Edges when I do renderings in vray

[nodar1978]

I guys

I'm new in vray and I've got one problem, edges and noisy, please have a look on attachment (red circles) and give me advice how tp do this rendering better?

thank

The highlights along your glass could be because the vraylights "Affect Specular and Affect Reflection" isn't unticked. The black lines are probably a result of your AA filter. Which filter are you using? The noise could be a result of quite a few settings. Post your settings so we can check them out and help you out.

thank you very much, i'll make the rendering and i'll send new visuals, and settings as well, thanks again

hello here are my settings for vray renderer (plane lightings), for lightings i use 3 vray lightings, 2 behind the shelves, and one on a ceiling,

Hmm. I think there are some basics that you should really rethink before continuing:

 

Image Sampler/AntiAliasing

Image Sampler = Adaptive DMC

Antialiasing Filter = Mitchell-Netravali

Anti-Aliasing is, like most things, a matter of personal preference, but Mitchell-Netravali is a good place to start.

 

Indirect Illumination

I'd go with Light Cache on your secondary bounce instead of Quasi-Monte Carlo. You can play with the levels of the Irradiance Map and Light Cache, but leave them both at 1.0 for now.

 

Irradiance Map

HSph. subs = 70

Inter. Samples = 60

Sample Lookup = Density Based

 

Your settings are too low for any kind of decent results.

 

Light Cache

Subs = 1000

Sample size = .02

Scale = screen

Inter samples = 10

 

Number of passes = your number of cores.

These are good, solid Light Cache settings that are not too high, and not too low. They will get you good results at relatively fast rendertimes.

 

GI Environment

Dude, turn on that Skylight override! Leave it as a multiplier of 1. Play around with that setting.

 

Give these a go and let us know how you're doing.

AA. Leave Catmull and Mitchell and try VRayLanczos or Soften or even Area.

[Christopher Nichols]

What is actually happening is that you are using a sharpening filter on your AA, probably something like catmull rom. When you have bright color (like your light) next to a not so bright color, you the AA tries to sharpen that edge and because the difference in color is so strong, it ends up creating negative pixels.

 

You have several choices... use a different AA filter (which is the best solution), or clamp your colors.

Here's a nice guide that walks through some anti-alias stuff. Example 8 is great:

Dear friends, I have done your advices, and still can’t get result as it should be, I think I made some mistakes, please if you have a time, just open my project file and do for me quick settings for light and renderer please. this is closed area, without windows, so here are 3 lightings only, 2 luminance lighting backside of shelves (white ones) and one lighting on a ceiling. I also attached picture (real photo) how it should be look like, if you see my first attachments they don't look like they should. waiting for your replies. and thank you in advance

Another reason you could be getting that outline around your bright areas could be the combination of your light intensity with your exposure settings.

 

If your exposure is very low, but your light intensity is very high, v-ray will create that edge effect that you are getting. But if you increase your exposure (not sure if you're using v-ray camera), and lower your light intensity it might fix this problem.

 

Good rule of thumb:If your light has an intensity of 1.0, you should not be getting any edge effect even with some of the edge enhancing AA filters.
