A few questions about (public) UGC

A have a couple questions that don’t seem to be answered, so I’m just going to ask them here.

  1. If you upload UGC, is it automatically given to you? Does this apply to uploading through groups or games?

  2. What is allowed in an accessory? Things like welds, constraints, and attachments? (so if i make a propeller hat, can i use hinges to make it spin?)

  3. Do premium players get a reduced price or no fees when uploading?

I might have more questions later in replies, there doesn’t seem to be a faq or blog post about public ugc
