Hi,

I'd like to render a realistic scene with terrain shaded based on the
actual sun angle and a Alpha cloud that you can partially see that
terrain through.

1) How hard would it be to handle the sun angle effect?

2) Why can't I see a solid surface through an Alpha rendered field? What
is the potential for this to be corrected?

Thanks,
Doug
