I've exported my subgraph to the .osg format, but it wouldn't load in osgviewer
(possibly since it's a camera?).
I've looked at the exported file in a text editor, but it looks to me like
everything has vertices, colors, and normals as they should. Could someone with
more experience take a look? Am I missing anything here or have I set something
up wrong?
In your original post, you said you weren't using Material colors. But in the
.osg file below, you *are* using Material colors, and they're set the same for
both objects. Lighting is on by default in OSG, so that's why your objects are
rendered in the same color.
