UDMF - Allow Multiple Brightness Levels on a Sidedef

[Dr. Van Nostrand]

It'd be great to have the ability to set the brightness levels independently for the lower, mid & upper textures on a sidedef. It'd allow for fake shadow casting like this among other uses:

While I agree an easier way would be nice, this can already be achieved with [wiki]ExtraFloor_LightOnly[/wiki].

[Dr. Van Nostrand]

Thanks, I didn't know about that!

I think I'll leave the feature request open though if that's ok... This seems like something that might be doable in the UDMF format that would be a lot easier. No hard feelings though if this isn't a priority.

This lights the entire destination sector, rather than One thing to keep in mind:

Note that this is implemented as a [wiki]Sector_Set3DFloor[/wiki] with invisible textures, so sector effects such as damaging specials are also transferred.

So this will have any other limitations/oddities associated with 3D floors.

Upper/Middle/Lower lighting would be simpler to set up and less weirdness-prone.

Tell that to the one who wrote the software renderer.
I once tried but the only thing where I succeeded was the texture offsets. This code is hopelessly littered with global variables which change in non-intuitive ways.
