heres a final visual test but with default spars and those bullet holes...

...waiting an overlay of damaged fabric on pending wing frame damage.
note the lower wing is showing instead inner canvas because theres not enough pcx space to do both sides, never was! so i sacrificed the bottom side for full upper damage and in this arrangement no need for transparency. otherwise the original partial damage elements for both sides were an eyesore to mesh with the undamage elements anyway, plus it'll double as the same full damage seen from cockpit view - cheers
