Vray noob - usual dark shadows issue.

[stayinwonderland]

(see attached).

 

I've been following the V-Ray Advanced Webinar from 3dats.

 

I've tried everything but a) my shadows are too dark (do you agree?) and b) the ground is really bleached and burned out.

 

What I have: Physical camera, Vray Sun, irradiance map and light cache.

 

What I've already tried: Tweaking many differing color mapping settings. The values don't seem to change anything much at all, even when I put in quite drastic numbers.

 

I'm very new to Vray (just started today) so if you could go easy on me with the ol' prior knowledge

Color mapping won't help with your shadows, you need to tweak the vray sun settings.

Here is a link that explains the different settings. http://www.spot3d.com/vray/help/200R1/examples_vraysun_sky.htm

I usually stick with Reinhard and a burn value of .5 or so.

That's a good overview of the sun. So cheers for that. But it doesn't really talk about shadow levels. The best compromise I came up with was increasing the 1st light bounce to 1.6 to get more light moving around, then I manually tweaked the RGB output of the grass to tone it down. Does this make sense?

[AubreyM]

No not really. I almost never take the bounces over 1.0 but that is just me. I think you will need to play with the Vraysun settings in combination with the camera settings to get the effect you are looking for. I can't give you settings because each scene is different. The big ones for the sun are z height, size and intensity.

Good luck

Ok then, i'll see what I can do. Thanks for the tip

Check the pictorial by tush bobo in the following link:

Does it give you an idea about your dark shadows?
