I am rather new to UE4, comming from Unity.
How do I make multi-pass shaders? I can’t find any option for this in material editor.
While UE4 material editor covers most of shader creation needs, some features are not available, multi-pass shaders in particular. In common cases there is a workaround for that. You should describe the effect you are after to get more detailed answer.
I ask because want to make outline for creatures. I used two pass shader in Unity for that.
