it looks great. If you haven't tried MAST, you might want to look at it. That way you can place prefabs instead of just models, so everything is already scripted before even being placed.
Very impressive. Bc i know Unity have SNAPS but it only works with their own blocks so as i'm hardly working with your blocks, Kenney and the other friends, this will be really helpful. I just installed it i'll check it out right now ! Thanks very much for this !
