Hi Ted,
Or, it is if the Camera keeps getting 'pushed' further away as the object is being displaced.
I remember seeing this too. The trick is not to track the MatrixTransform itself, but to track its child (if there is no unique child, then reformat your graph by creating a single osg::Group below the MatrixTransform that contains the MatrixTransform's old children).
For some reason when you setTrackNode(some MatrixTransform) the transform's matrix is applied twice which is what I think you're seeing.
Hope this helps, J-S -- ______________________________________________________ Jean-Sebastien Guay jean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
