Let's put this simple. I've got a texture, but I want to use only a small part of it to map a rectangle. Is there any way to tile it instead of stretching it? (BTW, no, I can't create a separate texture for every single part of it - basically it is a skin for a 2D interface) Thanks in advance

Not easily. You could either tesselate your geometry so that the section of the texture is mapped once on each tesselated block, or you could use a fragment program to tile the texture segment, but beware of boundary issues.

Enigma

So, I guess this is something you're not meant to do in OpenGL.
No big problem.

Thanks anyway

no, but it would be nice to do that because it would speed up the graphics.
The normal way to do that type of tiling is to create a separate texture just for that tile.
It might be saved in the same image file but at load time you create a texture of just that tiny little area.
