Free accounts rig three creatures
A free account can now rig three creatures instead of one, and at the limit the studio offers to rebuild one you have.
A free account can rig three creatures by hand and preview every animation in the editor (it was one). The three are for the life of the account: deleting a creature does not free a slot.
To try a model again as another body type, you do not need a new creature: open it, change the body type on Setup and run Guided rig again. When you reach the limit, the studio lists your creatures with a ↻ Rebuild button for each.
Also: once your rig is saved, the editor tells you how to get the files, with the unlock price, and opens the packs right there.
