Hi,
I’m using macros in my relation constraints in Motionbuilder. These have a very nasty tendency to be broken (all connections and inputs and outputs missing) once the scene has been saved and the re-loaded…
Does anyone have a clue what’s up?
Yes, this is a bug in the latest version of mobu-
Bugs found in MotionBuilder 2011-
Take order after reordering in the navigator is not saving, no fix currently
Macros in Relation Constraint does not correctly save/reopen if the macro is in any other node but the first constraint created.
Extrapolation for keyframes , doing loops etc, does not save correctly and reopen-Workaround you have to bake/plot the keys on a layer to make for easy editing/updating with changes.

Thanks a bunch Brad! Great info as always 
Do you know if these things work fine in Mobu 2010? And do you think it’s worth sticking to 2010 for a bit? (I’m the only one in the team that’s moved on to 2011 currently)
The macro issue with relation constraints in 2011 seems to have been resolved in 2011 “advantage pack”
Yay!
