We have a cool unicyclist character who is intended to ride around on his unicycle at all times. He has an idle balancing animation, and a walk (slow cycling) and run (fast cycling) animations as well. Everyone else in the project is bipedal, so I have been using the Locomotion System on all of them, however this guy is not, so I have been using a script based off of the ComplexWalkBlend script included with the Character Animation tutorial.
I can get this script to work easily on a bipedal character, but not on the Unicyclist. He will move around from place to place properly, even changing the direction he faces, but will not animate at all. Even when I force the walk.weight to be 1 and the speed to be 1, I see no animation being played.
I realize the best way to diagnose this would be to create a package and post it, but at this point the project is massive and any package I export from it is equally so. We’re attempting to analyze any issues with the FBX export from max that may be involved with this, or anything specifically asset related. For now I can only offer up the scripts driving it and hope that someone has encountered a similar issue before.
