Does anyone know how to calculate the texture coordinates used in worldcraft 3.3 MAP files? I have converted brushes to polys. I know the meaning of those five numbers and where to find them (xscale, yscale, xoffset, yoffset, rotation) but how do i generate the starting coordinates? I found some source code on the web (qeradiant, quakeed, half-life tools) but I dont understand them they are big projects that i cant follow them(I am a newbie in C++). Can anyone tell the idea please?
