Hello!



I have really problem width (eye)lid bind. I wrote step by step what I do and what doesn’t work.
In first I create clusters for vexters:

Then I put weight’s value’s and I put the pivot of the cluster exactly in eye center(pivot).

Now I parent the clusters to joint (I try parent to different joints but effect is the same).


http://www.tibik.nazwa.pl/Grafika/Forum/prent.JPG (http://www.tibik.nazwa.pl/Grafika/Forum/prent.JPG)

Then I give key set to eye.RotateX and cluster.RotateX, When I don’t move a head everything work great, when I move eye aim the (eye)lid move very nice. But! When I rotate the head (simple to back) the cluster move ok. But the skin of eye move wrong, not like when head not move. Why?

P.S

it just normal parenting problem... it call double transition...thing,,

try select your cluster unprent them (in bind pose) , hit 'ctr+g'(make a group),
move group's pivot to head joint. then select group nod and parent to head jont..

good luck

your problem may be to do with the ordering of your skincluster and the cluster in your inputs section. I think the skincluster has to be below the cluster in the inputs of your skin mesh. you can edit the ordering by right clicking on the mesh, selecting inputs and you should get a list. You can middle mouse drag the skincluster above the cluster in the list (or it may be the opposite way around)
hope this helps but In all honesty I've found just leaving the cluster location where they are in the bind post, creating a set-driven-key for the cluster to a control curve and parenting that to the head joint should work well - this way you leave your clusters alone but can still control the blinking from the control curve :)

Hi!



Thanks for answer!

The inputs is good. I try blend deform the eye’s: I duplicate the original head twice and I model a up and down lid, then I try add the new heads to the blend, but I have new funny error, when I put some values for up/down lid’s then no lid move but head move up! 8-/

Could you tell me (step by step) how using a curve to control the lid? I be really appreciate.

Really Thanks for help!

clusters are most likely the best way for getting a solid blink on a characters eyeball. Blendshapes wont do the job really as the mesh will move through the eyeball unless you create an inbetween blendshape.
As for the head moving - not sure why that is - can you not just post up some pics or the scene? would make life alot easier ;)
