 Hi

I have few questions about animation:

1. Is there a way to change the default interpolation method so while recording a keyframe to set for example custom bezier curves and not to change them later?

2. How can i set a character to not perforate the floor with his legs?

3. Is there autorecord option in workspace side?


Thanks in adavnce

Im not sure about the beziers,


You can use IK locks for the Feet


There are 2 auto record options in Work Space, One is record phy sim and the other is for making recordings of your workflow.

Currently there is no way to automate the stopping of feet going through the floor. The usual way is to place the feet using either IK or FK, and manually ensure the feet don't penetrate the floor. Bear in mind that IK movements when animated move the ik handle in a straight line between the 2 keyframes, but FK moves the joints in an arc. Keep these movements in mind when setting keyframes, and check the entire animation often to ensure no further tweaks are needed and you should have no problem.



It would be nice to have a floor constraint and it is something that has been requested. But bear in mind that for example Blender does has a floor constraint, but in reality it only works with FK and not if there is a IK handle involved. Since Legs are normally animated using IK this near enough makes the Floor constraint of little use for legs (within Blender, as an example)


Perhaps someone may be able to link rigid body physics properties to bones as a possible automated solution, but as yet I am not aware of anyone testing this theory.


Hope that helps

If your character actor has physical properties, the skeleton will not fall through the floor if the floor is an polygonal object.
