I'm currently tasked with designing a small HTML5 game. Having done everything by myself so far (3D models, codebase, game design, etc) I'm now at a point where I'm running out of time.

I've less than a day to animate and bind everything together. However, that's exactly my problem.

I was under the naive impression that everything would be easier if I went with pre-rendered 3D models. However, I didn't consider the most difficult part. Animation.

After having spent over an hour trying to figure out messiahStudio, I figured it's time to ask for outside help.

Is there any easier solution to 3D animation than 3D rigging? What I'm basically looking for is some sort of tool that allows me to simply grab and move/deform select polygons.

It doesn't have to be as life-like and accurate as rigging, just efficient enough.

Were the circumstances any different, I might just learn how to rig. But that's sorely out of scope right now.

PS:The models were created in Sculptris but are fairly low-poly.
