Buggy rendering with Caustics and poly selections

Corona Corona for Cinema 4D Issues

Win 10, R19, Corona Beta 1 Release

When you use a base glass material and a poly selection with that glass material plus a bump map, the render looks (literally) broken as soon as caustics are active.
You can avoid it by just using one glass material with the bump stuff on a UV map, but I liked the C4D way to mix together whatever you like. Unfortunately “Mix texture” is not possible yet either.

Reminded me of the ongoing SSS discussion.
With selections, C4D and everything transmissive, issues seem to arise.

And please move it back from “resolved” - it is not.

Thanks for bringing it up again. We’ll look into it.
