Just playing this weekend exploring Houdini Crowds. The character is from Autodesks Character Generator, animated in Motionbuilder and exported into Houdini as an FBX.

Interesting!
Why some characters seem unstable after falling on the ground?

Just thought I'd change the subject line to avoid multiple posts.

I just watched the Instancing tutorial on the SideFX website and thought I'd take a shot at a Lee Griggs style render, and wow, is it tough to even get remotely close to his artistry.

Well done. It looks really nice. I just started play.

I started an environment for the little monsters to run through before they get to the mud pit. I'm probably not going to have the render power to render an HD animation. This frame took 2 hours on my machine.
