Aliasing setting in interior scenes .... HELP

[mzmeskal]

On the image below you can see a "dressing wall". Take a look at the edges of the door, it looks just nasty, but I don understand why.
I set adaptive subdivision to -1,2 and use catmull rom as a filter.
I also get these weird artifacts above the door and the lighter spot below the wardrobe....??? any suggests?

BWT do you know what causes those white blotches on the left side, inside the wardrobe?


If you want to give it a go....

Make the whole scene modeled properly, means that everything should have thickness.

If you have antialiasing problem then increase the settings to 0/2 or even higher.1/2; 1/3

re

vray or standard materials?

I think part of the problem is that there is no light source other than skylight and thats only coming from one end. I've found that if you use only skylight it's very difficult to get rid of all the artifacts without very high settings. Add a vray light with vray shadows and it should produce a cleaner render.

I also agree with losbellos, give the walls some thickness to prevent the light bleeding. What setting do you have for the irradeance map? For interiors I always use -3,-1 or for smaller details or trouble spots I use -3,0.

Another thing I noticed when I looked at your scene. You are using blurred reflections on several materials without using interpolation. If you set them for interpolation and set the reflect interpolation to -4,-1 your render time will drop dramatically but the quality of the blurred reflections will still be good. Setting the glossiness to .85 or .9 is usually enough for wood floors and this will also help your render time. The lower you set this the longer it takes to render. Hope this helps!

Thank you very much guys......one never stops learning, thats why I am asking all the time. Everyone on this forum has a part of a common knowledge....

...just makes me wonder if all of us joined to make a guidebook for vray it would have been a bestseller....

Thanks again

the light that bleeds thru in the interior of the walls in the closet can be eliminated if you check 'sample visiblility' in adv irradiance map settings.

also, I think that big white spot under the closet, provided you and i mean the same thing, is just a basic reflection of the white in the back of the closet. not an error.
