VrayLightMtl doesn't emitted to near object

[andyzhang1]

Hi guys, i'm new here,, and my English not well so i'm sorry if there any unclear word, wrong grammar etc..

I've a problem with VrayLightmtl, When i render using Vray Phys cam,, it doesn't emitted, I already click GI on ..

I set the colour to yellow,, but the output colour is white,, using Vray 1.50

Anyone have the solution?

You mean you switch GI on in the render settings, or do you mean you ticked "Direct Illumination" in the LightMaterial?

 

VRay 1.5 lacks some nice features that the newer versions have. For example from version 2 upwards, the liht material has an option "compensate camera exposure" which is VERY nice.

 

However you don't have that in 1.5 so you will have to do one of these 3 things, or a combination of all of them:

1. In the light material, adjust the multiplier

2. Adjust the colour

3. Change your camera exposure

 

There's a bunch of things that can influence this, for example are you using camera exposure, LWF etc,

 

Without some screenshots or more info, we're just guessing here

Thanks for your answer sir,, here is the photo

 

U can see behind the TV,, there r light, i use vraylightmtl,, don't know why it doesn't emit well,, same on the bot side of cabinet too.

Now im using 3ds max 2009 and vray 2.40.03,, if there's any wrong setting,, plz tell me..

i already ticked Direct illumination on VrayLightMtl..

*sorry bad english

UNTICK direct illumination for the vraylightmtl, it creates extra noise which requires higher setting to get rid of it. Increase the multiplier to make it brighter

 

OR just stick in an actual VRaylight instead
