invisible wall but with gi?

i have to do an interior shot of an small room with but with 40mm-camera, so i have to put the camera OUTSIDE the room. but how can i hide the wall “in front of the camera” and its windows but make them influence the gi and reflections of the inside?

maybe try to make the wall and the windows seperate object and uncheck “visible to camera” in their properties - dont know if vray respects that setting though

Hi Mattias,

Have you tried camera clipping? I know Vlado used to say it could cause problems but I have used it loads of times without any mysterious red/green dots appearing.

mike is right!

worked for me!

Clipping absolutely… untill now zero problems..

i thought the dont render option also worked. worked for me once when i had to take the roof off of a building to get a top down view

hey, thanks a lot - clipping seems to work nicely. didn´t think it would work that easy. gi-bounces from the “invisible” wall works fine, but i still didn´t try the reflections from the “invisible” window. might be another problem…
