Avoiding Graniness

[Mauricio_di]

Hey Guys,
I've been trying to fix the settings of my render, specifically avoiding graininess, I have tried everything written in manuals and forums like:

1. Secondary Ray bias 0.0001
2. Adaptive DMC Max Subdivisions= 50
3. DMC sampler Adaptive ammount= 0.85
4. Lights subdivisions = 32 regularly is 8 I read that to enhance interpolation and avoid graininess you can soar it to 32.

And since I'm using IM and Light Cache I shouldn't be worried about DMC because is not set as primary engine. The settings that I'm using are quite good 1200 for lightcache and for IM Hsph. SubDiv= 100 and samples=40


Please if anybody knows hot to improve it something that I haven't tested reply me Please!!!:P. I'm getting tired of roaming around on the same issue.

Re: Avoiding Graniness

Very important are the noise levels of the image sampler and DMC sampler (you can use the same value at both). I use:

* daily final rendering 0.015
* preview 0.03 .. 0.02
* low noise 0.01
* extrem low noise 0.005

Are you sure you use IM+LC? The IM is a good help against noise. Also it helps to enable "store with irradiance map" at the rectangular light properties.

Hi Micha,

Thanks for the replay I enhanced the noise to 0.005 and it worked! . I also enable store IM in the light properties.
I was using 0.015 as you suggested and I was very concerned about using 0.005because fo the rendering time but it took almost the same. Now I think I should improve the reflections on the glass textures it looks funky, maybe is because of the illumination and the HDRI used for background and GI. I don't know what do you think?

Best Regards,

Mauricio

Re: Avoiding Graniness

Try to round any edge or use use the Rhino smoothedge tool and use the extracted meshes for rendering. Round edges are very important for a realistic look.

Did you test the starterkit from the forum "tutorial ..." section?
