Links with Multiple Visual Elements with Different Colors Don't Render Correctly

[TimCraig]

Using RViz 1.12.15, if a link has multiple visual elements, the first visual element renders with the specified material color. The remaining visual elements render as black. The model I used was processed with Xacro but I examined the generated URDF and the materials were specified correctly for the link.

@TimCraig could you provide a reproducible example? That will help this be investigated, thanks!

@dhood Here's a simple file with two links and one joint. The base_link has 3 visuals each consisting of a cylinder 1 meter tall and half a meter in diameter spaced along the x-axis. They should be red, green, and blue. The green one, in the middle which is listed first, displays properly while the other two show up in RViz as black. I've included a screenshot. Running ROS Kinetic on Ubuntu Mate 16.04 in a VirtualBox on Windows 10.
