Small Blender Render OBJ Export/Import .MTL Issue

Support Materials and Textures
1

Hello folks!

I was hoping that someone might be able to help and/or clarify a small issue I’ve been having with Blender Render’s Exporting and Importing of .MTLs.

The textures and everything are good and in their place. The values of certain Material settings are what is giving me the bother. As you can see here, I’ve set the Diffuse, Specular and Normal Intensity to specific values.

But here, after I’ve exported to an .OBJ with .MTL and then import it again, Blender resets the Diffuse, Specular and Normal values to 1.000.

Here is the raw .MTL file

# Blender MTL File: 'MustardBottleRender.blend'
# Material Count: 1

I’m curious as to whether the resetting of Values is a problem with Blender’s import function and the way it reads .MTLs or a problem with how I’ve arranged the file and exported.

Or is the resetting of those values just a fact of life with the .OBJ format?

The reason that I was checking in on this sort of thing is that I may be importing those .OBJ files across different software and I wanted to see if I could preserve the values more or less intact.

Hope someone can help!

Thanks!
