With eyepos, it should be possible to do the vector geometry to get godrays working from any camera position, so you don't have to be facing the sun to see the effects. It's up to vtastek to implement that if he wants to though.
I want to but it is not that easy, that would need drawing my own sun off-screen and apply directional blur in this off-screen area. These are real challenges for a shader newbie. I am on it though. (I can use documentation on off-screen rendering. I'm intimidated by it, but maybe it turns out an easy thing. I need somebody to point me in easiness of this thing. )
PS. And I am working on v3 of timelygodrays, trying something to perfect transition phases, what I have in mind is using the incremental 59 minutes within an hour to my advantage. I think I would need using lerp and/or clamp functions to make it continuous from noon exposure to golden hours exposure. After that I can focus on off-screen rendering for v4.
PPS. I will convert some of my MGE shaders to OGE as well. Wait 4-5 shaders from me.
