Hi,

I can highly recomment trying out Clayxels (https://andrea-intg.itch.io/clayxels). I built all enemy models for our game RoboBlast and using it was ... a blast! :D

Clayxels allows you to quickly iterate on your ideas while you don't have to worry about importing as you model directly in Unity. A perfect fit for game jams imo.

Also check out our game if you want to see the clay creations brought to life.

Keep creating!
