Does anyone know of a plugin that can remove backface materials from a selection... I just need to work on a specific selection.
Dezmo_remove_back_materials.rbz
Here are a quick one...This will remove Back Face Material from selection recursively. You can undo it.
Start by toolbar icon or context menu after selection.
The result will be printed out to Ruby Console e.g.:
"Back Face Material removed from 11 faces."
or
"Back Face Material removed from 0 face."
Quickly tested only on Windows. No responsibility... but should be okay on MAC too.
(Sorry about the ugly icon 
)

@count = 0
remove_back_materials_recursively
plural = @count > 1 ? "s" ; ""
p "Back Face Material removed from #{@count} face#{plural}."
model.commit_operation
