This is a part of the license included in my Asia and Yuma Package as in the whole Renderosity Products. "The Artist (Author) retains all copyrights to the enclosed materials. The Buyer is not purchasing the contents, only the right to use the contents. The Buyer may not redistribute this archive file, in whole or in part. The Buyer may not store it any place on a network or on the Internet where it may be referenced by a third party. Buyer acquires the copyright to any derivative works created using this work, provided none of the original materials can be extracted from the derivative work by any means. If Artist can show that any of the original material can be extracted from Buyer's derivative work, Artist can demand both the original and derivative work, and all copies thereof be deleted. For example, Buyer cannot make an image of a texture map mapped to a flat plane, such that the original texture map can be cut & pasted from the image. This is designed to protect the Artist from Buyers releasing work, which lets other users obtain the copyrighted material, and is not meant to infringe upon the artistic endeavors of the Buyer."
