Hi Brede,
 
I know rendering options in the comment field is not part of the OpenFlight
specification.  But, the old loader would read the comment fields into
description field of groups/objects.  This allows one to write a node
visitor that does use the comment field to do rendering things not in the
OpenFlight specification.  Using the comment fields to extend OpenFlight
files has been a common method used by many.  Since comment fields are in
the OpenFlight specification, it would be nice if they were preserved in the
scene graph, or at least an option to do so.  You know what I mean?  I can
do this at a later date.  I know you put a lot of work into the new plugin,
so I want to help as much as I can.
 

Zach

Hi Zach,

The new loader doesn't try to be clever.  E.g If your flight file specifies
a lit face without normals thats what you get.  By default the OpenFlight
loader performs some optimizations to give better performance out of the box
(osgviewer) but this can be disabled with the reader option "preserveFace".
Rendering options in the comment field is not part of the OpenFlight
specification. 

Without a model I can only guess but you could try to perform a "calculate
shading" in Creator to regenerate normals.

Regards,
Brede

If I turn off lighting, the new plugin looks similar.  However, I use the
comment field to add additional rendering parameters to flt files.  This
does not seem to be getting into the new OpenFlight plugin.  I'm assuming
the new OpenFlight plugin is ignoring the comment fields.  When, I get some
time I can take a look at adding this.
 
Anybody know why the new OpenFlight plugin is rendering the scene darker?
Is something different in normals?
 
Thanks.

I've used the old plugin until some weeks ago. When caching of textures was
implemented, i migrated to the new plugin. And as far as I have experienced,
it works great.

What is not converting correctly?
