I’m experiencing a similar issue. Maybe i did something wrong with the setup but i can’t get anything different to show up when the material is applied to the blendables, no matter if the meshes are with the Render Depth option checked or not.
My setup is:
-Just a new 3rd person template
-Copy/paste the 2 files you provided (the material and the material parameters)
-Had to reassign the mat parameter collection in every node where the material parameters collection is used because it was in a “unknown collection” state
-Connected == pin in the IF in the red facial shadows code to the same pin as the >=
-The compiling errors dissapeared with that.
-Added the material as a blendable to the post-process (which is unbound)
-And there is no change at all just a little darkening in the global illumination. Like if i get the light source and reduce the intensity value but nothing else.
Am i missing something? (and yeah i connected those pins in the IF because i’m using 4.6.1). Do i have to make any special setup in the meshes materials?
