hi everyone.

criticisin it myself.. i actually have only one large window in this room but jus applyin light on tat area doesn brighten up the whole room so had to make do with another light which isnt natural.. is ther ways to light the whole room otherwise. tried increasin environment but eveythin looks odd.

 

apart from tat few black spots seem to have appeared. dono y.

i used adap qmc, mitchell, used ir as prime n qmc as secondary. i used medium presets for irr. ( customs values seem to confuse me. need help in tat dept too! )

took 7 hrs for 2000x1500 output on a p4 1.5g sys. is this normal?

 

please do point out wat else is wrong n requestin ne kind of help.

 

thx in advance.

Usually the quick way to render these typical scenes is keeping the default setting of the Vray. Because increasing the value of brightness with more intensity lights (sun or sky) take a long time to rendering, so you can bright a dark image with adjusting the color clamping settings. Enter 5 or higher value for dark multiplier and use hsv exposure control.

these are the settings and a top wire to show position of lights.

Try Light cashe for the secondary bounce and turn on use light cashe for glosy rayes in the light cashe rollout. this should bring render times down. Also serch the forums about working in liner space becouse if i'm right you have 8 or 9 lights and that's too much and that's what's kills your render time. With LWF you can reduce the nuber of lights dramaticly and get much faster renders.

Sorry for my English,

thanks u guys.

 

shiftin to light cache reduced the time so sharply! rendered the same scene, same reso in 1.5hrs flat. qmc took 7.5hrs! y is it so. i shifted to exponential too in the colour mappin.the black spots dissapeared too,. think tat helped a lot. man sometimes these thins are too confusin. irr is one thin ill never understand! used min to max of -5 to -3.

 

neway hopin to imrove..
