Hi,
I'm using osg in combination with osgNV+PhysX to simulate physical objects.
This works fine.
Now I want to suppress the visual rendering of the scene and use only the
scenegraph system of osg to simulate the physics without a graphic window
(standalone application). I tried to call the ne

if you decide to upgrade, why not directly to the newest dev relese (2.9.14) ?
Maybe there are further improvements.. :)

FYI, Paul Martz's OpenSceneGraph Quick Start Guide is preferred for

Of course OSG can work well with c#, but i recommend you to patch the block
about osg into dll.
Just by calling the dll can help you easily use it

Can anybody give me any suggestions_

But the problem still exists. There are a lot of triangle and quads which have

1) Adding prefix/suffix to image filename. I believe this is the easiest

For example, you can append "_[normal]" to all normal map images.

This is the index that Camera::SetRenderOrder() takes as the second
