Hello,
maybe someone can shed some light on what numbers the vd->lhit function reads out within Output(PluginShader* sh, ChannelData* cd) routine.
I thought that this gives back the vertex id of the rendered polygon, but it doesn't. The lhit value gives slightly higher numbers or even negative values back when the second CPU starts to kick in rendering the same polygon.
Isn't there a way to get the real polygon id back from within a channel shaders Output routine?

Just to add this:
I already tried to use TraceGeometry, but it gives the same wrong result for the poly id even when using vd->lhit=0 in advance.

I am sorry,
I missed the ID_to_Obj command which also gives the local polygon id.
