Hi
The necessary explanations for this are available on the homepage of the site. but generally speaking, there are 3 different methods for this.
1- You can upload your own models to sites like cgtraders and wait for them to be purchased. this can happen at any time. It may never be bought.
2- Sites such as cgtraders have project-based systems that bring customers and freelancers together. Here you can bid on people's project requests. If your offer is accepted, the fee will be sent to you directly by the site after completing the project. (after deducting some fees)
3- You can participate in the competitions and if you win, you can earn the competition fee.
for this you need to have an approved online payment system. You need to enter all the necessary data into the system to confirm the payment method.
If your payment method is approved, cgtrader site transfers the previous month's earnings to the online payment system on the 20th of each month.
