I've been very keen on trying it as I'm now very dependent upon BSP2-compatible engines for my mod. RMQ is a great engine but has some RMQ-mod specific stuff that didn't entirely fit with mine, so naturally equake.bsp was the first map I tried with this engine.
I've got to say, MH, it's just perfect for my mod. The effects are more tuned down, subtler ones - the glow from the lightning for instance lights up walls it immediately passes, rather than everything within 20ft of it. It's also smooth as silk; marvellous frame rate on what is a large, complicated, non-optimised, mess of a map. The light level is also just perfect for my "overly-dark" mod

It's really motivating to be able to access such innovative and enabling tools and programming - so, thanks!
*Apologies if this should have been in the Engine Programming forum; have only thought that as I finish, and I'm too lazy to copy it all over...
