As of now, our plan is this:
Custom player models:
will be automatically downloaded for you (you do not need to be subscribed before hand)
can be turned off at any point
can also not be automatically downloaded and you can manually subscribe
can be filtered out by tags (i.e human, non-human, etc.) and will be appropriately tagged
cannot have NSFW content as it is against Steam Workshop rules and will be removed
can also be filtered out by their upload date, so if you’re worried about seeing something NSFW, you can filter out brand new workshop items to avoid that before we get to them
will not be in stores to be unlocked, they will be free
cannot be used in competitive Game Worlds (ie. Virus, SDNL, etc.)
This is all subject to change, but this has been our plans internally for months now.
