Can you put some images of what are you trying to do "create a decent looking spandrel glass" and "just doesnt look good" ???

collin1182 - I have had similar problems (esp. with the boss comments on glazing). You have mentioned that inside looking out is fine, and I have noticed it is fine looking inside only when you have all glass walls (unlike the samples shown). I have not tryed this yet, but I would assume you could get rid of the "dark glass" by placing something like a studio light on the other side of the glazing. Only problem is that it would increase your rendering time. It just seems if there is a light source on the opposite side of your glass (as in an interior shot) it's not so bad.

no - that actually doesn't work at all! sorry... I do find I have a lot more control with my glass when I replace the material type w/ "Generic" in terms of reflectivity and transparency as well as color.

You have to have some content near by or it will just reflect the blue sky background. boost up your reflection to 25%-35% and add massing or walls near by and look at the effect it will have, also some lights inside do wonders(you need to increase the light strenght X10 to appear in a daylight shot)

start with the "generic" material...it allows you to customize a color, reflectivity, transparency, translucency and self-illumination...set the index of refraction to "air." the built-in glass materials are admittedly not very customizable.

correct me if i'm wrong but clear (or at least semi-"transparent" ) glass does not have a property known as transparency. there is an index of refraction and a reflectance. from these two properties you get what you are refering to as transparency correct? so the index of refraction is pretty much the same for the same type of glass (vision glass is chemically the same except for color) So i am assuming that revit inputs this number and just uses it. You then can adjust the reflectance which can be different. so that means that in order to make a spandrel panel you have to think about how it is working. You need to create a material that is not transparent. use that as a base and then give it lots of reflectance to match the glass. which doesn't work that great because revit makes it splotchy. so now what? well what i do is create a spandrel panel that has a layer for glass and another layer for opaqueness. so two extrusions. one gets the glass color and the reflectiveness. the other makes it opaque. i use glossy paint for the material on the opaque panel. then i can adjust the paint so the spandrel panel looks good and then i don't have to mess with glass. totally awesomeness right?
