Then the gun gas purge door automatically opens and closes during firing of the gun or whenever the pilot selects/deselects gun mode (in flight only?)? If so, it would be nice to have this door animation too (along with streaming gun gas exhaust from the opening). For ramp start, that door can be in open position upon entering the 3d world than auto close at some point after engine start. Can that door be manually reopened after hydrolics have pressurized?
It opens when gun is fired.
And unless you’re capable of exerting more force than an aircraft’s hydraulic system, you’re not opening that door after start. Remember I said the pin is inserted from the inside out for a cold gun? Now imagine the gun is hot, and you realise the pin is inserted the wrong way at EOR.
