How can I use the NormalFromFunction node in the material editor? The description and the input pins don’t offer any explanation on how to use the function. Let’s say I want to generate a normal map from the SphereGradient-2D function, how would I go about that? I’m assuming plugging the output of the SphereGradient-2D into all three Function(UV) inputs, but I tried several different functions and values for the other inputs and I only get a uniform, deep blue output.
The documentation is also missing any mention of this function. (Procedurals | Unreal Engine Documentation)
Any suggestions?
