Hm, this mtl file has emmisive / Ke as a single value:

newmtl shield_Mat
Pr 0.0),
Ni 1.6
Ka 0 0 0
Pm 1
d 1.0
Ke 0.0

Afaict this is supposed to be a color [3 components]?

Not sure if they [adobe] are breaking the specification [not sure if this is even in there officially...wikipedia says it is an clara.io extension]
[btw. that roughness / Pr line looks a little suspicious as well ;)]

@mont29: would be easy to check the line for 1 or 3 values (and act accordingly), could do that, question here is just [again] if we are adapting to custom flavours?
