V-Ray 3.4 aliasing

[romansimon]

Hi. I am using V-Ray 3.4 with 3ds Max 2014. No matter what I change in the settings I get aliasing. I read so many pages and posts on the Internet, but I can not apply anything. I just get the same result. Please someone advise anything.

What kind of help do you expect if you give no info on what kind of settings do you use? Based on a picture..idk, if that edge is not chamfered i'd try that, ot maybe make that white material a little more gray'ish..or reduce intensity of the light

Antialising is only one control on VRay, goes from 0 to 9999, will you ever use that value? NO! most of the time 1-100 will do just fine.

This also will vary depending how large is your image, over 3k you get nice antialising.

Most of the time is not recommended to use sharpening filter such Mitchell but if your image is small and you are getting moire effect, in that case it may help.

 

Things to know also are, VRay and any raytracer will have hard time antialising on areas of height contrast, in your case, your white material is very white and the windows is a lot darker, so that edge will need more samples to clean up.

One way to help VRay is not using extreme color such 255 whites, or 0 black. Also you could tone map your render with Reinhardt for instance and use a burn value of 0.4, this will reduce the color variance between whites and black, making the antialising works better.

render larger than you need and downsample afterward or paint it out. much faster than nit-picking the mathematical flaws. I'd be more concerned with the choppy geometry on the forward structure
