Make Line Portals be able to fit between 3D floors

[Ivory_2505]

So as of right now, line portals only fit between the floor and ceiling. This limitation causes visual issues. If you want to put a line portal between, say, a floor and a 3D floor bridge for example, the line portal will still stretch well beyond the bridge and be visible. In order to remedy this I have found a solution that works well but comes at a cost. For example, lowering the ceiling that is right behind the line portal, making it untextured, and raising it so that it is above the floor (thus creating an invisible ceiling) works to cover the extended part of the Line Portal, however it comes at the cost of blocking the player due to the ceiling's collision. So yeah that's why we should have this feature added. Simple request

This isn't at all a "simple" request. Portals work the way they do for a reason, and making them 3D would require significant changes to the code.

Well I'm not really well knowledgable in these things, is it really that hard? I know you can make portals fit between a slope from this video I saw (I think), would it not be possible with 3D floors?

It's hard unfortunately but I did it and maybe you'd like to give it some test?

LZDoom07 and GZDoom07 v4.10.07 can do it but GL/Vulkan only unfortunately, I don't know how to do it with software/polymost renderers yet, must be a hacky hack and kind of interesting what big guys say about it

So yeah, you can walk and shoot below/above them too
