sorry to bump this thread, but it's VERY relevant to my problem. I'm trying to make the Baneblade autocannon actually fire coaxially to the main gun, instead of firing from no specific location on the Baneblade at random targets. So far, I've tried:
-sticking the animations, muzzle, and origin of the battlecannon into the empty fields of the autocannon's hardpoint_08. This makes the autocannon and the main gun aim by using the main turret, but when they're firing at different targets, the turret flickers back and forth between aiming at the two respective targets.
-creating an Obliterator-style weapon. This means that only one weapon can fire at the same time. I'd be fine with this, but both weapons use the main gun animation, muzzle flash, explosion effects, and sound. Everytime the autocannon fires, HUGE EXPLOSION.
