Hello team,

I am trying the muscle setup workflow in houdini id. After 2 weeks, I still can not figure out how the apply symmetry works.

what I did below:

1. Loaded in alembic file.(muscle geos)
2. Unpack the abc file
3. Split the a-sysmetry parts.
4. Use muscle ID node. using muscle id.

It should generate the names for the mirror side. But it does not work at all. Can you show me an good example? Thanks

Best,

Hello, please share your hip file so I can take a closer look.

But in the meantime, ensure you are following the workflow as in the attached video capture.
-Go to the Symmetry tab on the MuscleID SOP
-enable the Apply Symmetry toggle
-enter your preferred naming prefixes for your Left/Right naming. (Something like L_ or Left_ etc.)

-Enter the viewport state for MuscleID,
-Click on a muscle to select it,
-Hit Enter to bring up the rename dialog
-Type the name of the muscle. Ensure the name you type is prefixed with your preferred Left/Right prefix.

If the name you type does not include the prefix, the string editing function won't find a substring to replace. So the ID will not be mirrored.
Also, the default mirror plane for this SOP is along the X Axis, with the origin at (0,0,0). Make sure your geometry is symmetrical about this mirror plane.
