I have been playing through the "Back to Saturn X" megawad and I'm loving the effect of all the custom textures. However, after playing other vanilla-textured megawads and the original IWADS with the DHTP, I find that the low resolution of custom textures is a bit distracting to me. So I figured that I would fire up Photoshop and create high-res versions of them just for my own satisfaction.
My question is this: How should I structure a .pk3 file so that my new textures will replace the custom textures that are packaged in the Saturn X WAD? I've tried creating a repackaged copy of the DHTP with my test texture included in the DOOM2/TEXTURES folder, with no success. I also created a new PK3 file with just the test texture, and had no success.
Luckily, I only created one test texture so far, so if this simply not possible, I won't have wasted too much of my time.
Thanks in advance for your advice!
