This year I made a switch to Blender 3D from Maya. Quite simply I was tired of looking for ways to make maya talk to external renderers just to get the look I wanted. Now I'm happy to say I'm glad to be learning Blender's other superb built in features too.
I was initially attracted to Cycles, Blender's unbiased renderer that is GPU enabled. Whilst I don't have a GPU enabled pc yet that is on the list for 2014. I am very excited to see the results of what I plan to shoot and matchmove, combined with what I can model and render in Blender.
My major headaches currently (as blender is known for its interface quirks), are getting materials looking the way I want, and understanding how, and becoming comfortable with all the rigging and animating tools.
Also I wonder if its possible to rig lattice modifiers with splines like a circle.
I could in 3DSMax....
