Create Constellation Mod (1.21.1, 1.20.1)
Create Constellation Mod adds a skill tree to Create and locks recipes until you unlock them. You earn EXP by crafting, turn EXP into points, and spend points on items. The tree looks like a solar system, so picking your next unlock feels like flying through space. This mod gives Create the step-by-step progression it was missing.

Features:
- EXP From Crafting: Crafting things like a shaft or cogwheel in a mechanical crafter gives you EXP.
- Skill Points: Every 150 EXP gives you 1 point to spend.
- Recipe Locks: Machines will not run a recipe until you unlock that item. Your items are returned and nothing is destroyed.
