GAME FUR HAS NEVER BEEN SO EASY!
Fur Factory is a fun and easy Unity tool to create great looking fur for your game! With a single click you'll be able to spawn multiple hair clumps onto your character. You can comb it, cut it and even use hair spray to shape it however you want!
The fur is automatically skinned to your character, naturally deforming with the base skin.
