It has serious potential, but there's just way too many frustrating bugs, such as:

• when scaling multiple  blocks at once , non-uniformly, the scaling comes out the way you want it, until you click somewhere and all individual blocks get rotated and repositioned slightly. This is extremely annoying when trying to resize custom limbs with a lot of joints.
• The scaling sometimes just does not working how you want it: while scaling on only one axis (i.e. not holding dowen CTRL), the program might decide to scale whatever you selected on all axis. Also, when you are trying to scale a rotated object in local mode, the software just scales it on global.
• Materials sometimes just don't want to apply and you have to restart the app to make it work again. I made a simple object in 10 minutes and had to restart 4 times.

I really enjoy what kenney is trying to do with this software, but I just can't recommend it in it's current state.

if it weren't for the bugs, i'd give this 5 stars. I feel it deserves the 3 stars I'll give it because of how incredibly easy it is to create good looking models with this, or could be rather...
