So long as they're in a "turret" type slot, yeah. Turrets render above hardpoints, and within each type, larger weapons render later.
Please dont take it, like I want to stubornly go against "rules" at all costs, its a.. visual matter really. But basicly what I would like is to get two, what an outsider viewer would see as
"two pipes" above a rocket pod. Now.. what I thought to do was somewhere in the lines..
1) make a sprite as usual
2) the missile pad (which would be a hardpoint)
3) on top of that place a "decorative" weapon - turret, as I believe you would advice, which would merely be those two pipes and with 0° arc it would stick
in position. (and be above the missile pod)
So.. in hull codex you would see a ship, without any "weird extra stuff".. and in variant codex - the real stuff. If composed on top of each other correctly and precisly,
the result would be a "fake" perspective, as the pod in below the pipes (in my case at lower part of the frigate).
Basicly..just help the current system with a "fake" ship part, which is small, so in battle it shouldnt be noticable.
Would that work?
