Probably through my own lack of effort, I don't think most people know what the opengl2 renderer is capable of:
So, since no-one asked, I've decided to try making a few textures here and there. Now this isn't a proper retexturing project, as I have no plans on making the new textures slavishly accurate to the old ones. Instead, I plan on making a few nice textures here and there to demonstrate the use of OpenGL2's abilities, as well as for my own and anyone else's use in any other project.
Currently I've only done two textures, base_floor/tilefloor7 and organics/dirt, but I'll update the pack as I make new ones.
This require the latest version of ioquake3, the opengl2 renderer, Quake 3 (of course), and enabling certain cvars in the console, namely r_pbr (which I really need to document ), r_parallaxMapping, and r_cubeMapping.
Anyhoo, current pack is here: http://smiletheory.ioquake3.org/gl2_tex.pk3 , and I release this under CC BY 4.0: https://creativecommons.org/licenses/by/4.0/
