thanks Dan, i just dragged Jordi thru to have a look and it turns out to be a
compound scaling problem, to sort it out
would involve a lot of reworking of the animation/rigging etc.....
sorted it by creating a second set of bones, constrained to the originals and
using this as a secondary rig for the new geometry

Hi Adrian..
To avoid this happening you need to envelope the second object while the
skeleton is in the pose that you enveloped the first object in, I do this by
saving an action for the reference pose but there are other ways..
If you've already animated your character and lost your reference pose then
you can save the weights out for the character, freeze the mesh, then add an
envelope again, and load up your weights again.. After doing this you should
find that the second mesh should envelop fine
Hope this is of some help
Dan

Subject: basic envelope madness
ok, i never claimed to be a character TD, but i have a problem i'm sure is
a bit more
complex than it seems on the surface.....
the manuals have been their usual 'helpful' selves...so it's down to you
kind souls who may, or may
not exist purely in my imagination
example:
i have a skeleton, and it has an envelope (a cylinder) the skeleton is
animated and so far so good....
the skeleton/cylinder assembly is parented to a null, which in turn is
under a Model.... this model has been moved away from 0,0,0
now i have another 'half' cylinder i want to ADD to the envelope (kind of
like adding a hat to a rigged/animated character)
i select the 'half' cylinder and set envelope and pick the bones, and the
'half' cylinder 'flies away' !?!?
it seems slike NO combination of parenting/freezing or ANYTHING will allow
me to add the 'half' cylinder to the 'mix'
without it flying accross the known universe...
if anyone has any ideas, shout up... or feel free to download this 166Kb
