Hi Florian,

Normally this is done via a texture atlas:
https://en.wikipedia.org/wiki/Texture_atlas

That is a large texture which contains multiple subtextures. These can then be applied to the geometry by specifying the corresponding UV-coordinates.

There is even some thing called Mega-textures, where parts of the texture atlas get streamed from disk to create gigantic virtual textures:
