Hey,
yes, I'll send the scene now via wetransfer. Here are the test renders. One is the old method where I manually added each house, the other (with grass protruding) is the FPset. Houses (vrayscenes) each have a large box the size of the pool and the size of the house + driveway in them and it's clicked unrenderable. Boxes are 200 in height and located in -100 so should be ok.
