I was considering signing up to be a vendor but I can't find any information on how it works here. I can see the application but it provides no information on the revenue split or anything else. Where can I find some information?

You can find information here: https://www.renderosity.com/brokering-with-renderosity . There's also a link at the bottom of that page for the vendor policies. 

And so you don't have to come back to this thread if you want to check it out again later, you can find the link here 

Ok thanks.
