The possible errors are due to an inconsistent use of the number of
columns or rows as related to resolution. Leave it for the moment, I
appreciate you are busy and I am not expecting help. When I post an

Is the setText being called from the cull or draw traversals? If then
this will cause threading problem. You should only modify the scene

In what way is the rendering not what you expect when you use

are some difference in OpenGL state or the depth of the colour buffer.

Yes, I agree that using the CameraNode would be easier and more efficient

If you have a large group and you do not want them to be handled as a single
LOD, then don't put an LOD at the Group level; instead, put it at the
sub-Group or Geode level.
