Re: Envelope mesh jumping

sorry for the newbie answer, but are you sure all weights are normalised?

 

 

 

a total of 100% weight assignment to the total of all bones. No more, no less.

its easy enough with the weight panel, as long as you keep the normalise check box on.

 

you can check this easily by moving your skeleton way off into space.

if there's points remaining close to the origin, creating spikes, then they're less than 100% weighted.

if there's spike going further away than the skeleton, they would be more than 100% weighted.

 

and you can solve it easily enough too:

select the offending points, make sure the normalise check box is turned on, and assign 0 weight in add mode to some bone. that should normalise the weights. you should see the spikes immediately jumping into place.

you can also play around with the smooth brush.

Subject: Envelope mesh jumping

I think there's been a post about this many a time before......

 

I am enveloping my mesh and certain bones are making some points on the object jump - some a slight movement shift and others massive movement.

 

I've tried setting ref poses under the envelope tab.... I'm confident that it's a bone thing(Tried freezing the mesh  - tried extracting polys).    I'm particularly frustrated as I had this problem origonally after butchering a previous setup fropm another scene.  With no sucess fixing that I rigged again and STILL getting errors - nowhere near as bad as before but still f***ing up.

 

 

 

HELP!!!
