Raytracing Colored 3D step files

[gridlock2]

Hi All,

I've been working with the Raytracing module to render some component step files. When I see the components in the FreeCAD display window, the colors appear to be correct. However, when I render the components using Raytracing, some of the components lose their color (see zip files attached).

I've tried
File\Import\step file with colors and
Part\Import CAD\Step with colors

but still got the same problem. One thing I noticed was that when I selected a colored face, the "Shape Color" property displays the default rgb "204, 204, 204". When I selected one of the red surfaces, the Shape Color property was correct and the red color was rendered.

Using FreeCAD version 0.13.1828
Windows 7 (32 Bit)

Thanks for any help in advance.
