I'm getting the same issue with swatches.fbx from Quixel Suite 1.8, but with Blender. i.e. in the swatches provided for photoshop (Swatch.aco), the color for Varnished Wood is #c85300, but in the FBX file once imported into Blender, the color is #E59B00 which results in "Undefined" in Ddo. I converted swatch.fbx to ASCII…
