Quick Luxrender tip:

I apologize if this seems obvious to some people but if it hadn't to you, than it may be helpful ;)

Some of you may have noticed the problem with windows in some architectural sets. If there is only a single sided poly and a glass material is used, Luxrender ignores that area of the mesh altogether and nothing is rendered. Since they're made for Poser, there really is no need for windows with thickness, so a single one-sided poly will do. Luxrender however, has problems with this. If you're not adept with a modeling program, there's a way you can fix it in Poser if the windows are in a wall.

Load a single sided square from your Poser primitives folder. You can use just one for a whole wall of windows. Scale it however you need to so that it's slightly larger than your windows. Place it just a smidge behind the polys in the window. It may help to switch to top view and wireframe to do this. When your single sided square is placed, rotate it 180 degrees on the y axis so that its normal is pointing toward the outside, in other words, the opposite direction of the normals on the original window mesh (for an interior scene, the original window's normals will be facing inward and for an outside scene, they'll be facing out. Either way, the original windows normals will be facing the camera. You'll need to make sure that the normal on the single sided square is facing away.

When you run the Pose2Lux exporter, simply assign the same glass material to the single sided square as you do to the windows in your model. Luxrender will now render glass there :).
