Hi,
In the implementation of a Drawable subclass, I am trying to use regular GL
functions to render primitives through vertex buffer objects. Like so:
Init:
Code:
Drawable::Extensions* ext = getExtensions(state.getContextID(), true);
GLfloat v[] = {
0.0f, 0.0f, 0.0f, 1.0f,
2.0f, 0.0f, 0.0f,
GL_CURRENT_RASTER_POSITION_VALID is returning false,so I assume something is
happening in the projection matrices. Any ideas?

I don't know what is up with your code, but using dynamic_cast to a

Hi Mathias,
I don't what the problem is, but the OSG uses lazy state updating that
is managed via osg::State, so there is a chance that state set
elsewhere w.r.t vertex set up is effecting your drawable, or the other
way around.
Robert.

so you are saying you see the images blended but still getting a

Hi JP,
it is important to have the texture lookups instead of setting some values
for the shaders in the code. Mix works in general, so when you setup values
in the shader you get proper results. But when you do a lookup for a 2D
texture and CubeMap generated on the fly, it doesnt work.

Any clue what is going on? The sample code is with this scenario:

I swapped the texture units: pass unit 0 to createShadowedScene() and

The crash is in MergeGeodes in both 2.8.2 and svn trunk head. I can

Hi Robert,
It's got an OSGDB_EXPORT declaration, but it's a template so shouldn't
