What is texture license? Not source license.

Anyone?

Well, we formally have no separate license for textures. I would stick CC-BY on my contributions, but I'm not sure about others.

Note: looks like Wikipedia allows MIT license on images that are part of software package. This may apply here too.

Note2: It is possible that images are unlicensed, since MIT applies only to software, but IANAL.

I would agree with @boq on this for any art I might have contributed. I think that is the general feeling in OpenMods, attribute OpenMods as the author of the content, and then feel free to do what you like with it.
