work in progress.....need comments

[cristoforo]

I'm beginning to believe that exterior views are more difficult than interiors! Need some help and comments here! What is going on with my glass....it just does not seem like glass. It is not reflecting the enviorment at all. I have reflect at color 176 with frensel on and IOR of 1.6 and max depth of 20. Refract at 187 with IOR of 1.2 and max depth 20. affect shadows is on.

For reflection ior I usually use 2.0-2.4 maybe not physicly correct but it looks nice. I also often put an output map in the reflection slot and turn it up to 2 -3 gives sort of an hdr effect to the reflections.

I'll give it shot!

For the glass, I recommend turning the reflection color to white or almost white, and then fresnel reflections, and then maybe fresnel IOR to 1.8 to 2.0.

Your glass is probably too opaque. In refraction try a light blue-greenish color, maybe RGB 225,241,239 or so. This will keep your glass from looking frosted. I would leave your refraction IOR at 1.5 or 1.6 which is accurate for glass. (this assumes of course you have a realistic thickness for your glass: 5 to 10 mm). Glossiness should be at 1.0 to prevent frosted/etching effect as well.

Also, to pick up highlights you may want to drop your reflection highlight glossiness to less than one. If you have no highlights from the sun or fill lights, I recommend using a quality HDRI in the environment slots... at least in the reflection/refraction environment slot.
