I can see in the UI a button entitled set next a counter named Methods but clicking doesn’t allow anything?

So the answer is no ??...

Only 3 methods (fog environement and outline) are now currently supported in Prefab 2.124. Most will of course follow…

In case you haven’t found yet how to make a method: you need to pick one type and press new. Set it up,  Select one or more meshes, and press apply btn. That’s all. You can remove them from a single mesh by accessing the material and its methods list. You can also set them from there too.

Ok thanks for your answer!
