Joint pops

Recommended Posts

I realise this is a bit of an open question, for which my apologies.

I'm working away on a sequence were the figure rises to standing, turn, shifts weight and settles. Thought it was ok until I noticed some joint pops and went to look what was causing it.

The interpolation is set to spline. There is a four frame space between one pose and the next but, as you can see, on frames 16-17, there is a definite pop in the joint.

 

Leg_pop.mov

 

Is there a way around that ?

The key is on 15, the pop on 16 and 17 and the next key on 20.

Its not too big but it is noticeable and, if anyone has a suggestion as to cause and possible cure I would be very grateful.

regards

Ps

Just tried smooth, that seems to ease it if not remove altogether. Is that the answer ? ( asks he foolishly )

You could also use an exponential decay setup to get "soft IK"...there's a tutorial for that here.

 

There is an example of this in Squetchy Sam. You can set an arm or leg softIK limit to something like 98% to get rid of the problem.

 

Hope that helps.

The tutorial is also located here with the finished model and subtitle file included.
