[Radiance-general] Trees

[Tim Perry]

I would like to model trees outside buildings in my Radiance runs. I would like to model them transmitting about 20% of light and make the canopy 40% reflective.
	* Can I do this by using a translucent material? 
	* If so, can you point me to a tutorial?
	* Will this be compatible with the 3-phase method of daylighting analysis? (I.e., daylight coefficient method with the 3-phase method and a BSDF for the window).

Thanks for any help,
Tim
