IIRC the sprites are distributed on the surface of a squashed sphere, which might explain why with small numbers of sprites more than 50% might disappear.

I'll add it to my TODO list :) Presumably making cirrus clouds after more sprites doesn't make for very realistic clouds because of the size of the cloud structures? -Stuart ------------------------------------------------------------------------------ Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.
