      Hi schnoidl, save early, save often. Before making it editable and safe incrementally.

      Weighting can be done at different times in different ways. The Character bind process weighting will not be available at that point. To leave the Character in its complex state is not an advantage. But explore it and see how much more organized and usable the rig is afterward.

      I try to keep the question around one theme per thread.

      The XRef data was not included and seemed to be a different idea. What do you like to achieve with XRef? Perhaps we handle it in a new thread?

      The HUD (Controller) is just splines; double click. Typically, the workflow is to click on the Splines in the Editor view. The idea is that the rigging optimizes anything for the animated artist, which means keeping the eyes as long as possible on the editor screen, not in the attribute manager or on long lists of objects. As a character animator, you want to focus on the creation of expression.

      Cheers

        ok, thank you. I am still tweaking the weighting, so will hold off making editable. my Eyes are still lagging, what is the proper way to constrain them? that can be my single topic ; )

              my animation is taking place in a file with an XRef. I made that editable, then made the Character Object editable. Still the eyes are lagging. The joints are aim constrainted to the L/R targets, which are parented to a main target, which is a child of an overall null called EyeRig, which is parent constrained to Head Controller, or Head Joint, neither of which works. should the joints be more directly constrained to the Head Joint somehow? I just tried adding a second constraint tag to them, parenting to head joint...still lagging. sorry, i don't get it.

                could it be some kind of expression priority?

                  Hi schnoidl,

                  Please share more data; I can think of many combinations of XRef and characters being animated.

                  Here, I placed the character into a scene via XRef and moved the character, all fine.
                  https://stcineversityprod02.blob.core.windows.net/$web/Cineversity_Forum_Support/2024_Clips_DRS/20240917_XREF_Eye_no_delay.mp4

                  I later animated the head and eyes, and there were no problems in the XRef.

                  What exactly do you like to achieve? Please share details, as I can't see your results. But also, seeing "eyes out of head" images do not tell me much, I take your word for it, it is the same data. Describe what you do and where. Thank you.

                  Cheers

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

                        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

                          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...

                            Thanks for the updates, schnoidl.

                            I had hoped for more workable details to understand what you want to do, but the last four posts have not included this information.

                            Good luck!

                              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.

                                Hi schnoidl,

                                Here is the file, then a project with an XRef that uses that file and a screenshot showing how I can see it. You need to place the textures into the tex folder before opening it.
                                https://stcineversityprod02.blob.core.windows.net/$web/Cineversity_Forum_Support/2024_PROJECTS_DRS/20240918_CV4_2025_drs_24_CAed_01.zip

                                You had two sets of eyes in it, but you never mentioned it or explained why you added those. I used one pair only.

                                If that is not working, please check with tech support:
                                https://www.maxon.net/en/support-center

                                I can't reproduce the problem.

                                My best wishes

                                    You're welcome, no feedback or anything if the files work on your side. No worries I hope you have more progress with tech support.

                                      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.

                                          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
