    Default transparent massing casting shadows?

    If I mass a building and have its material transparent, then it doesn’t cast shadows, is there a way to have it cast shadows and still be transparent?

    Why would a transparent material cast shadows?

    in the case of creating a schematic massing of a building, the transparency of the building would only be a graphic representation so that we can better see its relation to its context.

    PS in reality glass does cast a shadow, its just translucent based on the opacity of the glass.

    Yes, change the material properties of the glass that the mass uses to be something other than 100% transparent.

    when I change the material transparency to any number other than 0% I lose the shadows in shaded views. (This is the transparency slider bar under Materials/Grapics/Shading)

    am I missing something here?

    No you got ti right. As soon as you change the transparence y value to other then 0% it won't cast shadows.

    Hmm interesting. I thought that I have changed the settings before where some transparency would cast shadow...sorry about that!

    I recall that too Scott. I think prior to 2008 there was a 'point of no return' (about 65% if I recall) where transparent masses would still cast shadows. Probably one of the things that was 'fixed' at someone's request
