Does buying a CGTrader model give me exclusive rights?
Not under the standard purchase described in CGTrader’s help. Its FAQ says the designer retains rights and can sell the files more than once. Check your particular agreement before treating another sale or use as a violation of exclusivity.
The CGTrader exclusivity FAQ explains the standard arrangement. If someone offers you an exclusive deal, identify the actual license and seller making that offer. The standard FAQ does not establish the terms of a separate custom agreement.
Repeated previews can raise a different question: is this seller authorized to offer this model? Use the CGTrader profile guide to distinguish the public account references, rather than assuming either that all repeated listings are legitimate or that they all violate your rights.
Keep the specific listing and exclusivity claim with your purchase terms when asking about the discrepancy. Public username search cannot inspect a private agreement, decide ownership or certify that a seller has the rights it claims.
