Ok, so I'm using the HIRESTEX.lmp and was wondering how you would get Hi-Res textures to WARP like lo-res textures did in regular Zdoom using the Animdefs.lmp.
You can't. Hires textures are too large to be efficiently warped. Warping one 256x256 texture costs so much time that the frame rate noticably drops. That's why warping for them is disabled.
