[Bf-committers] Concept bug with Shrinkwrap(projection)+armatures

Thanks for your comments. However I'm not able to reach a usable
solution even with "nearest surface point". I've tried everything,
without succeed. If you want to try I've uploaded a simplified version
of the eye rig: http://www.pasteall.org/blend/14049 . The "target" bone
should keep the eye looking at it. Then you can scale bones
eyeball_internal and eyballe_external to change, independently, the size
of the iris and the pupil.
Anyway, I think we both agree the "project" mode for the Shrinkwrap
modifier is not working as expected and "using projection mode is not
such a good idea, it has many many problems with rigged meshes. ". So I
guess it should be fixed/improved/whatever. Is there a proper way to ask
for this fix? I mean apart of a bug report or posting the problem in
this mailing list ;)
And about the complex deformations " but what if the face of the monkey
was also deformed by other bones or shapekeys? ". I guess that is simply
impossible to do right now. Maybe in a few years...

In that case not even a change in the axis object would work, and it would require a kind of per face axis selection..
