You may want to try setting an initial bound on the auto-transform as
well.  I've run into problems in the past where the auto transform is
culled because it begins with an invalid BSphere, making the culling
visitor think it is small, so it gets skipped and the actual BSphere
never gets computed.

This sounds familiar, I think I ran into it a while ago. If I remember
correctly, we worked around it by disabling culling on AutoTransform
children.

        Subject: [osg-users] Bug: Autotransform and smallfeatureculling

        Hi,

        there is a bug when using the autotransform node in connection
with small feature feature culling.

         

        We display icons on a globe using an autotransform node per
icon. By default the icons scale/orient nicely when moving the camera.
However when moving the manipulator into the home position, the icons
get culled away.

         

        The problem is that the cullvisitor autotransform computes it's
bounding box after computing the scale required to display the subgraph.

         

        Any ideas on that?

        Richard
