trace_set is not working with xgen

[Anonymous]

I setup a example scene include the meshes, paint effect (nHair) and xgen (Interactive Groom), and I create a aiTraceSet with label name is "exclude_set", both sphere mesh and paint effect and xgen set the trace set to "exclude_set", but xgen with trace set setting is not working.

Is xgen not support trace set or it is just a bug?

Is there any solution which behavior like trace_set for XGen

This my trace_set settings

This plane shading network with aiTraceSet1

The poly mesh and paint effect look are good, but XGen (Interactive Groom) is not working.

Here is my example scene
