Hi, I've got a few questions about texturing. The game I am planning on modding is Medal Of Honor AA, released in 2002 on the idTech3 engine. I have found the texture files in the game, and can easily open and edit them in paint and it all works as it should, however, these textures are very low resolution, due to the age. I tried to increase the resolution of a bullet texture from 64x32, to 128x64 (maintained aspect ratio) however this did not work. When modding textures, do I have to keep the resolution the same, or can I increase this to HD?
