Infrared camera not capturing model texture

[blakermchale]

I've been working with AirSim and I added an ArUco marker to the environment. I can see the marker fine with the color image, however when I try to view it from the infrared camera it just becomes one solid color.

Is there something I need to do with the material I created to get it to show up in the infrared camera?

By the way, I created this marker by converting a png I had into a material and applying it to a plane.
