Listen up folks.
Last time. Do not attempt to play lawyer with this. Period. If you take a texture and modify it then release it, you're playing with fire. Maybe someone won't notice...maybe someone will. This site cannot afford (literally) brushing up against this stuff.
Do NOT suggest what you are suggesting. Unless you're willing to pay the legal fees. Because we can't.
Now, you want to use the texture as a template for lines, colors, etc, that's okay as long as the original texture does not become part of the new texture in any way.
We have been seeing a disturbing trend around here lately with playing with copyright.
Don't do it. Not here, not EVER.
