I've got another idea.... again...
First off, question. the lastest pcs 1 build that supports gun normals, I can't get the pcs view window to have the normals actually move, their always pointing (0,0,1) even if i change the values. Is this normal?
Now the idea... Allow you create a dummy object (call it target point), a box will do, allow you to move it around, closer or further away from the model. Select a gun or guns, and have them autovector to that target. This will allow you to quickly setup auto convergence.
Heres a pic (Black is the ship, blue is the dummy target, green is the gun barrels, red are the vectored lines)
