Trying to get default Animation Modifier (SyncMarkerAnimModifier) to work for custom rigs

In Unreal Engine 5.0 in the Lyra project, I’m trying to use the SyncMarkerAnimModifier to create sync markers for animations on my custom rig.

It works fine on the original Lyra rigs, SKM_Manny and SKM_Quinn.
But on my rigs, no tags are created.

I’m not sure what could be wrong, like if there’s an undocumented step I’m missing.

The only difference I’m aware of is the foot bones in my rigs have different names. But that shouldn’t matter since I check the settings in the modifier match them.

Would appreciate any help!

SyncMarkerAnimModifier

Discovered that it actually does work by default, but only for animations that have root motion.
Didn’t think that would matter but it does here.
