Hi guys,
What is the prob here..
Low on subdivs of my vraylight ?
It was set to 8.. .standard .. Guess so since the wall not cathching direct vraylight don’t have it..
Also.. it’s rendered out at 640x480 and took 31minutes on my 2.8 dual xeon. Not fast with the results I got..
Any ideas ?
Screen shot of the settings may help .. 
Well I think it’s my vraylight.
Turned everything in plain white.
Rendering took 10minutes..
My vraylight was set at 20.. maybe a little to much ?
Vraylight ticks: ON, IGNORE LN, STORE WITH IM, SMOOTH SS
how the placement of the vraylight? sometimes that noise can happen if its intersecting geometry. I remember someone else having a somewhat similiar problem.
It’s set to visible so I have a whit washout outside..
That’s why I make it so large outside..
Suggestions
do you have self illuminated objets ?
You can put your Vray light only the size on the window

I would try making the light about the same size as the window opening, right now there is a lot of bouncing happening between the light and the wall.
I did a rerender putting my vraylight like you said.
and got 4:40 rendertime in white..
Black spots appear so I will do a rerender with interpolation samples in IR set to 40..
with those real black spots that could be caused by intersecting geometry, try changing the " secondary rays bias" under global switches to around 0.01 or 0.001

Mabee a little off here :roll: … sorry in advance
I got that kind of result whenever my min rate and max rate are too far appart on a final rendering.
you are set at -5, 0,
If you want to keep it max 0, start no further away than -2…
I don’t know if that is a rule of anykind, but I noticed I got better result when I have no more than 4 passes..

Okidoki.. thablanch
Is this last one true ?
Anybody who can say why also ?
Very interesting…
Thx m8

Trying it out now.
this wouldnt be causing the blotches I think but do you need to use smooth surface shadows? i’d turn that off
also, turn off generate caustics for the light (maybee also not relevant)
I get blotches when there isnt enough light in the scene…tried adding a vray light sphere in the middle of the room?..this is kind of faking it tho 
lastly, the most obvious…are all of your materials vray and do you get any overbright messages?
Paulison,
Smooth surface shadow and generate caustics (don’t have them on in my vray render settings) is this a huge chunk of the total rendertime do you think? Don’t have time to rerender now but would be a great tip though.. how much % ?
Blotches is indeed a lack of light or subdivs.. in my case subdivs..
The materials I also know and are all new vray materials.
Thx !! 
Did my final renderings at 2400x1800 and resized them here..
i have this strange black line from sink to sink.. couldn’t think of what it would be.. ?
Hi, nice renders.
Seems just a normal problem. Check normals on those faces.
Marco
Looking better … the dark line is probably due to Boolean ! .. if you must use Boolean then make sure the object has enough subdivs to cope with it.
Thx guys,
Well It’s an imported solid (acad 2k5) in which I did a boolean operation of 2 extruded polylines. Would it be better to boolean the regions first and extrude then ?
Natty you mean the material subdivs ? Or object → surface properties → subdivision presets HIGH ? Don’t know if this is correct ?
Nicolaas
I mean surface subdivs …
Have a look @ this file .. its 2 ellipses in a rectangle … select the rectangle then add the ellipses to it through Edit spline …then extrude.. so much cleaner and not thousands of lines all over the place.

Thx natty.. 8)
So what could be a simple tip of you ?
"MODEL IN MAX DUDE !! :twisted: "
okidokay
It’s just that I’m used to a way of working in acad.. though it’s easier in max if you put time and effort in it.. will choose for the last one..
