Two comments: 1. It doesn't matter if it's for Mojoworld or anything else, the fact is, money is being exchange for something that the purchaser can't use in commercial projects. It doesn't specifically state redistribution of meshes, it just says non-commerical, which covers all commerical projects, including renders. 2. If the person selling these has used other copyrighted ships (i.e., from Star Trek or Star Wars, etc.), then he/she is breaking the law in the first place, and giving a no-commercial restriction is sort of laughible since he/she is breaking that rule right there.
