If you have a client that commissioned you to model an object or scene for them, then they should have opened a Project on CGT using the "Hire Me" button. Once they do that, they can submit the payment they want to make and you will get notification of it. You have to approve that amount, then CGT will hold the client's payment for a period of time until the project is finished. Once the project time expires, CGT will put that amount into your payment account, minus their percentage, and you will be paid for that project in the next payment cycle. It will be put into your CGT account earnings for the month. If you want to be "instantly" paid, then you really shouldn't use CGT to communicate with clients. In fact, you may get a warning if you do a private commission on here without using the Hire Me function.
