Can you show the actual material room so that we can see the "Material" zone area?  Are there any other selections listed in there, like you see in my screen capture for James? If there are something about feathers, then select just that material zone to apply the colour.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
