Hi All,

I have noticed that a lot of my renders have these spots in the shadows, why would that be?

Using UberEnvironment and set Quality 4XHi

with and without some extra lights, I get that effect with my renders.

If you look at the image attached around the shoulders, some in the face. When I do a closer shot (face only) this is all over the render.
Any tips with this?

Using Daz 4.5

Hi Marchosius,

Presets are fine but I would recommend manually adjusting settings for a while, it will help you
gain a better understand of the UberEnvironment Lighting, which is such a useful tool for great lighting in DAZ Studio.

To answer your question:

You will need to play with two settings. ( I nearly always max mine out for final renders, it ups the render time but it is worth it )

Occlusion Samples the higher the better. ( Set mine to 128 for final render )

Shading Rate the lower the better. ( I drop mine to 1 )

Here is a link that might help.

Cheers Laticis

PS: Hair will max out render times under these settings, try using in conjunction with UberHair and turn off the RayTrace Feature.

Thanx for the link and info,

Just had a look in my settings and the Occlusion was set to 128 but the Shading Rate was at 8 changed that to 1, just to see what the render will be like, so just waiting for this to render out.

We are all chasing that wink

You will need to looking into the SubSurfacing Scattering properties of Studio for that type of look.

I’ve been chasing that for months.

Something I got close to…its not my best though.

The fact your still getting that issue means the is another player involved.

Can you supply a screen shot of your UberSet up please.

Looks good,

Now how about your Advanced render settings, what is your shading rate set at.

Screen Shots from my end.

Edit: Sorry about the posting size.

okay new test to try…

In the advanced render setting, increase the Shadow sample Rate to 64.

And lower the shading rate to .5
