matte object

i just recently found out that when i check “matte object” and “shadows” in the vray properties the only thing the object does is receive shadows.
is there a way to have it cast shadows too?

in my special case i have a mountain-like terrain and a few small buildings situated in it.
when i use the terrain as matte my lighting solution is wrong as the terrain would cast shadows on itself and the buildings.

best regards

Hi,

Probably disabling the option “No Gi on other mattes” is what you need to do in your setup.
Here is small example how it should looks like at the end.
