The move by CGTrader to foist the "AI friendly" licensing scheme on artists against their will reeks of nefarious intent. The default should have been no AI licensing, thereby giving artists the opportunity to opt in, should they desire to do so. I have gone ahead and changed all my model to the Royalty free no Ai licensing, because I have no desire to participate in any 3d generative AI grift. Talk about willfully stepping on a land mine for a paltry one-time fee.
TurboSquid pulled similar nasty dubious stunt when they automatically opted everyone into some text to 3D AI scheme, before sending out e-mails stating you can opt out by selecting that option in your settings. At least with TurboSquid you are able to opt out by just pressing a button. CGtrader forces you to manually opt out.
Presently I am having second thoughts about publishing new models on CGTrader. With all the nefarious underhanded practices by 3d assets vendors regarding 3D generative AI , It's looking more like I will be going back to creating animated shorts and series, while restricting sale of 3D models to Unreal Marketplace (or FAB when it is ready), Gumroad, Renderhub and Blender Marketplace.
