light through windows

[conceptdesign]

Okay tried all the tips and must be missing something - I am trying to get the light to shine through the windows and into the interior without actually lighting the interior when I remove the roof - I have set the roof ans 2 exterior walls to not visible by camera and unticked visible to gi - I am getting alot of artifacts with the roof and walls turned on - with it off it is very clean - am I missing something? the objects have mapping coords and materials - any help appreciated

Thanks

ok, what you have to do is this:

1- In the glass material make sure you have "affect shadows" turned on.
2- On the roof and wall's object properties turn "visible to camera" and "visible to reflections/refractions" off.
3- (opcional) You might want to take GI environment multiplier to 2 or 3, or may be put a vray light over the roof (with the roof on "exclude" in the light options) to lighten the interior a bit more.

that is it.

Don't forget to use exponential on color mapping type, and try all this first on a new scene, that is because you may have touch something, like object GI and such and might get unwanted results.

Good luck.

with "visible to reflections/refractions" off the interiors had a dark loss of GI I solved this by unticking visible to GI under vray props

looks like an over lapping faces issue. One thing you could try if your using the latest build, is adjust the Secondary Rays Bias to roughly 0.001 and see if that helps.

BTW Secondary Rays Bias is under the Global switches in the lower right.
