Hi.

I am adapting the example from the Docs regarding building a full APEX rig in LOPs.

https://www.sidefx.com/docs/houdini22.0/character/kinefx/lopanimation.html [www.sidefx.com]

In the example there is just a tube. But as soon as I add two object it is throwing errors at me. Diving inside the APEX SOP_rig_builder I can see the deformation is working fine. But as soon as I come back out into LOPs and add a APEX animate LOP I can only deform one object.

I think this might have something to do with packing and unpacking but I am at a bit of a loss.
In the SOP_RigBuilder I have tried renaming the two pieces of geometry

/geo/ball.shp
/geo/tube.shp

to

/geo/*.shp

but it does not seem to like it.


Any help would be much apricated.

Regards. Mark
