Hey friends,

Like various others have said before, I'm trying to create an invisible shadow-casting object to make up for the shadow casting limitations of the 2d trees I am using. I've read the previous threads about using a transparent PNG as a texture, but I have (for some reason) never been able to make this work. I've used PNGs with 0% opacity, PNGs with 1% opacity, I've tried TIFs (though I think SU doesn't support transparency in TIF?). I've even downloaded Gaieus' 'transparent buildings with shadow' example component from the warehouse (http://sketchup.google.com/3dwarehouse/details?mid=779b98e58f0afd42cb6ac4bba1570c24&prevstart=0), and every time, my PNGs render as white.

I was wondering if there was any obvious reason for this, or some setting I'm failing to enable in vray?

I'm running SU version 8.0.4811, if that matters. Not sure how to check my VfS version #.

I've attached the sketchup viewport and rendered output...

Thanks!
