I LOVE to use blender. Maya and Max are shitsticks vs blender.
Blender is Open source. That means: NOONE wants to clean this shit, everyone's just adding addons.
Did you try looking into the source code of your fucking .blend file?? The fucking STEPS are saved! For SOME fucking reason.
When you import a named .obj model, and rename it in blender, it doesn't fucking matter, the original name is still saved in the .mtl. That means if you try to do anything with it in the engine, you don't know what kind of name you should address.
Rigging SUCKS in blender, it can't be used for anything. If you try to put a rig into an engine and try to move the bones individually per code, you're fucked. This thing is the most buggy mess I've ever seen.
Yes Max crashes. Yes the Interface is a piece of monkeyshit. Yes ZBrush controls suck giantic horse schlong.
But the files are usable. The Files blender puts out are good for one thing: to be opened in blender.
