OH gods I can't imagine how frustrating that'd be. I've done some very basic 3D animation and rendering took FOREVER, so taking forever AND having a problem is just a punch to the kidneys. Alas I couldn't tell you how to fix that issue. XD
Nothing wrong with purchasing assets. You paid for them fair and square, you own them. That said, crediting the asset's original creator never hurts if you're worried about credits at any point. Ah how fun! I'd considered doing that when I was younger but, I ended up becoming an editor instead lol. (Surprise, surprise, the derp who hands out writing advice all over the place is an editor. That's a shock worthy of Luke's Father! XD ) Ah Maya, I've ogled it but I had to choose between it or a new Wacom so, hahah obvious which one won out. Still, it looks like a lot of fun to use. (I got lazy and downloaded Blender since it's free...and I'm lazy). Oooooh that sounds awesome! When you finally do, you've gotta post your results!
No problem, it was Free when I downloaded it so it has to still be free. Ah, I don't have an iPad one but, hahaha I only use my iPad for reading books anyway and nobody wants to watch that. Lol.
HAH oh gods, if Khloe had access to a credit card her father would flip his royal shit. HAHHAHA, I can just imagine the rage on his face at the thought.
