Well, it looks like I'll have to rebuild. I lost all sense of proportion while building on OpenSim I'm afraid. I just looked around on the main grid and have come to the conclusion that 4.5m is the best minimum.
I can't just enlarge my existing build because it's in multiple linked sections and there are too many 10m prims. I don't want to touch mega prims either because transferring between OpenSim and the main grid will become a nightmare.
Ah well. Back to the drawing board. I was just about to start texturing too (my favourite bit).
