It would be good if there was an option to choose MAT IDs together with REFERENCE geometry in FP.
1. RC generated model with various geometry but also with `Reference Triangle/dummy` included witch have specific MAT ID.
2. FP distribution mode set to REFERENCE + MAT ID to match RC reference (could be multiple numbers for filter)
e.g. RC generated car parking lines with TRIANGLES as Reference for FP to distribute cars between lines. (RC also can do the job for randomly rotating and shifting cars/empty places etc.)
I already use this approach to distribute cars and it works great. RC do the job for rotating/shifting etc. and even adding handicapped section via different spline ID.
Only issue is that I need to create two RC object, one for parking lines and other just for reference.
With Option for `filter` by MAT ID in FP Reference mode we could use complex geometry as a Reference.
Hope it make any sense...
