My real name is Ainas. On internet I'm also known as illicitSoul. I'm 3D environment and level designer, novel writer, craftsman, cemetery explorer and a person who love arts. I'm also a veteran modder of BF2/2142. Currently I'm studying English philology and translation.
Car texture was increased to 2K, sharpened and mixed with some bloom to get best looking result. Retexturing it by hand would take tremedous amount of time so using filters is an practical alternative.
Also retextured vehicles "eat" a lot of vram and makes game exe even more prone to crash. So I might try 1,5K sized experimental textures - an option between stability and quality.
