Pretty sure the 2D method is easier for most people.
Sadly I'll have to take the 3D route due to having to make a 3D system for the fake 3D thing the 2D system is using (easier to animate 2D with 3D in this case anyway, since it's imitating 3D anyways).
<s>You never specified what kind of cat, so I may or may not get creative</s>
In all seriousness though, I can't make modells for any program, hence I'm making my own program. Unless you have like at least 3 old3DSes, and a new3DS.
But really-
I’m look at online commissions and they start at like $200-
I’m both really cheap and I don’t even have that much to spare right now!
Hmm
Well if I manage to learn it- I’ll help ya out >:3
...unless you're like me, and spend weeks and months trying to make it as perfect as possible before attempting anything...
