Camera travels along a twisty spline through a tunnel that is a sweep of that same spline. On either side of tunnel are tracks which are swept from array of smaller objects offset from same spline.
In front of, and offset from the camera along the same spline is some text which has target tag applied so it always correctly orients to the camera despite constant rotations.
I want the tracks on the sides to maintain that orientation too (always hard left and right from camera perspective.) In other words, imagine the tunnel is a hallway, and there’s a hand rail on either side. The hand rail doesn’t do you much good on the floor or ceiling, so I’m trying to keep the rails hard left and right.
I’m not sure why it’s not just automatically aligned. after all, I’m not telling the camera to turn. It’s just following the spline. Since array is just following the same spline, I would think it’s rotation would match, but apparently not. Anyway, I’ve tried several approaches using target to cam, and can’t get it working.
EDIT: It appears that the mismatch in twist between camera and tracks may be due to the fact that the camera is following the spline directly whereas the tracks are a swept rectangle which is THEN put into an array. I think doing the array after the sweep is causing the additional twists and some other issues.
I can’t seem to get it to sweep an array. It always sweeps only 1 of the rectangles, and leaves the other. Trying for past hour to look up a way to do this, but so far no go.
