Hi Guys, We're running into this issue as well, and I'd agree that to synchronize what the artist sees in MAX with what is rendered in OSG, the scale by 9.99 should not happen. Currently the MAX specular level of 999 is required to get an OSG specular material value of 1.0, which means the object is "glowing hot" in MAX, and normal looking in our OSG app.
This change would also allow the artist the range of 0.0 to 9.99 in the OSG material, so they could oversaturate it if desired. I'm also of the opinion that the exponent shouldn't be scaled from the MAX (0-100) to OSG (0-128). It's just the exponent for the specular contribution. I'd personally trade consistency between the authoring environment and our OSG app for losing out on the exponent values of 101+ (which we aren't using anyway). So I'd propose that this code in MtlKeeper::createMaterial(...) remove the divide by 9.99 from the setSpecular() call, and the setShininess() call multiply by 100.0 instead of 128.0.
