[alikashan]

i cant figure it out without window glass room is rendering ok but when i put a window glass my sky goes away?? i have images attached. i m using physical camera and sun/sky feature. glass window has the same material as glass blobs ?????

any ideas:rolleyes:

is the glass in the window part of a multi-sub object material?

[alikashan]

nopes its not ???

[pg1]

vray has a bug where glass as a multisub object doesn't render correctly

 

check the affect alpha box

 

Select the glass layer and turn off visible to GI in vray properties

 

Also I read this in another post

 

I remeber that I read somewere that to let the light pass correclty trough glass wall you had to check (in the GI -Indirect illumination- general settings) the GI caustics to reflect and refract, doesn't matter if you don't check caustics on in the caustics tab.

the problem is with vray physical camera i dont what exactly but it rendered correctly with the normal max camera. in this scene i just reduced the sun multiplier.and i m using standard camera. what i m doing wrong with the phyical camera any thoughts.

ok i found out i was using a hdr in my reflection slot that was creating the problem now its working just fine.
