Metallic material default diffuse color is white while in Blender plugin or Standalone it is Black. This leads to unexpected material differences when importing materials to C4D from ORBX files.

Tested on latest versions 2018.1.x

Steps to reproduce
1. Create Metallic material.
2. Change Specular map value to 0
3. Material is White. Same situation in Standalone or Blender plugin, material is Black.
4. Diffuse color (Metallic material) in C4D is white in standalone and Blender it is Black

Example material where the dots should be black in C4B but are white. Specular map is a texture it this case.

Because SA is not adding any node to diffuse slot. I think it's not a big problem to change to black.

It's not a problem to change it to black, but users expect that materials will look the same in Standalone and in plugin. I lost some time until I realised C4D plugin interprets this setting differently.

I'll change the default diffuse color to black for metal.
