I've been working a lot in Maya recently as well as 2D. At the moment we're just covering the basics such as; making a ball bounce, without squash and stretch, and making a ball bounce with squash and stretch. I'm currently animating a ball and chain along a piece of wire to illustrate movement and weight.
I'm going to playblast everything later and upload it onto here :)
I find Maya quite challenging, but I enjoy every second of it. It's such a nice program to use. I'm going to have a play in Mudbox as well later :)
