I created a headdress model in Blender and it is weight mapped to the head (first Image).
When I import the headdress into CC it is set as hair but I want it as cloth so changed it. (second Image)
However, when I activate the appearance editor on the headdress it is still treated as hair and not cloth (third Image)

I want the headdress as cloth so I can set up an RGB mask for texturing different sections of it in appearance editor the same as cloth.
I have used RGB masks on many of my own CC clothes (that I have created in blender) with no problem so I have an Idea how to make them correctly.

I also saw that the headdress, with its hair style of the appearance editor, the Input section also had an RGB mask So I added the RGB mask I created for my headress to it. However, going into the Base, Primary(Red), Secondary (Green) doesn't seem to do anything when changing the settings in there.

Just to clarify this. I have made quite a lot of clothes and have had no problem getting them to work. Its only when the cloth item is weight mapped to the head CC sees it as hair and changing it to cloth while importing it doesn't change how CC sets up the appearance sections.
They are the same as hair and not the same as cloth (see third image)

EDIT
Is this a bug? I don't know?
Maybe I am missing something but I have tried it with a dozen variations and it always does the same thing
