That texture should be a glass with 'portal' checked.

This is new to me.

Do not know how I missed this one.

 

Thanks for the tip.


It's a bit sneaky, but can help environmental light spill properly into a buildings interior. I use it for all exterior glass. Theoretically it makes environment lighting calculations a bit slower, but i haven't noticed a dramatic difference in times, just quality.

I find it helps most when I have a situation where I get those little light spots on flat surfaces and in tight corners, sometimes called fireflies. There are a few other things that can cause/mitigate them as well but Portals is one that seems to fix it when I have a large or nooks-and-crannies-filled indoor space with no light sources inside.

HEY KEVIN,

The "portal' option is in the texture definition, Click the "Indirect Lighting Options" button and check "Portal' to allow lighting/indirect lighting/environmental lighting to pass through the glass texture.



To clarify for anyone else reading: you do not NEED to enable that setting in order to get transparency, it just assists in letting environment lighting pass through a transparent object. Simply giving the glazing class a transparent texture should be enough to answer the original posted question.
