Hi,
I have had some problems with OSG freezing when running in
ThreadPerCamera mode. My problems
were resolved with two changes:
The first one changes the order of the startRenderingBarrier and the
reset of the endDynamicDrawBlock.

Hi Sukender,
My guess is that the problem is not related to the bin management,
rather missing vertex colour or vertex normals on some of the
geometry. If it's not this then perhaps you have transparency issues.

If the cow shows and the cessna does not, it is probably an optimization

Shots in the dark:

Strange artefacts indeed, but I still don't think they are render bin related.
There looks to be an issue with state leakage, such as with my

Hi Vincent,
The bounding sphere of transform is in the coordinate frame of its
parents, the children of transform will be in the transformed

disadvantages.

I don't really know where to start because it's not just the API that
you need to know about it, it feels like vector maths and general

Transform are no different than any other nodes in the scene, you can
use the node->getWorldMatrices() method on them
