I found a pretty dumb solution for matching from IK to FK. I created some dummy controls that track the correct position for FK controls by getting the transform of the deformed skeleton. Then when I need to transition from IK to FK in Apex scene animate, I copy the transform of the dummy controls back to the corresponding actual FK controls. Then I change the mode from IK to FK and I can keep animating in FK.
The same should work for matching from FK to IK.
Is there a way to automate this process?

danfitz82May I ask how you load the custom code into APEX Scene Animate? Thanks.
the custom code is loaded by the APEX Scene Animate node to act as a sort of sub-tool.

In Maya, you can do FK/IK matching with Python by getting the current transformations of the controls and doing some calculations. Is there a way to use Python to manipulate controls in Apex when animating(apex scene animate)? At which step should FK/IK matching be implemented (where should the scripts live and how do the user activate the script)?

I want to animate in view 2, and I want a view which is in sync with view 2 but only display geometry(no control guides). View 1 syncs quite well but I can't hide guides. I can hide guides in view 3 but view 3 does not sync well, meaning the cube does not rotate while I rotate in view 2, but only rotates after I stop rotating in view 2.

Did anyone manage to solve this? Rocky9.5 + Houdini 20.5.487, still 0kb and the same error message. Everything works if the gallery location is set to a local disk instead of my NAS. But everything else (rendering, caching, etc.) works on the NAS.

I am also looking for this: IK robot leg with 5 joints, each of which can only move along one axis. Perhaps we need to reach out to actual robotic engineers.

tamtejohnlilpyAttribute string edit works directly on boneCapture attribute, no need to unpack
I figured out how to get rid of mixaomorig: in boneCapture. use capture attribute unpack, then attribute string edit, tick Detail, choose boneCapture_pCaptPath, for editor, tick use regular expressions, From mixamorig:, to, just leave it blank, and then add capture attribute pack in the end.

Ahhh thanks. boneCapture*

As for the skeleton, same as above posts: attribute string edit, name, use regular expressions, mixamorig:, blank.

Attribute String Edit does not actually get rid of mixamorig: from the first output(geo) if you select boneCapture. As a result, the skeleton does not move the geo, you can test with just rig pose and jointdeform. I am stuck here also.

For those who have used Karma cpu extensively, how is Karma cpu compared to other cpu renderers in terms of capabilities, speed, and stability?
