Kh4rn 08-27-2006, 11:56 PM Hey guys, ive been experimenting with creating muscles for my character, but it seem i must be doing something wrong.

my skin is not accurately following the muscle. when the muscle scales on its Y axis, the skin does not react to it.
the muscle was made of a bunch of linked xforms, 3 to be exact.
does anybody know how to fix this, or has any links to a good muscle rigg. just trying to eperiment with it.
thnx

Hi Kh4rn sorry ,
my english is not good ,but i'll try to explain more clearly
first ,i wonna to say something about your way,this way is not the good solution ,
because,
first of all, it need more thing(modifiers,splines etc.) to make one muscle,and for the
complex muscle setup it will slow your rig.,).
you can make accurate muscle this way ,but it need more setup.
so i wonna to show you the easy way:
1.First create your muscle mesh.
2.go to Character>Bone Tools>Object Properties
there, check the "Bone on" ,and under the "Stretch" Parametr select "Squash"
3.create little bone and pose it to the top of the Muscle,and rename it "tip bone"and link it to the muscle
4.create two Point Helpers: Bottom helper,Top helper.
align the "top helper" with the "Tip bone".,and pose the "bottom helper" to the muscle's bottom.
5.select "Muscle" add "Position constraint">Bottom helper
6.select Muscle add "Look at constraint">top helper(here you can change upnode forom "World" to "Bottom helper")
7.Select "tip Bone" and add Position Constraint>Top helper
ok,your muscle is done.:)

First off if you are skinning to this muscle the size and shape of it make no difference what so ever. If you are using Skin wrap then it will. Weighting to this muscle bone will change the way that it affects the skin. If you don't want the muscle to appear to be passing out of the skin then either add mode weight to the muscle bone or make it smaller.

thanx for the comments and the help.
so what your saying is that to use this method of muscle rigg, it is better to use Skin Wrap rather than just Skin??
can i use both?
thanks Sarxan for your explanation, its a lot simpler then what i was doing, thank you very much

i redid the muscle. the way Sanxan sugested and its a lot better.
now the problem is the linking.
ive tried position constrain the point Nub's Point helper to one of the twistbones that didnt work,
in the picture it was done with the reaction mannager , the master being the CTRL Hand x-position and the slave beain the point helpers x-position, it works , untill the arm goes forward,
the muscle apparantly stays buldge.
any linking suggestions??
thanx guys
On the Max 8 disc in the samples folder you will find Maxine. I created her for Autodeskm you can see how I have used muscle in that rig.
