around object. If the object is not rectangular it’s usually good to tick “Use Mesh Fire” as well to calculate flames around the mesh.
  6. Customize the rest of the options.
