Simulating Atmospheric refraction

Recommended Posts

Well I ended removing the extra sphere on the sun. Didn't need it at all and to get the sun more realistic it was a very easy solution.

I'm using the sky plugin to get the day and night sky color. I turn everything off like sun moon planets since they get refracted and lowered through the refraction layer.. The problem I'm having though is remnants of the sky tag are showing through like the glow of the sun that is lower than my actual sun. Also the nice color change effect from day to night gets messed up a bit coming through the refraction. I need the refraction so can't remove that but I'm wondering since I'm only using this sky and atmosphere effect from the physical sky tag, is there a way to make the sky do that without the physical sky tag or is that some internal feature only available in the tag?

you can turn off many things (even the physical sky , so you can make the sky color pure black ) or you can use compositing tag to get certain effects , maybe you can disable every thing except  the reflection and refraction .

What I would like to do is only use the color of the sky that is connected to the longitude latitude. It gives a nice representation of the area for the time of the year. What I would like to not see is the glow of the sun because my refraction layer in between causes it to be lower than it should. The sun in physical sky is easy to uncheck but the glow I can't find how to turn off. If that's not possible then is it possible to just create the sky color another way and then I can turn off physical sky completely. I'm using very little from it.

 

Also I want to track the azimut of the sun so I use the R.H of the camera that is targeting the sun. The problem is it's range is -90 to 270 and I need it 0-360. I tried using only range mapper because it seemed it would work but no matter how I set it, I can't seem to get it right. For example when the R.H of the camera says 0 and I move the sun forward, it goes to -1° then -2° and then when it gets to -90° to goes to 270. So the range seems to be -90 to 270 which I need to be 0-360

for the glow , it seems that you can't change it , and for the xpresso I don't use range mappers usually , I use compare nodes + condition nodes
