No Country for Old Men Sprint #10

 For this sprint I worked on just the money case rig.   The money case rig is built to be simple and rigid.  It is fully FK functionality.

To start I simply placed my joints in the geometry in the areas that need to bend and move.

I also organized my hierarchy with a naming convention.

From here I used my controller generator tool and created some controllers for my rig.  I also colored and shaped the controllers around my geometry.  I also added constraints from my controllers to the joints for simple functionality.

Then I worked with skinning.  I added a geodesic voxel bind method and began to see how the rig moves and what needed to be adjusted.  After skinning I ultimately added some more joints and a few more controllers to get the movement I was looking for.

Once I skinned the geometry to the joints I went through each controller and locked and hid the transforms and scale.

After cleaning the money case rig I exported and brought it into UE4.  I ran into an unexpected problem after bringing this asset into UE4.  Some joints were added and the root joint was taken out of the rig.

To troubleshoot the problem I went back into Maya to search for the problem.  After opening Maya to my money case file it crashed and corrupted my rigging scene.  I did get my scene to open but I found a broken rig with all of the controllers locked.   To get the controllers to work I had to unlock all controllers.

I decided it was best to start with a clean file so I went back into a previous save I had worked on and went through and began to check for what could have caused the error in unreal engine.  I checked the geometry and cleaned it out of any values it had in the transforms and scale.   I found that a few of the pieces still had values and history.  I then checked each joint and re-skinned the geometry.
