[Bf-usd] Collaboration goals

[Brian Savery]

Those are valid points, I was aware of the open source availability of
MDL.

However, for the purposes of sharing materials via USD, there is more
momentum around materialx than using the MDL schema.  And would argue that
material interchangeability with USD-enabled apps is the important point
here.  Unreal is the only one I know on that list that is adding USD
support, and they have also announced that they're working on MaterialX.

But I totally agree about MDL and MaterialX complementing each other, but
the fact that you can get OSL or GLSL or MDL from MaterialX seems to be
another vote for not limiting to MDL directly.

Wasn't trying to disparage MDL at all!  Just that in this context I think
MaterialX is a path to give users MDL and more.
