I've not had time to explore CShop fully, but I'm sure that I had 6 children on a 6 block room. Maybe five were pivots or null entities and all the room data was in one entity, but it seemed a bit of a coincidence that it just happened to be 6. I'll give it a quick test with something bigger and see what I get.
EDIT: I made a very quick test. 15 blocks with identical texture properties. The b3d loads 25 entities. That's a lot. As I said earlier, I intend using CShop to create very complex but small scenes and I'm going to end up with a couple of hundred surfaces before I add anything but the architecture at this rate. I can write my own loader which combines as it loads, I suppose, but otherwise it's going to cause serious problems on GF2-class cards.
