Hi Reece!
Have been "figting the sun" here too and rather pleased so far...
...but when clear sky and sun is up high I get like a green halo around it? Is that related to the SHIV scene? Do you have it?
Otherwise like the scene-work very much.
There are settings in scene.dat regarding sun-size at different angles on the sky, but haven't had the time yet to test it out...
