lights

mga sir,
 what is the right intesity in vray light:
Plane 
mesh
dome 
sphrere????

None... it depends on your general settings, such as the environment lights and vray camera too. if you adjust the shutter speed and film speed it will affect the brightness and darkness of your illumination from lights.

your eyes/visualization will dictate if it is the right intensity of light already achieve.

show your work to your friends and other cgpnoyians here so that they will comment if your lights where too bright or under exposure. 

agree ako kay sir i3dness

tips ko lang sir, mag set ka ng lights mo na comfortable ka sa value, like 1-10 then test mo pag madilim or maliwanag masyado, sa camera settings ka muna mag adjust hanggang makuha mo yun gusto mo combination ng camera settings at intensity ng lights mo 

ganun pa rin render ko mga sir, parang brownout na hindi nka pagbayad ng ilaw, imagine nyo yun mga sir ganun ang render ko, at yung tv na vraylight mtl hindi na nag goglow, panu kaya to? ies light power all 20

Sir,
Basta sundin mo lang ang mga advise ng mga CGMaster at ang mga Tutorial makukuha mo rin at tyaga lang sir.

try to test render without using vray cam (use standard cam lang muna) then pag na tancha mo na yung tamang light intensity/multiplier na suitable sayong preferences,,, then you can try using vray cam, if ever gusto mo I control ang
lightness/darkness/intersity ng scene just like using a real camera. 

Can you try to load defualt visop and render it again. Hope na may makikita ka na konting liwanag if ever. 

Create ka ng light sa likod ng camera mo or outside the window.
Try to tweak your camera setting shutter speed lower it / film speed taasan mo     ng value.
You can adjust also your size of the sun in environment setting. 
Try to render.

ito po mga sir ang tinutukoy ko w/ vraylightmtrl pero pagnerinder ko wala na yung glow, kindly advise me na lang kung bakit nagi tong black and white pero meron syang ilaw na plane light,,

yung mga tanong mo tungkol sa light...lahat yan dipende sayo....every renderer has its own style using those lights. tips ko basa ka ng photography book kasi nag tuturo sila about lighting composition. ma aaply mo yan dyan.
