i have in 1.70a using the sun position script made a scene using a sphere as the sun
my issues is is that the sphere just looks like a white circle in the sky and hardly sun like (Unless you are missing your atmosphere)
i am using cycles render and i have the sphere emitting light by making a material using surface emission (make a material and select emission in the surface bit under the surface sub menu thing) with strength set to 700 and the colour to a yellow (that changes the emission colour)
i would attach the file but for some reason the upload thing does not work and apparently i cannot put links in (unless i can then i will happily supply a dropbox link so someone can have a look at what i’m attempting to do and give me pointers as to how i can do what i am trying to do)
