I want to change the small shop icon to a large circle so the players have to actually find the chest, is this possible?

Not by config, but you can edit the .cs for now:

genericMarker.radius = 0.1f;

change to

genericMarker.radius = 0.25f;

or higher if you want.

Perfect thankyou, Im also having an issue with the NPC's not spawning

Merged post
