Final animation
Though compare to body mechanical I’m more interested in other aspects of a 3d animation such as concept design, environment animating, texturing and VFX, it is still nice to have the basic knowledge about body mechanicals.
Points about body mechanicals:
I think have an understanding about physical limitations, anatomy, and principles of motion is very important when it comes to the creation of convincing and natural animation.
Personally, I think 3d animating has more limitation compare to 2d animation, which made traditional 2D animation look more interesting. I think that is perhaps why most people in the industry nowadays choose to make it blend more with vfx and 2d animated effects. Maybe in the future as the development of 3D software there will be more possibility in 3D animation.
