In post #51 I did say The Scene.dat file was SHIII & that it doesn't have the Vortex problem only the SHIV version did, the modified one is an 8k version, I'm sure it is GWX but I believe the result would be the same (I will edit that version but it does take time & post results).

The main thing is to get a base version going first!
Still a long way & JCW is testing as well, but have climbed another rung on the ladder.
