Billboard background as reflection, but no shadow casting

[artchung]

Is that possible to set a billboard as reflective background, but not casting shadow on the model. I tried to set the image not casting shadow in Sketchup. But it still does cast shadow. I tried so many different ways, but still doing that.

Anyone have any hints on doing this?? thankyou!!! Appreciate your advices!!

I'm not sure how to do what you are looking for, but I've revised my post on billboards to show the effect of the shadows from this technique.
The only way I can think to do what you want is to put an image in the 'environment' slot - but it can be tricky getting it to look right, or PS it in afterwards.
