I have now added some duplicate voxel files to fill in for Smooth Doom's extra frames, which I think should make it work with Brutal Doom too. I didn't like making a new actor, especially when that mod needs its own barrel actor.
I noticed Smooth Doom does some palette swap or whatever to make that gore sprite (POL5A) turn blue or green, and that definitely doesn't work with my voxels. That's the big thing I don't understand.
As for the screenshot: that's the software renderer, right? If it is, you should use this one for Strife: https://www.dropbox.com/s/b8k98l8692954 ... s.pk3?dl=0
I probably should reorganize my ModDB stuff and add that to it.
Anyway...if anyone is interested in the story about that:
Strife did a trick with the colormap so that the darker shades of certain colors aren't actually dark, if that makes sense. It didn't use brightmaps like we do now. As far as I can tell, the software renderer still uses that colormap (when not in truecolor mode), so it actually applies to voxels the same as sprites or anything else. OpenGL mode doesn't do that, nor is there any way use brightmaps or alpha channels in voxels (that I'm aware of). I get weirdly super upset when my voxels don't look right, so I developed a technique of layering voxels as a workaround. Different parts have to be separate actors so I can control what's fullbright. That lantern/street light is the first one I got working, incidentally.
So what you're looking at in that screenshot are two voxel models (and actors) in the same spot, one for the pole and ring and such, and one for the orange bright parts. In OpenGL, you can have the ring go around the other model and this all looks right, but in software it's like voxels are rendered completely separately and then placed in the world as if they were 2D sprites. I don't know how it works, but what you see there is always the end result.
TL;DR: Strife in software mode doesn't need my workarounds and can't render them as intended anyway.
Also, I apologize for never getting around to fixing Strife's torches and such.
