Upper body - Jiggle test

Upper body - Jiggle test, originally uploaded by James D Thompson.

Just added some animation to the upper body chest control to see how the muscles jiggle.

Here ive added some custom jiggle weights so they all don't act the same and they act how the should compared to there real life counterpart.

For the belly ive also added a muscle which acts as the overall volume of fat for the chest that will jiggle as you move so this is an area where you can use muscles for non musculature deformations. for this i attached the muscle from the bottom of the spine to the top between the arms and giving this a higher jiggle weight means it jiggles and acts like a large lump of fat. Then when painting weights ill only add some slight influence of this muscle so there will just be some subtle fat jiggling. If this was an obese character i could give this more jiggle and paint more weight to this muscle so the skin jiggles like there's more fat.

Other ways of adding extra movement and fat is by using the sliding weights and jiggle weights when painting weights. With the muscle system there are several different typed of weights to paint (as apposed to 1 when using the normal skin cluster). The main one is the sticky weight which is where the skin will stick to the bone/muscle object (similar to normal paint weights) then there's things like sliding and jiggle weights which allow the skin to slide (if you bend your elbow the skin will stretch and slide across the bone) and jiggle weights alow the skin to droop and jiggle when moved which gives the illusion of more fat.
