Topic -> Possible?

I'm betting not. Considering other things that Graf mentioned, doing a plane reflection on a slope would probably require more programming than Graf has the time, patience, and possibly knowledge to execute.

It totally depends on the method being used for the reflections.

Since this is GZDoom and OpenGL, this is a lot more feasible than it would be in software in ZDoom though.

It's not a matter of programming. Reflecting a viewpoint off a slope is not that complicated.
The problem with reflective slopes is that the viewpoint for the reflection would get transferred to uncontrollable positions. The result of that would be that there might be severe clipping errors that break the whole thing completely. The engine simply can't handle that case well. It's one of the issues that also limits the usability of stacked sectors. But since sloped reflections may cause other problems as well (i.e. recursions) I decided not to bother any further. I have no desire to scan through endless bug reports that claim the feature doesn't work (which indeed it wouldn't.)
