You will need to (re)compile OSG incorporating the FBX SDK. Then you will
be able to use the osgconv tool to convert models from FBX to
osg/ive format. This recompilation is something that will need to be done

Well, I was wondering if there was an OpenGL RTX API anywhere, but it
doesn't seem there is.
Vulkan would appear to be the way to go for the future, but since that's
not ready for the oven yet (don't even have all the mise en place), it
might be we just have to make a utility library to shovel OSG

One of my guys pointed out this recent addition:

If anyone spots an Nvidia demo that shows some OpenGL / RTX int
I think it used to work. Strange. I am not where I can test it right now.
Can anyone else confirm?

Hey Rob (Lockyear). You know, Mike Weiblen has already done this stuff
you're doing in OSG. Last year, I put him in touch with Matthew Hamilton
and Russ Baker an email suggesting you guys all mind-meld to see if his
wisdom could save you all some effort. Perhaps they didn't know he was

Normally, no. OSG's underlying Group system allows only one LOD to be
drawn at a time, though lower LODs are actually retaine
I don't have any modern Apples to Apples comparisons to cite.
I do know, that if you recall, we ran into threading issues when dealing
with the massive plenoptic display IG back in 2015 or so on AMD cards, and
it needed special assistance from AMD to unclog it.
Do you know Graham Sellers at AMD?

This usually means the plugin was not found or failed to load.
Can you trace with something like SysInternals tools and see if the DLL
file is found and what other dependency files it might have tried to load?
