Hello,
I'm facing weird problem, I try to render cast shadows from invisible trees through a windows.

I cant get the shadows if Visible to refraction/reflection isn't activated...

See fig01 : all enabled > the floor shadows are visible
See fig02 : not visible to camera > also
See fig03 : not visible to camera & ref/refraction... > no more.

There is glass on both windows and door, except in the middle (see purple tree visible fig04).

What happens ? Why cant I get only the floor shadows and no visibility of the trees at all.

Thanks !

JG

you can try to use corona rayswitch material for your trees with only GI slot enabled

Hi, I've come across this problem before myself, and I believe the "fix" is to turn on "Thin(no refraction) on the window material and leaving "visible to refraction/reflection" turned on, on the trees.

I'm hoping that one day the Corona team could work on fixing more of these fake things we do to simplify compositing etc. Like "reflection planes" casting shadow even if "Cast shadows" is turned off.
Or maybe I just haven't figured out how to do it correctly :P
