Robert, We are using getOrCreateStateSet()->setRenderBinDetails. What we have is this:
osg::group1->osg::group2->osg::group3->osg::geode->osg::geometry, where group3 contains multiple geode->geometry children. group3 has setRenderBinDetails called without specifying INHERIT_RENDERBIN_DETAILS, Which means it is setting to USE_RENDERBIN_DETAILS by default, correct? geode has setRenderBinDetails called, specifying INHERIT_RENDERBIN_DETAILS. None of the other stuff has renderbin details set in the statesets, HOWEVER, there may be other statesets in the chain that do exist (I call getOrCreate). Maybe they all exist regardless of whether I call getOrCreate, but I am not sure of this. The geode/geometry subtrees also have a texture associated with them. They also have GL_DEPTH_TEST disabled, so that we should see the most recently drawn (highest renderbin #) when two geometries overlap or would normally conceal one another. This is not what's happenning however. Any ideas why this might be the case? I have been over the code and I'm quite sure that I've described the situation more accurately.

StateSet::RenderBinDetails is what should be used to control overall draw order, but you make not mention of this. Robert.
