I’m a recent lurker/hobbyist looking to pick up UE4 in the coming months and have started doing a bit of research around its capabilities. I’ve started with the material system and I like what I see so far; I think I mostly understand how I would construct things. However, I haven’t quite internalized all the possible ways materials may be combined and how that relates to a material’s singular lighting model.
Which leads to Mix Shaders:
I admit, part of what I like to do with materials involves things like Glass/IoR/Translucency and I’ve already gathered that those are not available today. However, theoretically if UE4 one day gets Glass and Translucent lighting/shading model support, would something like the following be possible (see the Cycles Material Section): http://www.mclelun.com/blog/2014/08/blender3d-cycles-crystal/
The following alludes to the answer being no – in other words, no combining of shading models, you need to make a new model if you need something like this:
Or did I misinterpret the above link and something like this would be possible now?
