Hi,

I am working on a hand tutorial and am having an extremely difficult time posing multiple objects in Mudbox 2011 (Win7 x64).  Specifically, I am trying to pose the fingers + nails and can’t seem to get the Mudbox weights tool to paint consistently on a specific nail.

The initial index finger pose from the knuckle proceeds without issue:
- I create a joint and weight the index finger on the hand (object 1) from the 1st knuckle to the finger tip.
- I select the weights tool, set it to 100 strength, paint only the index finger nail (part of object 2).
- I select the pose tool, orient the camera and position the index finger + nail, rotating from the 1st knuckle.
- I select the create joint tool and commit the pose.

The problem occurs when I go to pose the 2nd knuckle on the index finger.  I follow the same procedure (except on the next knuckle up) but when I try to paint weight on the finger nail I am unable to.  There is no color feedback even though I see the nail geometry layer appearing as active in the layers palette.  I am able to mouse over the nail geometry to activate it and flood influence but this doesn’t help because it fills all the finger nails and I am unable to ctrl-paint out the influence on the every other nail except the index.

I conducted multi-object posing tests using the Mudbox dinosaur mesh and two spheres and the results were very, very unpredictable.  While my first multi-object pose would usually go without issue, subsequent multi-object poses never allowed me to re-weight all three objects.  Sometimes I could get two, never three.

The only solution I have found is to delete my fingernail geometry and undo.  Somehow this allows me to paint weights as expected on individual nails.

I have tried uninstalling/reinstalling Mudbox, tried the OSX 2011 version, importing each piece of geometry as a clean OBJ, looking online - no luck!

Am I missing something?  Any help wold be appreciate as I am very frustrated...thanks,
