Kagato, in the future, if you don't know who made a texture, don't DARE make an attempt to redistribute it. If the altered textured is only for your own use, that's fine. Even if the texture is supposedly "Free for Use", which Asia definately was not, keep in mind that 99% of the artists who do contribute to the freestuff here normally have readme's saying that you cannot redistribute it. The best way to find out, is that if you don't know, ask on the forums, post a render and someone should be able to identify it for you, perhaps even tell you who created it. Then, you contact the author, and if it was indeed soemthing released as a freebie, then the original artist may be entirely okay with you posting the modifications.
