I would think that if a texture pack works with an older version of GZDoom it should work with a new version.

The only way to remove the transition texture errors was to delete the texture out of the pack entirely, so I suspect you are correct. Do you know how I can go about fixing this? Is it simple a matter of taking the textures and putting them in a lump folder to exclude them from being loaded with plutonia?wildweasel wrote:If this is regarding this, then the problem is that you are trying to use a Doom 2 texture pack with TNT or Plutonia. The textures of those names in the Final Doom WADs are completely different textures.

If its fixed do I redownload 4.1.2 so I can use the TX pack?_mental_ wrote:There is a bug with hires texture pack in Doomsday format like AltDHTP. Now, it's fixed.
As for the Neural Upscale pack, the problem is in its files placement.
For example, Ultimate Doom SLADRIP1/2/3 textures are in DOOM filter directory. They will be picked as replacements for any Doom IWAD because of that.
The same applies to other cases you reported here. Neural Upscale pack causes these issues with GZDoom 2.4 as well.
