@protocultor Hey,, thank you man, I can now see the glowing of the eye's monsters in the dark, and machine's screens too, the only drawback is that I need to use, like you reccomend, Doom Software Renderer (+vid_renderer 0) to do the trick, because with Opengl-accelerated (+vid_renderer 0) this file (softfx.wad) apperars to do almost nothing for the bright of those elements.
With Doom Software Renderer:
doom_glowing_machinery.png
With Opengel-accelerated:
doom_no_glowing_machinery.png
Another drawback is that with "doom software renderer" I can't use "lights.pk3", I think this have to be with both files (lights.pk3 and SoftFX.wad) were made for differents renderers and because of that, they are incompatibles each other.
That's a shame, because lights.pk3 adds some nice animated light effects to some items ans such things:
With DoomSoftware Renderer:
doom_helmet_no_glow.png
With Opengel-accelerated:
doom_helmet_glow.png
Anyway I'ts an improvement, so thank you my friend, I like that glowing eyes !!
