[Radiance-general] obj2mesh and materials

[bob coyne]

I figured out the problem...I put the "-a <materialfile>" option
after the input .obj file rather than before it.   It didn't complain, 
and I didn't
notice.

I switched them around and it works.  Sorry for the false alarm.

One other question.  Is there a way to override the values
of materials on individual groups in meshes?  I'd like to override
them individually from the outside so separate instances can have
different attributes.  I don't want to have to create new meshes just
to change some materials on groups.
