Hi Farshid,
Also, as a quick fix, can you try declaring the SetReference method of
OSGHelper in a protected namespace?
Actually, since it's never called by anyone, I just commented it out. It
compiles and exports correctly. Just another data point for you, but is
that method useful at all?
Hi Farshid,
It might be called internally by Max, since it is overriding the base
class method. I'm not 100% sure of this, but it's probably safest to
leave it there.
Seems to me that if it's not in the libs, then it can't be called by
Max... Unless there's a bug in the libs I'm using

You are absolutely right! I had mistakenly assumed that the description

Hi Farshid,
If the new meta-data system is going to support all osg::Object derived

and older formats like .osg/.ive.
Yes.

The exporter applies the material statesets to the osg::Drawable object,

The second method doesn't necessarily need to be an option. I don't see
any harm in always adding a description string to the stateset. My main

I totally agree.
I'd like to avoid the first method, since it introduces

suggestions for how the material description strings should be formatted?
Both your and Luca's suggestions are good, but I think I like Luca's
Hi Farshid,
I personally don't need them, but if a hard-coded texture unit option
were to be added to the exporter in the future, then we might as well
add this information to the description string now. If we are 100% sure
that this option will never be added, then I'm fine with leaving this
