I have to disagree. I tried to sell a few of my packs via TurboSquid but I get much more sales via our Dexsoft-Games page. The fact that TS wants to have 50% is also very bad. Most partners I know (GarageGames, Darkroomstudios, Gamebeep) take less.

Because of that I stopped to upload my packs to TS. It is just waste of time if you get only a couple of sales per year.

Another problem with TS is the huge amount of content while 99 percent is pure crap. This is just spam, like a really big pile of garbage and you have to search and search until you find something good.
They even offer a simple texture for 50 $ or just a wall, a cube for 50 or even 99 $. This is often funny or crazy. They simply need a quality management.
