Creator royalties

I have seen a lot of information about this thrown around and even a DAO proposal about it. but at the moment I am under the assumption the only money earned from wearable sales is well… through the mana marketplace.

but what happens if sales happen on opensea, who gets the funds from there? do we get a royalty percent on sales from that side? wondering if there are any people who can shed some light on these things for me as a lot of internet info and forms seem to be a tad out dated as DCL moves forward.
