Shadow Help

[seasdes]

I have a architectural model where I have a roof that I want to be able to see through but I want the roof to be able to cast its shadow. There was once a post on this topic but I cant find it.
Can some please advise me how to do what I ask in the first sentence.

Thanks for your suggestion Charlie. The link you provided is not the one that I am after.

The link that I am after has to do with the properties of a material that will allow what I am after to occur.

you can achieve this effect by using a 100% transparent png texture with just one single colored pixel in it.

Here is one in .skm form.
Just drop it in your Translucent materials folder.
