Look it's the sun!!

Sketchup really has one. :lol:

I guess I never thought there was actually a point/dot/thing.

first is without Aperture Diff, second is with.

Hi Cro!
..interesting!
I always wanted to test aperture diffraction, but when I enable it I always get fireflies or shiny dots :?
How did you do it?

I messed up first is without aperture diffraction
second is with. pic names are correct.

anyways, I was wondering if I could get a nice evening/warm/dusk type sun from just sketchup. Because, in skp it just gets darker.

In other renders created in Blender or whatever, I think you can set parameters for the sun and I've seen the sun in them, so I was jsut wondering if this was possible with skp.

I just aimed the camera due West, North is Green axis and hit render and adjusted until I saw the sun. Weird that it has that black ring around it, but it is kind of a nice sky.

Not sure about the fireflies and all, there are no materials in my scene except the default skp mat. I just rendered for awhile and saved the pic without apdiff on and than turned it on and that's it above.

I think a nice sunset is next.

Reminds me.. It would be neat to be able to control the brightness of the sun.. Maybe by changing the time of day or something..

The black ringing maybe Pibuz can explain a bit now :)

As far as I know camera diffraction works with f-stop, smaller apertures (higher fstop) tend to generate a wider halo, and also more vignetting. If the f-stop value is not too strong then camera diffaction computes faster... well, it's spread will be tighter.

I hope I reminded well !

afaik the halo could be a result of the MN Splat filter... a quick gausian test could proof if I'm wrong :)

Vidy: a smaller aperture radius while using diffraction. It's noted above :)

Yeah, this was what I was trying to get at. What if you could control the time of day?

Please PLEASE learn something before you post!! Obviously you don't even know the absolute basics of Sketchup.

Hehe, whoops sorry. It was hidden in the shadows menu. Hehe. I just wasn't aware than skindigo tapped into SUs settings this much. :D

If you're talking about the black outline: That's a VERY old one!
I did those multiple times. If the posts aren't lost in one of the site-shutdowns, you'll see such pics by me too ;)
(also some with extreme turbidity-values (20), resulting in a green (O.o) sky, which though isn't a bug-. as realistic values are in the range between 2 and 6 or something)
