Hi Peter
I can't help you with your problem. I am a newbie to OSG, but I'm
actually trying to have a nice (back)ground for our scene and thought
that grass and a tree would look very nice. And I have to say that your
video looks amazing!
Where can I find some helpful information for modeling the grass with
billboards and how did you create the shadows, with osgShadow or a shader?
Thanks and regards
Dominic

Hi osgUsers,
I have question about rendering shadows on grass billboards. This is
not a question about anything missing or not working in
OpenSceneGraph, but a question how to solve a problem with shadows and
grass.
The problem is the grass are created using a shader that creates
billboard instances, so all grass you see in the video are billboards.
When the shadowmap is applied to the grass billboard I get streaks at
certain camera angles. Does anyone know how to fix this problem so the
grass looks more natural on a grass billboard.
Here is the video:
