Thanks…
Any suggestions about how to get a mask of that type? In Blender is one of the first and basic node you should use in your shading model and is called “Diffuse”… I can’t believe that in UE5 it’s impossible to replicate that.
(I actually made a mask using the directional light data that is working as I wish, but I need to interact with all the lights in scene… not only the sun).
Thank you for your time.
