That last is not true, Gareee. Please be careful about such statements. Be absolutely sure you have the facts right before you get people in a tizzy.

The original, unmodified textures cannot be redistributed without permission. With permission, it can and has been done.

Modification and redistribution, without explicit permission, is ALLOWED AND REQUIRED so long as the texture you make is bundled with a 3D prop or figure.

Also - it is possible to speak to the owner and actually get permission for redistribution, even unmodified.

I quote from the cgtexture license: (On the site, click About then License)

Quote - CONDITIONS OF USE
Use of the Textures is only allowed under the following conditions: - Private or commercial use - Use in 2D or 3D computer graphics, movies and printed media - Incorporation in computer games, 3D models - Selling 3D models bundled with modified versions of the textures, when the texture is customized for the 3D model

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
