I am not sure if this is bug or not. Open a model, View->Display Octree, it displays correctly. Model->Edit Position, change position and angle, the model move and rotate as expected, but Octree does not change, still disply the original model octree. undo Display Octree and redo Display Octree, still display the original model octree.

Hi,
Yes, this is a limitation, Octree is not updated when moving object.
The GLC_lib octree as been designed for rigid scene, so to update it I have to delete it and recreate it and it's time consuming.

So I have to redesign GLC_lib octree to animation purpose.
