about squash& stretch

there are 2 simple effect but i dont find the way, can anyone tell me?

1) how do this style Squash and stretch effect in Messiah ?

2) how messiah do path follow animation?

thanks for any advice..

two ways

the easiest one is to have a muscle bone and a target to aim at. muscle bones automatically squash and stretch.

the other is to add the x and z channels to this expression: 1/sqrt([Skeleton_Bone_1:zscale])

path follow animation(meaning it lags behind another object at a distance) uses this expression:
if you want to use a frame offset instead of a distance offset, use:

JoeCosman, thanks for your reply

your tow solution is usually right work for squash&stretch. but I think I don't say it clearly,

1) I want when Squash it, the box mesial part will bulge; Stretc it, the box mesial part will shink
. like attatched picture showed.

2) eg, I have a motion path curve, I want a box move along this curve , like this style path follow, or other names. and how can i achieve it?

thanks a lot

On lightwave, just use endomorphs do get this result!

ohh... yes, it's the simplest way to get effect, thanks for your hit.

isn't it any direct way to get it?

Have you tried the muscle bones or Joe's expression? It doesn't get any easier than that.

Or are you referring to the curves of the objects when squishing?

I think he's referring to curves.

so.... two ways, again.

first is a morph target. model it squashed, or stretched, and the negative value will give the other result.

second is parent a bone to the root, with a metaEffector defining a weight falloff. use the same expression 1/sqrt([Skeleton_Bone_1:zscale]) and add the second bone's X and Y scale.

the metaEffector will define the curve bulge, and the bone will control the amount of scale.

you can also key this by hand, too.
