I want the muscles of the legs pumping and have translucent properties so to show something is pumping inside. I know I can do soft body or cloth sim but I'm not sure how. I don't know how to pump it after that softness.
I want these marked areas to pump and act like flesh in my scene. I have one year of experience in Blender but still don't know many things so please suggest tips that are beginner-friendly.
