View Full Version : delayed update problem.

I don't know why this happens but it is quite annoying. I usually control my torso rotation with a null. In fact I don't like touching any of my bones after rigging is done. Everything is controlled by nulls so when I use the motion mixer, I only use nulls. Nevertheless sometimes when I use nulls to control bones, updating is delayed until I scrub the timeline. What I mean is on most of the nulls, when I rotate or move them, it manipulates the bones in real-time. However on a few of them, I have to scrub for and allow it to update. What is the deal because this makes it very tough to animate.

I dont have that happen. Is your interactivity set to delayed in the options panel?

How do you have your rig set up?

What exactly u do with Motion Mixer ?
If u use weight curve it's work with delay ...

My rigs are set up pretty standard in the legs, absent a knee aligning null. I use expressions to line it up.

The reverse hip bone is parented to a 'Master' bone which is the center of the entire rig. Turned opposite that is the 'upper_master' which is the parent to all of the bones in the upper body. The hierchy is then:

[upper_master]
__[abs_L]
____[abs_H]
______[chest]
________[neck_link]
_________|_[neck]
_________|___[head_link]
_________|_____[head]
________[collar_L]
________[collar_R]

'Master' follows the wpos of null 'Body_Master' via expression
'upper_master' is parented to 'Master'

there is a null called torso_control that follows abs_L but controls the rotational axis of abs_L through expression. Thus there is a multiplier effect as chest rotation is expressed to abs_H rotation which is expressed to abs_L. Small motions in the lower abs=large motions in the chest and upper body.

The problem is that torso_control is the only null in the rig that does not update abs_L in real-time via the expression and with no abs_L motion, there is no upper torso motion.

As for the motion mixer, This happens prior to implementation of the motion mixer and I use it for mixing motion and repetitive motions.
