I have setup a material created in Substance Designer that has a parameter to control the roughness level and diffuse (parameter named wetness) to appear wet. I have set up a timeline to change the value from 0 to 1 over 10 seconds and I can visually see this happen on the material instance slider, however it doesn’t seem to update the material in real time on the mesh. Am I missing something?
Won’t let me upload images for some reason so here are some links
