Hi Judd,
The core OSG does have a FadeLOD feature. One can implement it a
higher level but its a bit awkward.

One approach is to use shaders for fading. Here's a simple example:
https://wush.net/websvn/osggis/filedetails.php?repname=osggispath=%2Ftrunk%2Fsrc%2FosgGIS%2FFadeHelper.cpp
Of course you'd need to augment the shaders to support lighting, texturing
etc., but you get the idea.

Thoughts...
Fade-LOD is an interesting feature: the concept is to smooth
transitions between LOD switches by rendering two adjacent LODs with
varying transparency to minimize visual popping. However, the whole point
of LOD is to control rendering load, and Fade-LOD *increases* rendering
load
Does osg support or has anybody implemented fading between LOD
transistions? I found an old thread where someone talks about it but no
word if anything ever happened with it
