OpenZone 4.8

easy in library/textures make a folder named quake3, then inside make a folder named textures inside that folder make folders named after what the textures came from in Q3(example: gothic_block).
so if i used blocks18c_3 from gothic_block you folders would be like this:
Openzone/Library/Textures/Quake3/Textures/gothic_block/(with blocks18c_3 inside of the gothic_block folder of course).
