I use a Specific WordFunc Material for the textures above my tycoons buttons i have to link all the textures to a switch as you can see in the first screenshot and i have this message : ”Details cannot be shown: Substrate (Beta) is not enabled for this project” About the substrate and in game i cant see the textures above the buttons i think that its because there are too many nodes but im not sure so if someone know something about this the materials and nodes limit thanks to answer my X:@DreamsMaps
Well, this might be obvious, but are you sure the “Substrate materials” option have been checked in in the project Rendering settings ?
