Skydome?

[kwistenbiebel1]

Hi all,

Is there an option to render with a skydome?
I ask this because i have difficulties to control the intensity of direct sun light.
I still don't know how to render an overcast day with physical sky.

thanks.

BTW: it's so quiet lately on the forum...

Re: Skydome?

There is no sky-dome at this time. I believe V-Ray for Max has a dome that can be used. There are no clouds in the V-Ray sky system - but I believe you should be able to create a haze effect by manipulating the turbidity / ozone parameters.

Perhaps if you can't make the V-Ray Sky look exactly as you wish you could use an hdr image of an overcast sky?

I tried a HDRI of a clouded day...but the sun shines the same (as bright).
Can it be that using HDRI doesn't override the sketchup sky?

Thanks

Re: Skydome?

If you are not using the Sun/Sky texture but still have "Default Lights" enabled then you should get a Direct Light with the Sun's position. So you could have a direct light for the Sun - in addition to your hdr environment for GI/BG. Also - in another post I explained the sun/sky params. I'll edit my post and put the link to that topic here.

Ok Joe,

That explained it.
Thank you very much...it would have taken me ages to figure that out myself.

No problem - I'll make sure we get an environment tutorial going if we don't have one already.
