Hi Jason,
The good old days... :)
Thank you so much for taking the time to spell it out for me. It is very
helpful. Now at least I have somewhere to start.
Take care now and have a great weekend.

Thanks I was hoping to avoid reinventing too many wheels.
OSG already has code to find a plugin by name, create nodes, receive nodes.
I just needed some examples of accessing a node directly through the registry,
getting back changed nodes and passing/receiving extra data.

I've seen your submission. I downloaded the FBX SDK, but I guess I won't work
on it immediately. Maybe in 2-3 weeks? Anyway, I'll make appropriate feedback
when needed.

Now osgAnimation is supported by FBX, my hope is that other people will soon

have the same effect as forcing COLOR_ATTACHMENT

Hi Ufuk,
disregarding the follow-ups regarding mipmapping:
you're saving the original image. The scaled down image is 'cimage', not the original
'image'. Change the 'writeImageFile' to use 'cimage' and you should be good.

The osg::Shapes/osg::ShapeDrawable really aren't written to be used
for general geometry/scene construction. osg::Shape exist to help

The tool to use is osg:

I must admit I didn't test istreams. I'll do that testing. Do you think testing

Hi Markus,
These methods are in the svn/trunk version of the OSG/osgManipulator,
