hi guys…im having some serious problems with my rendering
dont know but look at the corners and the uper wall…they sucks
can u pleas help me in this one…?
hmm…i forgot to tell you the rendering settings
First bounce Second bounce
1.0 1.0
Hsph.Sub 90
Interp.Samples 80
Global photon map for secon bounce with bounces 15
ticked convex full area estimate and Retrace Threshold 0.0
Color mapping : HSV exponential
dark mult : 1.2
bright mult : 1.0
cheers
hi …turn your imap bounces down to 0.7 each …
turn your Interp.Samples . from 80 to around 20… render that for startes and see what happens…
it looks somehow like the geometry doesn’t fit everywhere..
but try natty’s settings first.
hi…thanx i tried ur settings natty and this is what i got 
when you decrease your mult. you have to increase your hsv-dark-mult.
and i think, he meant the following:
First bounce Second bounce
1.0 1.0
to
First bounce Second bounce
1.0 0.7
well no … 0.7 and 0.7 should be enough for interiors … all depends on your lights and settings ..
it doesnt look as if he is using any vray light…but just a direct light … which is no good.
nope natty ur wrong..im using 2 vray lights in the windows
i dont know why but the uper wall its still dark and the artifacts are still in the corner..
can anybody tell me what to do…??
can u post your settings(all)and light’s too??
or u can upload your scene somewhere.
well you need to force more light in there!..
I didnt say you wasn’t using vray lights …but it looks like you aren’t … meaning that you have no control over your lighting.
yeah, i also would like to see your settings at all, just as maxer said.
or upload your scene.
well natty, 0.7 ; 0.7 might be enough for interior shots, but as you can see - it’s quite too dark, thus i suggest him to increase the first mult. i also thought of the lack of vraylights.
but it seems, that the vray light mult.s are MUCH too low. maybe a setting-mistake? i would try setting them each to 1.5 with no decay clicked. and then refine them.
but show your settings and i’ll promise you find some awnsers to your questions as well.
ps: please adjust your displacementmap of your carpet 
yeah post your scene.
its all about light control … 0.7 is enough … always has been …
it depends on the glass strength, doesn’t it? if i’ve got a high absorption-glass as windows, my vraylight won’t pass through enough, so i need to increase the first multiplier, because this won’t break up at my windows.
or am i totally wrong? i also use something about 0.7 - 0.8, but i think, 1.0 still makes sense in some situations.
of coures it all depends on scene to scene… but i tend to exclude the glass from the vray lights these day’s … makes life easier..
often me too, but sometimes it’s necessary, when you’ve got a background in your scene. 
well, anyway, i propose to come back to topic.
yeah …smooth post your scene …and well see whats up.
hi..thanks for replays…these are my settings
and here is my last render…still the artifacts and the uper wall is
too dark 
do your lights got a high photon count? if you use “global photon map” you have also to check the photoncount of your lights.
also set your search dist up to 60 or sth. like that and your max bounces to 0. (dunno why - i do so and it works best)
do you mean max Photons to 0 ?
