The color scheme shown is wrong in the viewer after translation of a zip file( containing .obj and .mat )

I have an obj file & a material file for it that defines the color scheme I require. When I zip these two and send it for translation and view the translated model in viewer I can see the colors are not the ones I am expecting. When I open this obj file in Meshlab I am able to see the colors correctly.

  • Below are my .mat file contents(materials) that obj file uses.

    when I removed the comas color scheme started to work as expected.
