I’m wondering should I need a pattern key and what is the feautures with that? I mean I don’t use any custom vehicles or custom clothes.
Everything is free and you don’t need a patreon key if you stay below 10 players on your server.
If you go above 10 players, you will no longer be able to use custom clothing as long as you don’t have the “Argentum” Patreon membership.
But you will still be able to go up to 48 players without needing a membership (you will just lose "custom clothing).
Tl’dr:
If you are fine with not having custom clothing and “only” up to 48 slots, you don’t need to pay anything.
The first tier is “argentum” and allows you to use custom clothing at any playercount up to 64 players.
“Aurum” ups the playercount to 128 and “Platinum” up to 2048.
There are other benefits but my guess is that these are the most interesting ones.

what about cars?
Cars don’t require any Patreon pledges, the only two things that you must have a pledge for is custom clothing for 11+ max players and to go above 48 max player slots
