Room corners glowing

[Macker]

your DMC sampler settings are sooooo high too.

I usually only add sun for day scenes without sky portals on windows. It seams that made BF/BF render black. Now I added lights on all windows and BF/BF is ok, but rather darker than LC so I think overlaying those two makes those glowing edges. Any reason LC is so much brighter? I guess I can reduce secondary multiplier to 0.7

LC generates lighter result because it could trace much more samples than any other GI engine. More rays bouncing in the scene will definitely make the scene a bit brighter especially for enclosed scenes.
If you still have troubles with solving this case you could send the scene or simplified version of it for investigation.

I never use diffuse higher than 195...walls are much darker than that. Will try to reset.
SR has a specific way of setting things up...it usually works...usually

That should be ok but those table mats don't look like <195...

[Crayox13]

I think you mean the bottom plate. No, it has diffuse 165, same as it's fresnel reflection and no texture. I think it's just more effected by the glow...light bouncing

So i tried to change my render do default and than back vray which reset vray, than I manually set BF/LC but it was the same. Then I went to SR, hit button "vray reset" which reset something else because now LC is much darker than before - with all the same settings, and it seams better, still some glow but now that rendered corner is black while there is still some glow to the right.

I'll try removing objects next.

Have you tried with a simple diffuse override material with glass excluded? Maybe upload your file without interior objects (only walls and glass), so people here could take a look?

[Crayox13]

Yep, it's gone now. So I should search for troubling materials. Though after deleting most misc objects it still remained.

So I should search for troubling materials.

This might help with the hunt for materials that aren't compatible with V-Ray...

(
	local allSceneMats
	
	fn matSortFN mat1 mat2 =
	(
		case of
		(
			(mat1.name < mat2.name):-1
			(mat1.name > mat2.name):1
			default:0
		)
	)
	
	fn getSceneMats =
	(
		local sceneMats = #()
		for c in material.classes where c.creatable == true do
		(
			mats = getClassInstances c
			join sceneMats mats
		)
		qsort sceneMats matSortFN
		sceneMats
	)
	
	fn analyseScene =
	(
		clearListener()
		allSceneMats = getSceneMats()
		for om in allSceneMats where (not (areMtlAndRendererCompatible om renderer:(vray())) or (isKindOf om architectural)) do format "% - % %\n" (classOf om) om.name (refs.dependentNodes om)
	)
	analyseScene()
)

It will list all non-V-Ray materials in the listener and tell you which objects they are on.

[Crayox13]

I already used vray convert just in case. But to test the script I created a standard material and applied it to a box. After I ran this script nothing was listed in listener. Maybe because I'm on MAX 2009.

[DanielBrew]

The script is really looking for Architectural and Raytrace materials etc. so if nothing is listed then there aren't any of those in your scene. Standard materials are in theory at least, compatible with V-Ray so I don't check for those.

I work with a lot of geometry imported from other Autodesk products so I have tools to clean out the stuff V-Ray doesn't like.

If you still have issues, just email me the scene and I'll let you know what's wrong...

Chaos guys solved the problem. I had to check retrace option in LC. Value of about 5 started to fix it and removed those white areas in corners.
Thanks!
