Interior with Only Daylight System

[Jet]

This hopefully will help me with this whole light leak thing.

After doing what i thought was a perfect model, i set up the daylight system to light an interior right. Light leaks.....

i move the sun around and light leaks followed by moving to other locations

which tells me that the modeling was fine. well i take that same model and use photometric lights in fixtures and without fixtures, and not one single light leak at all. What gives? its pretty confusing, but i have seen too many renderings on here that use only a daylight and there are no light leaks, perfect images. Any help on this is appreciated. and comments as well.

I assume you are using Max with radiosity and daylighting system? What are you using to model with? I use cad, and I never have light leak problems. I believe Strat and Fran would be able to answer better, but here is my two cents. I could be wrong, but try upping the refinements, and set ray bias to .1. You should post some images of the wireframe, and rendered image. There was a post similar to this a few months or so ago. Try looking into it.

are u using area shadows ? if so under the area shadows, make the shadow bias set to 0.0

I get round this by wrapping a box around the model with openings only to correspond with openings in the interior. You could work as accurately as you like in Max but there is always a little corner somehwere that gets leaky.
