Hi, thanks again for your help. I am still recovering but it was delivered

tech support for the win...and just like that IT WORKS, changed the expression priority of the parent constraint from 0 to 10
and the eyes stay where they belong

VOODOO

yeah, your movie looks great! wish i could do that ; )

hi, was too much in a crunch for deadline, will have a look, thanks

i am going to open a ticket with tech support. if you'd like to have a look at my file that's bugging out the eyes, here is a reduced version with no textures. see frame 111.

ok thanks very much for trying

what i want to do? i'm just moving the head, I want the eyes to follow. somehow the eyes are a frame behind here and there. I was using XRefs to the model but it doesn't seem to like that. Where i just merged a copy of the model into the file (no reference) it seems to mostly work, but not 100%.

my joints are aim-constrained to their targets, which are un-constrained children of a main eye controller, which is an unconstrained child of a null called Eye Rig, which is then constrained to HeadCon+. It seems like the joints should be more directly constrained to the Head but i can't figure out what that requires.

it might have been some XRef connection, I finalized the rigging on the character and brought it directly into a scene, seems to be working fine. MOVING ON...

maybe the XRef is breaking, I guess i will just try to go with the rig as is, and import it directly, not XRef...argggh. already did some animation

i opened the EyeRig.c4d file, and it seems to respond to animation ok.

well that's absolutely maddening.
