I've only just started using the Archicad render a couple of days ago.
While it shows a lot of promises i am struggling a bit trying to get the right setting. One issue i am having is with shadow casting. I've done a few test renders and they all have very grainy shadows. Would anyone know how to set the shadow quality up? I tried fiddling with minimum and maximum samples under the shadow casting setting, but didn't really fix the problem..
