I sell on Turbosquid and I recommend it, as it is the heaviest trafficked model site out there… I only have a few assets up but I’ve made a good bit of money, as Loopix says the percentage is only 50% of sales where Gamebeep offers 75%... however I have one particular asset on both Turbosquid and Gamebeep… I am selling the asset on Turbosquid for $30 while I’m selling the same asset for $20 on Gamebeep. I’ve sold this asset 9 times on Turbosquid and have only sold it once on Gamebeep. Model sites are a good way to make a bit of cash from overflow art work, if you have stuff sitting around not getting used you may as well sell it. Publishing to Turbosquid is pretty fast and painless too, very streamlined! They are constantly improving things over there too.

Ps. there are lots of other model sites you can sell on too.
