Hi zombie, let me see if I can explain why I said what I did and why I think it's not a static effect .
First question, have you ever actually looked at the sun ? Like on a cloudless day, the sort of action your doctor will tell you would blind you ?
Well it does actually look more like the first image than any of the others and thats what I'm talking about...
The problem is you can look at the plane the scenery and the sun is wrong because of that glare.... and here I agree with you.
If I was to write a specification for the sun as wanted by a user it'd be something like..
The sun's glare flare intensity to be variable depending upon the sun's position relative to the screens centre and the length of time..
Such that a glance of the sun past the screens centre produces a short intensity flare which returns to nothing quickly..
A long lingering look with the sun 10 degress to the side of the screens centre results in the flare expanding and a residual after glow remaining when looking elsewhere which disminished inversely proportional to the flare intensity..
The aim here is to be able to hide behind the sun as a fighter pilot.... and you could only do that with the first image....
