One thing that’s always been a quite controversial topic in SL is the creation and usage of megaprims. SL itself imposes a limitation on the physical size of any prim, which is 10x10x10 m at maximum.
Due to programming gaps and errors though there’ve been people around in the past, which created found ways to overcome that limitation and created bigger prims than that. Since you are unable to create those prims by normal means, those have been sold or just been given away in big packages for free and still are. In the times of Havok I being the physics engine running all over the grid one of the main argument against the usage of megaprims was that it creates unnecessary lags.
