Color.Raytraced does not render correct material colors

Hello,

The new Color.Raytraced baker does not render the correct material colors

It worked correctly in v14 but chooses random colors in v15.  

Additionally, Color.Raytraced does not function correctly through the SAT.  If left to the default, or set to mesh_color through the --color_source flag, it renders a black image.  Example command:

<path_to_baker>/substance3d_baker.exe Color.Raytraced --inputs <path_to_low>\low3.fbx --output_path <out_path>\ --high_scene_paths <path_to_high>\new_colors7.fbx --output_size 1024,1024 --output_name ID_Test --padding_radius 10 --projection.max_height .5 --projection.max_depth .5 --color_source mesh_color

Assigning vertex colors to the high poly fbx and changing the color_source flag to vertex renders out the vertex colors correctly.  I have tested most of the other bakers through the SAT with no issue after updating the new flags, but mesh_colors seems broken both in Designer and through the CLI.  Please advise, I have multiple tools that rely on the ability to bake out correct material colors as IDs.

Thanks,

Chris
