hello guys.
i have a problem here with blendshape and set driven key....

fig1 shows the arm rotated in the Y axis at 90degrees...i added a blendshape/setdriven key combo that will deform the shoulder armpit area when the joint rotate in this manner...

everything is nice and perfect until i rotated the elbow joint(i also have a set driven key there that activates the blendshape when ever it rotated in x90 so the elbow dont look ugly when the joints move)...the morph target of the elbow somewhat affects the morph effect of the shoulders as well(fig2)...i tried removing the vertexes in component editor...but i cant find them is there a way to fix this? in max,u can apply the morph/angle trick locally to a given group of vertexes...is there a way out of my problem? please help me.

Well, ok,

Couldn't you modify the elbow blendshape so that it doesn't move any shoulder vertices?

And also, there is a way to only morph parts of your model just like in Max (sorta).

If you select part of a model, then create a Set (Create > Sets > Set) you can then morph only that Set if you want to.

Example:

1. You could select your shoulder vertices and create a Set called 'Shoulder_Set'.

2. Then select your elbow vertices and create a Set called 'Elbow_Set'.

3. Then you make the two blendshape targets.

4. Then make each target a Set, (Eg 'Target_Shoulder_Set and Target_Elbow_Set)

5. And then use the blendshapes to morph the Sets.

Get it?

hi!

i have done a character this way and i have no problem like you.
i think that the prob on your model was, that you didn't painted the skin weights before making the blendshapes!!!

don't shoot me!!! this is just an idea. :)

bye
