Things sold from morphed characters made by Zygote in the form of cr2's are acceptable items in the store, since you are not redistributing the original Zygote/Daz3d geometry. Zygote/Daz3d has allowed this level of resale/redistribution of derivative works. Other artists however do not, so you must check with each creator individually on things you might wish to create derivative works of, or redistribute in whole or in part. Tim Laubach is very good about allowing his textures to be redistributed, but a nice note to him would not hurt a thing. He has even been wonderful enough to allow me to heavily (and I do mean heavily) modify one of his lovely textures and resell it with Delilah. Moonbiter, changing formats is just a format change, it is still the artists copyrighted work you are mucking in, and you are in fact making a derivative with the format change. Copyright is very specific, it allows artists to control distribution, copies, redistribution, usage restrictions, almost all control over their own work. Some choose to relax their control and give away control of their own choice, others do not. It all depends on the specific artist or company. Work sold in this store is sold as 3d Clipart. That means you can render to your hearts content, and sell or do anything you wish to with those renders. You can even make custom modifications to the work to make it suit your purposes better, such as change haircolor, add new clothing, adjust the texture to your liking, morph till the cows come home... on and on. But the second you take the original product, morphs, geometry, texture, bumpmaps, transparency maps, props, hair, whatever... and find a way to circumvent that artist's copyright, (his right to control it totally in it's original form and make a living off his work) and you go redistribute it without his knowledge or consent, you are in shady grounds and apt to be having to do some 'splainin.
