Biasing an averave..

Biasing an averave..

Cheers Raffaele...

I tried using constraints on a 6 bone chain, see I want each bone to be
blendable between an IK chain and a chain with the Spring Op on. It seems to
work fine for the firct 4 bones, then kinks at the 5th, non-comprehende!

I'll try using 2 x 3 bone chains and see if that works, any other suggestions?

Cheers

Jamie

 If you constrain the orientation of this 3rd bone to the other 2 the blend of
the second constrain is going to act exactly like a bias, with 0.5 averaging
and anything below or over 0.5 moving toward one or the other bone.

 

 If constrains are not an option you are then looking forward to scripted
operators and slerping quaternions.

 Afternoon all,

 

 Great to see the new features in 4, soooo looking forward to owning a copy...
anyways...

 

 I'm trying to create a Bias slider for an average of the z angle of 2 bones
onto a third.

 

 This makes the Z angle of Bone C sit in the middle of bones A and B, I need
to find a way of biasing that average through a slider.

 

 I hope I am having a dumb day and the answer is staring me in the face!

 

 Cheers all

 

 Jamie
