Platinum Arts Sandbox - Free 3D Game Maker Forum

I was reading through the sandboxtodo.txt file and I came across a line "move non-free art assets to another branch and release this that an extra"
What is "non-free art" I would like to know because I would like to help with the 3.0.0 release.

It means, that some textures and models in sandbox are forbidden to use in commerical games... so the developers are planning to remove them from sandbox. But they can't just do it because then there would be much less stuff, they have to find replacements for the stuff they remove.

are cc-by-sa and cc-by non commercial

cc-by-nc, cc-by-nc-sa, cc-by-nc-nd and cc-by-nd would qualify as non-free, though the cc-by-nd content could be used in a commercial context

Thank you Hirato for clearing that up. I appreciate it.
