vraysun+vraysky+vraycamera for dummies

[nvanherpt]

finally got a bit of time to look into this, better late than never.

where can i get a run-down without searching through 50 million posts for tidbits of info? is there a proper tutorial around?

[Da_elf]

the help manual would be my 1st choice

[DaForce]

Well this aint no tut, but some helpfull info.

Leave sun and sky at the default multiplyers 1.0 and then use the camera the control the light levels.
It works quite well with LWF as well

niko, there are some very usual bits of information in the help file (it even has pictures )

Sun/Sky

The sun/sky is great! I have a question. When I get my vray camera correct and my image looks good the sky is to dark and when I drop my sky into a slot it is white. How do I have control over this?

here's a cam/sky tut: http://www.vrayelite.com/camsky.php

vraycam/sky

I am using everything you pointed out in the tutorial, except I leave the sun and 1 and adjust the camera. I didn't know about the photon emit radius being the size of the scene so thanks for the tip.. Even in your animation the sky is dark until the sun is behind the scene.

[DaForce]

You dont need to worry about the photon emit radios at all.. UNLESS your using Photons (they dont really get used anymore) or/and Vray:Caustics and that is the light that is casting the caustics.

Appart from that you can basically ignore it.

@glorybound: You can detach the sky from the sun and adjust it independently if it is too dark. Also you could try mapping it inside a Vray dome light.

i'll remove the mention of changing the photon emit radius on the tut. i dont recall why i thought it was important (seemed like it was at the time) but as daforce said it really isn't.
regarding the sun's multipler being so low, i remember someones post awhile ago using similar settings and i stuck with those settings for all my tests. using the test scene on my site, if i have the sun multiplier at 1.0 i need to bump the f-number up to 24 to get decent results. the sky is definately brighter during the day but in the evening i'm getting unwanted results. as always its just a matters of tweaking the settings to get whats best fot you.

joe, dont adjust your f number to reduce brightness increase the shutter spped, this is what you would do in a real camera

[nvanherpt]

cool thanks guys, i've snuck in a couple of days off at the mo (i can't beleive my luck) so i'll be looking at this on monday.

cheers
