Vray IES light problem or material?

[andyzhang2]

Hey guys

Introducing myself, I'm Andy from Indonesia. I learn Autocad and 3dsmax about 3-4 years ago. My rendering now is quite good, thank to all tips and tutorial

(sorry for my bad English)

 

This is my first post here

I have some problem in my rendering and need your help

 

Look at the pictures above, I rendered both scene with same camera setting, same IES setting, but why the pictures with dark material looks different. The IES looks so weak even it have same Intensity. In real world, dark material wont affect the VrayIES intensity, right?

 

Wall : Vraymtl, Bitmap on Diffuse Maps

GI Environment : on, multiplier 1

VrayIES : Power 15.000, all setting is ticked.

VrayCamera : Shutter 20, ISO 250, only Exposure ticked

 

The difference between the pictures above is reflection. As you can see, VrayIES shape is not visible in top pictures, while the bottom picture the IES shape is visible.

 

Top picture : VrayMtl, reflection color 255,255,255

Bottom picture : VrayMtl, reflection color 180,180,180

 

My question is, in real world, do the light visible on mirror ?

 

Render Setup : Exponential, Primary : Irrandiance map Second : Light Cache

 

Is there anything I need to tick or untick ?

Correct my material setting if you think im doing it wrong.

 

Im really sorry for my bad English, you may have some problem to understand what I mean. But thanks you if you want to help me!
