Environment behind glass

[Sweet Architect]

Salam, to all

i have that issue that confuse me in V-ray, i don't know if i miss sth. but each time i render an interior view and try to put a view in the environment map slot(Rendering:environment) to be seen through window, it's seemed to be dark, even i put V-ray sun outside, and the glass settings is the standard one, i don't know what the problem is:confused:

any suggestions?

if you use phisical camera you must increase your image brightness.

you can do it via output map, or via output settings inside bitmap.

I use phisical camera,f number=4

but i didn't understand how i will reach to the bitmap settings,sorry i'm anew user of max, i teach myself via toturials,so plz be patient while leading me

advanced thanks

ok, know problem

first of all there are 3 settings wich affect exposusre in phisical camera.

1 f numer

2 shutter speed

3 ISO

different combination of this settings gives you differen exposure (different brightness of render)

 

To increas brightness of bitmap for your enviroment, go into bitmap settings and increase output amount (see attachment)

 

Also you can use plane wit bitmap behinde the window.

You can use vrlight material with bitmap on the plane or you can use vrmaterial with increased output amount of bitmap in diffuse slot.

If you use bitmap on plane or cylinder - exclude this geomety from GI.

I did what you told me, i used a plane and change the output amount of the bitmap(by the way i felt stupid when i get what you was mean:o )

however , i follow your steps and i will attach the result, but how i can exclude the plane from GI

 

Thanks for your help:) ,appreciate that

playaround with output amount. it`s depend on your camera settings. you can make it brightness or darkness by yourself

 

to exclude plane from GI (if don`t do it plane will be light your room as vraylightmaterial) just right mous button on it, go "V-Ray properties" and turn OFF generate GI and receive GI properties.
