Rotating Foot Wierdness

[Domarius]

ascottk, in Motion Builder, can you try - lifting the left foot upward, then rotate the ankle so that the tips of the toes touch the ground? Point his toe down like a ballerina.

 

I can't make him do it. Every time I rotate the ankle joint, the whole bottom half of the leg raises into the air, and it won't pull down unless I unrotate it. It's as if rotating the ankle actually rotates the knee. Also (maybe related) if it bends far enough, the toes go all weird and scrunched up.

 

In case you're wondering - I'm trying to make him scuff the ground with the toe of his boot, and he just won't point his toes towards the ground.

Something like this?:

 

It looks like the floor contact plane is longer than the foot so the toes never touch the ground. I wondered how to fix that but I haven't had the time to figure it out yet. For the shot I just raised then rotated the foot.

Ahhhhh that explains all the wierd behaviour, including the toe rotation.

When I rotated the foot, the extended collision pushed into the ground, pushing the foot up and thus, bending the knee. And if the foot is no where near the floor, the foot rotates fine.

 

Well allI have to do is disable foot contacts while I do the floor scuff part of the anim.

 

I'll also have a crack at fixing the length of the foot contacts.

I found it, thanks to oDD's vid - In Motion Builder, go to the Editing layout (CTRL+SHIFT+3) and choose hikHandle1 in the Character Controls. The floor contacts become visible and you can edit them.

Okay I fixed them and am about to upload.

Oh, so that's how you fix it. I had problems with that as well, when I was trying to make the death animation where the character falls to his knees.

Glad you found it useful. It really is a helpful feature - once you know how to turn it off and on and correct the foot size.
