I'm trying to use some of the jDRP models in GZDoom and noticed that GZDoom renders the transparent parts solid: The upper part of the bottles in the screenies is supposed to be transparent. Both Doomsday (first shot) and Vavoom render it with transparency, GZDoom (second shot) does not.




Am I doing something wrong here or does GZDoom just not support transparency in models?

Spoiler: Model definition

Code: Select all

{
   Path "models/items"

   Model 0 "Bottle1.md2"
   Skin  0 "Bottle1.png"

   Model 1 "Bottle2.md2"
   Skin  1 "Bottle2.png"

   Model 2 "Bottle3.md2"
   Skin  2 "Bottle3.png"

   Scale 1.9 1.9 1.9

   Frame BON1 A 0 "Frame 1"
   Frame BON1 A 1 "Frame 1"
   Frame BON1 A 2 "Frame 1"
   Frame BON1 B 0 "Frame 1"
   Frame BON1 B 1 "Frame 1"
   Frame BON1 B 2 "Frame 1"
   Frame BON1 C 0 "Frame 1"
   Frame BON1 C 1 "Frame 1"
   Frame BON1 C 2 "Frame 1"
   Frame BON1 D 0 "Frame 1"
   Frame BON1 D 1 "Frame 1"
   Frame BON1 D 2 "Frame 1"
}

Translucency for models isn't supported by GZDoom (I tried, no luck). If alpha channels would work right they would do the job perfectly, I think P:

That doomsday screenshot looks sort of bad IMO. I don't think it fits into doom due to the hi res textures and werid lighting

GZDoom only supports binary transparency for models. Meaning the polygons will be either visible or invisible. Nothing in between is supported.

I've had luck making use of the alpha channel in PNGs for model textures, but as I've said, it's either opaque or 100% transparent.

Let me look for a post from Graf explaining why it's not supported...

Thanks for the info. Guess I'm out of luck then. It's not a big deal for the health potions, but the spheres just don't work without transparency.

The bad lighting in that shot is actually drawn on the textures being used. It is not Doomsday's fault that the texture artist who created them doesn't seem to understand how to paint world textures.

Thankfully, there are newer resources available now [compared those in that shot] which much more closely resemble the original id art asset.

Good. BTW:I meant nothing agaisnt DoomsDay. It is good for its own reasons
