Human animations FK or IK ?
Monday, March 7, 2011 - 11:17
I have started to look how animations work with blender, and I need some advices. I would first like to make a stance/idle animation, then I will try walking.
- Should I use FK, IK or both ?
- Should I start learn animating as mocap kinect software should be soon available ? :P
I use IK solvers for the legs. For the arms, I use auto-IK to create the general pose and then tweak it with FK.
Here's an endlessly useful tutorial for animating humanoids, simple enough for a beginner: http://wiki.blender.org/index.php/Doc:Tutorials/Animation/BSoD/Character...
IK! IK! IK! I can NOT stress this enough.
I have to reboot a game because I didn't use IK - now I wish I did in the first place.
I'll be the contrarian and say: it depends on what you're doing.
I use FK because I'm rendering sprites that are about 60 pixels tall, with walk cycles that are only 8 frames. FK is easier for me to work with in this situation.
