Take a look at this site: http://artblock.ru/html/downloadmodels.htm And then take a look at some models on the assetstore. Especially the Cartoon Truck with damage model. "All these models are free, you can use them as you wish. " But does that mean you can sell them for money ? The site seems to be a bit older than the realease date of the assets. I´m just wondering that no one else see this before.
