Hello,

I imported a robot in fbx format in CC4 and I use the"Characterization" function to adjust the bones of the robot.

I have a problem with the rotation of the thumb bone of myrobot. In blender the direction of the axes is correct, so in CC4 the axis ofrotation remains fixed on the axes of the world and not on the local axes. Therotation of the thumb is not done in the right direction. Can we force CC4 towork locally rather than on the axis of the world during animations? How can Isolve this thumb animation problem of my robot?

Hi...

Have you been through the two tutorials below? These cover general characterization and also the Bone Manager which should help.

Hello,thank you foryour quick response. I renamed all the bones to allow thesymmetry. I followedthe tutorial. I linked all the bones in the"Characterization" tab. Ipositioned the thumb in the right place inthe T position. And I activated thecharacter. The thumb still doesn't moveproperly, and tilts at the wrongangle. I still can't find the solution.

Hello, I took over all the settings of my bones in blender with the different objects so that they all have the same axes of rotation. I always encounter the problem in the rotation of the thumb which goes in all directions. Do you have a solution or a reference of a tutorial to my problem ? I thank you in advance for your response. 

I do not think you can do much there for the thumb other than manually animating individual bones.
There is a slight tilt by Y (which actually should not be there) when you workout FK with thumb root.
No human can tilt second and third finger bones (not to mention robots) :w00t:
But while it's not noticeable much on human hands, it certainly is on robotic.

So again do not use ready to use gestures or FK from the finger root (at least for the thumb), rather animate/tweak 2-nd and 3rd bones individually.
(that is given fingers mesh is precisely aligned with bones).

Thanks for reply. I took over all my modeling process in Blender being new to this software. I did a lot of testing and I realized that it was very important to properly reset the scale, position and rotation in blender for each object as well as for the skeleton. Now when I import my robot into CC4 everything works fine I just readjust the thumb closure angle which is too open for my taste. Thanks for your help.
