Greetings all;

I'm having a bit of an issue trying to render this scene. Everything comes out with either a graininess or fuzziness to the areas with bright light where it transitions to darker areas.

In this test render set on Superior (which is what I finally tried last- with the result you see here- after fiddling with every setting I coud think of) 

Camera settings are 50mm- Blur: 0%- Focus: 5ft - Exposure: 0

Figure was Skin Vued with pretty much default settings

Any tips would be most welcome.

 

Light settings for the image:

Which atmosphere did you load before importing the figure?  See if your sunlight has volumetric enabled.  Turn it off and see if there is a difference.  If there is, then we can see about using a better render setting than Superior (if Vue Studio allows that).  Because there may be other items to improve.

You have Optimize for outdoor rendering on in thne atmosphere editor, but is this an exterior scene? Looks like inside from the screengrab. Untick it to get a better lighting solution.

You have quite a lot of radiosity gain and skydomegain in the scene, and at the same time, the light intensity is toned down, which is a bit weird. Inverting this would reduce the noise.

To get rid of the noise, boost the atmosphere quality (try +1 on a problem area render, to check if +1 is enough without rendering the whole scene), and up the shadow smoothing.

Shawn and Bruno,

Thanks for responding! Really appreciate your time on this.

Bruno, you said:

Yes, it is an indoor scene, with light coming through a window...

And 

Shawn, you asked about volumetric light, which is what the main light is. I disabled that and here's another render, with Optimize for outdoor turned off, both sky gain and skydome set to zero.

There are no other lights other than the main light. I'm trying for a warm glow such as found in the early morning through an open window.

Not really much difference.

(Sun light (main light) settings: Pure white. softness set to 5, Shadows set 89%. If I set softness to zero, I get some harsh shadows.)

Rendering with atmosphere quality boosted up to 1 now.

Here's the full scene I'm working on (edited for content) Earlier render, was still working on textures on various items. This is when I first noticed the graininess. I was hoping a longer render would solve that, to no avail.

And here's a close up of the woman on the left. Still grainy, but not as bad.

Atmosphere quality bumped up to +1.0

How about shadow smoothing? In the atmo editor, light tab. But since the noise only happens on the figyres, my guess is it comes from the textures. Use some texture filtering in your renbder settings (33%) usually does the trick. To access texture filtering, you'll need to use your own render settings. If you don't know what to use as custom render settings, there is a Load button to load a Render settings file, simply load the Superior mode (for example), then you can access texture filtering by clicking on the Edit button next to Anti aliasing settings.

Looks much better to me.  Now the sandpaper skin is normal.  Just make sure your SkinVue bump setting was at 0.002 or less.

Bruno: It would appear the texture filtering is the culprit. Bumping it up to about 45% really reduced the noticable grain of the texture. I've used a number of different settings for various renders, but hadn't thought to open one of the default settings manually before

Shawn; Skin Vue for Vue 9 won't let you adjust bump (You can change the value, but it doesn't stick, changing back to the default value. My only complaint about the program, and I'm not alone as others have complained about not being able to change values) You can't change it manually in the material editor as Vue 9 Studio does not let you edit complicated materials, and will strip most of the material if you try. To do it, I would have to buy one of the Vue modules. I had a bit of a 'de-learning' curve going from Vue 6 Complete to Vue 9 Studio. What I took for granted in Vue 6 (i.e. object export, etc) , was no longer a feature in Vue 9 Studio.

Thank you Shawn and Bruno for the help on this one! 

Much appreciated!
