Renderosity has a new “How to become a vendor at Renderosity Marketplace” guide page with specifications, links to templates, and a vital little visual guide to how to find the right bit in the UI for the first time…
Note that a new vendor is only allowed three products, until they reach a certain amount of sales. Thus, don’t launch with three small or niche “test the market” products, or you may then never be allowed to list your blockbuster products for sale.
