Hi everyone, this may sound like a stupid question but I have learned never to take anything for granted. I have a copy of " EllePro's" human brain, it says "unrestricted use" does this mean I can use a rendered image of this model and incorporate it into a 2D design that is intended to be sold on a T-Shirt?

I've been a bit confused recently regarding different types of usage policies with fonts, I figured 3D objects may have similar issues, free font doesn't necessarily mean free. I'm just being responsible so please don't flame me out.
