I would like to convert some of my maps to tesseract, but for them to look nice, Tesseract needs more textures. It would be simple, of course, to just copy over textures from Sauerbraten for the maps. (as some have already done, it just makes the download file large)

However, my question from this is: Are there any textures in a Sauerbraten release that have licensing that only allows them to be used in Sauerbraten, not just the Cube 2 Engine in general?
