i dont know if this one works or you read it or tried it but this is how i change normal character hair tyle: right click on the character or colorabe item model ( not in the camera but in the item shower or how is it called) u right click on the model and select add ovverride materials and then right click again but choose show in element viewer ( is it called like this? dunn but i think u know what i mean) and then click on amterials and one of the buttons under it changes the color, that is how i change hair colors on a normal character, if it doesnt work try to look on youtube.
