Hi Taufux,

 

A few questions - what is your lighting setup, how many lights are you using and what shadow type is selected? Do any of your lights cast shadow and are any attenuated?

 

Could you take a screen shot of your lighting setup for a better idea?

i'm not really understant wat u mean by attenuated?

Hi Taufux,

 

few suggestions on your image:

1.You dont have to use 8 lights if your using viz 4 radiosity maybe 2 or three will do.

2.you may use logarithmic Exposure control for good shadow calculations.

 

what Initial quality value did you use?

what is your meshing size?

hello James

 

i use 2300lm for all the lights n overall mesh is 300! but if i use only 2 or 3 will it be too dark?

 

ya i currently using logarithmic Exposure for that scene also! :angesigh:

ok i have change some setting on this image already which:

 

initial quality : 75

meshing size : 300

Radiosity light : 3

Maybe adjust the midtones? brightness level in logarithmic exposure? or tweak in photoshop? i also agree that u dnt have to use 8 ies lights.. in the real world (which radiosity is supposed to mimic) you wouldnt use 8 lights to light up a space as small as this..

if using just 2 lights would darken this scene, try upping the brightness level to compensate. this way, your scene would not come out washed out.

 

hope this helps.
