The challenge was a character that looks like it’s thinking about something. I went for the standard MAX rig here (well known to anyone who’s tried to use free animation rigs no doubt). The blender version of the rig I have is not great, but it works. Rendered using cycles as well, so it’s a smite grainy because I didn’t want to render for 5 hours.
The challenge was a floursack falling, either a looping fall or landing on the ground, I went for the latter of the two.
Challenge was a character blinking. I tried to add a bit more emotion to it as well, as just having blinks on a 3D character would be a bit dull.
Challenge was a brick falling off a shelf.
Challenge: A waving flour sack.
