That sounds like we are heading in the right direction. Thanks!
Let me be somehow picky: You are talking about having the houses in the same geometry, that's already fine. The next thing to care for is that they are also in a minimum amount of osg::PrimitiveSet instances. That's about minimizing the amount of draw calls that happen underneath. The best thing would be to have one single *DrawElements instance doing the whole geometry in a single draw call.
