Invaluable, but oh so prone to breaking your hours of work. It's a clear 5 star addition to VAM otherwise.
So here's a bunch of pitfalls I've found to avoid if you don't want to lose hours of work.
?
Don't turn the atom off and save the scene.
Don't switch the CUA asset even by accident.
Don't reuse the same atom if the connection has broken once.
Don't use the name of a past CUA atom that had it's effector connection broken.
Don't use backslashes "\" in the CUA atom name. Possibly other symbols will break it too. Dash - and hashtag # are fine though.
Don't rename the spawned effectors ("X_X_XXXXX_CCD_Effector" etc.)
?
You won't be punished for doing any of these things till you reload your scene. Then you'll find all triangle atoms (effectors) have turned to squares, and then you gotta clean up and redo the setup, while you mourn the loss of animation work.
