Blend Shape on eyelid?

[user_deleted]

Hi Folks

I maked joints to control almost all expressions of my head. But in the EYelids i done blend shapes. So when i moved the joints of my eyebrowns, the eyelids overlaps the eye...Can i do the eyelid with a better tool intead of blend_shapes?

I taked a picture www.vsnet.com.br/d2r/test01.jpg

thanks the attention

meny dfferent ways but i usualy like to use clusters (the same as using bones btw.) and then rotate the eylids around a central pivot incide the eye, if i now need seom additional controll i aply a latice on this the use expressions to drive the inner parts of the eye slower to make it move like one.

Then if you need slider controll just make the conrolling atribute part of a blend (the blend can hamdle pretty much any geomety even bones, altough it could cause them to move in unnatural manner but rotation is pice of cake).

hmm...I, like Jooja, think clusters can be useful on certain types of eyelids. Generally though, I prefer to use mainly blendshapes for entire faces. I only really use joints to control the lower jaw and orientation of the head...though obviously certain designs and effects may require more. What I usually do is to make small bmp images of each blendshape of each part of the head and write a new blendshape editor that includes the pictures. This way I can have hundreds of acurate and good looking facial expressions controlled by sliders that are very fast to animate. Using lattices and/or skeletons to control faces can be very messy and time consuming, when at the end of the day, you could use that to aid your making of a blendshape and therefore not have to let the computer do all these calculation-heavy deformations on your object whilst animating.

yeah, but its not a do or dont thingy you can have bones that you can animate directly and then a bunch of blenshape sliders that controll the bones, thisway you can setup like in a blendshape situation + You have the option to something radical...

But ist more costly and time consuming to set up offcourse

It sounds like you need an 'In-between' Blendshape so it doesnt intersect the eyeball. Had the same problem myself recently.

Just dupe the object when it intersects the eye, pull out those cv's or vtx's, and open the Options for Edit-Add-Blendshape. Click 'Add In-Between Target'. The Target index refers to what existing Blendshape Shape you want to add this too, and the In-Between Weight is when you want that InBetween to happen.

So, when you've added it you have a Open eye at say 0.0, an inbetween Shape at 0.5, and a fully closed eye at 1.0. All controlled through one BlendShape slider.
Neat!
Thats been in there for ages and I never knew about it.

good luck!

actualy eylids can be done with a number of (that drive eachother) clusters that pivot around the precieved ceter of the eye and the (if your eye is not round), pushed up to match te actual shape.

Try to change order of transformation - skining after blend Shapes.
