Hello Can I use TurboSquid models for a commercial game ? I thought it was obviuous but there is no evidence in the web site Moreover you can purchase the same models at the same price also from the artist web site but purchasing conditions may be different

The people most likely to have a 100% accurate answer to your question are Turbosquid, so the logical thing to do would be to ask them.
