Performer 2.0 has the following flags for pfNodeIsectSegs [used to be
pfSegsIsectNode]:

PFTRAV_LAYER_NONE - don't intersect with any of the layers' children
PFTRAV_LAYER_BASE - intersect with only the base
PFTRAV_LAYER_DECAL - intersect with the decaled polygons

You can OR this in the mode of pfSegSet and get the desired results.

Hope that helps,
