Nice work. I'm not entirely sure about the colours, but that might be a local issue: ftp://abbeytheatre2.org.uk:2121/flightgear/Tempest/Tempest-skydome-shader.pn g > The non-shader version should look just like it used to, but on some > occasions I think the sunset effect is a bit misplaced.

I can push the shader and effects file into git - but someone else will have to pick up the flightgear and simgear patches Vivian ------------------------------------------------------------------------------ Forrester Wave Report - Recovery time is now measured in hours and minutes not days.
