Blender 3D--Muscle Test

Just playing around with using the Maintain Volume bone constraint to flex some muscles. Create a separate vertex group for each muscle and in Weight Paint mode, paint the part of the muscle to be deformed. Give the bone a Maintain Volume constraint. You can use IPO drivers to control so that the rotation of the leg bones drives the scaling of the muscle bone.

T-Rex model is by Cyberchinchilla and is available at Turbosquid. I reworked the shape of the leg.

ETA: After seeing Juan Bouza's BlenRig, shape keys would probably be a better way of doing it.

Brilliant job, how did you set up the rig?

@conormcm Thanks for the comment. The dotted lines show where connecting bones were deleted to clean up the view. Shape keys are still a better way to do it.

@SteveS3D Hi Steve, thanks for the reply. I am still experimenting with blender, I have used shape keys to make various mouth shapes, but, are you able to set up shape keys (for example, for muscles contracting and expanding) that are effected/controlled by a bones movement?

You did an excellent job my friend ! Thumb Up !

i have tried doing this myself but when i added armature to use as the muscles and all my model went kablowie. so i dunno what i did wrong or whatever but i am open to suggestions. i REALLY wanna be able to do this in blender but so far my models come out stiff and no muscle, skin deformation or anything. looks so FAKE.

how did you get the armature to allow the ipo driver upon itself? I can't seem to get blender to do this for me.

Nice video.

Could you make a video tutorial showing how to do this?

I am afraid I don't get it from the description you wrote. Shape keys could be used but I am interested in other ways of doing this :)
