Hi there,
The answer is no. Even if a model is available for free, it is still protected by the copyright law. Quite often models found online for free are actually stolen and reselling such model or using it in your own model will result in copyright infringement and breach of our Terms and Conditions. If such model will be reported to us, we will suspend your model, in case of multiple or repeated infringements your account will be suspended and you will not be able to use our service in the future.
If you have any other questions, please contact support@cgtrader.com.
Kindly,
Austeja from CGTrader
