So I made a blast beam turret for the Adamant. This is a test to show off the aiming and firing. It's very quickly put together, so it's not supposed to be professional, and there are currently no real details on the turret, but this gives you an idea, hopefully. =)
The laser beam itself is a simple 8 quads arrayed in radial fashion and given a stretch-to constraint, which is tied to a target empty which the turret also is constrained to.
The beam is given an emission material in Cycles and a beam texture with an alpha map to give it fall-off and then it's rendered. Voila, a laser beam cannon! =D
Hope you're all doing awesome!
