Thanks for shedding some light on this Houska. How does the Max version get such results out of the core? I thought it was just how C4D was connecting with the core that was the problem. The C4D one is really bad / unpredictable.
I wish Corona had taken the approach of a universal node editor that worked with every base app, so the only thing the base app was doing was handling the mapping. I can't see a downside to this if the corona material / shader system was comprehensive enough. We are getting those advanced features as it is with the Max version; inbuilt triplanar and UV randomiser etc. It seems the wheel has to be reinvented with every plugin and I'm not sure why this is necessary? Perhaps this is to do with procedural shaders but could this not be handled in the corona core?
PS any update on when we will get rounded edges back?
Nikola would tell you more about the bump since he's the one playing with it, but he's currently out of office. But he found out there are differences between VRay and Max too.
As for the node-based approach, I wish things were that simple :-)
It's not possible, because you can't have a core that will be so universal, that you'll not have to do anything (besides the mapping) in every possible base app. And remember it's not only about materials and shaders. Hooking into the app's UI can sometimes be tricky too, plus you have to map the scene with its geometry. And don't forget the IR, which is almost impossible to do in the current C4D's API :-)
