Assign Trace Set property (ar_trace_set) to Packed Alembic Primitive

Houdini 19.0.531

HtoA 6.0.2.1

Arnold 7.0.0.2

 

Hello, I am trying to set an "ar_trace_sets" attribute on some of my packed alembic primitives so that only some of them are in the different set, however no matter how I set the attribute on the primitives the property doesn't come through to the renderer. 

 

I expected it would work the same way as setting "ar_subdiv_iterations" or "ar_subdiv_type". 

 

In kick info trace_sets is a STRING[] type, am I maybe setting the attribute on my primitives wrong?

 

I have tried the following:

s@ar_trace_sets = "myTraceSet"

s[]@ar_trace_sets = array("myTraceSet")

 

I can only seem to set the property using Arnold operators (set parameter).

 

Any help appreciated, thanks, 

 

Adam

Sorry, but we don't support array parameters with the alembic packed primitive overrides.
