I had to edit the starting position (MOVE IN BLACK) pan to go around past 360 (DMX value 192) then the Move to (DMX value 149) doesn’t cause the head to spin around backwards.

The second effect, slightly later on the timeline (e.g., a second later), pans to the left 45 degrees. Finale animates the beam moving from 45R to 45L.
It is important that we are using the term “pan” to mean the same thing.
In Finale’s coordinate system, “Pan” is a right handed rotation around the Y (up) axis. If the beam is aiming straight up into the sky, then “pan” would not make any perceivable difference because pan would just be rotating the beam around its axis, still aiming straight up in the sky. Let’s assume that what you want is the beam to be aiming 45 degrees to the right in the ground plane (horizontally), and to sweep within the ground plane to 45 degrees to the left. In the middle of this sweep, the beam would be aiming straight out at viewer. (By contrast, if you were “tilting” 45R to 45L, then the middle of the sweep would be aiming up into the sky.)
Getting the beam to aim 45R in the ground plane requires both “pan” and “tilt”. Tilt in Finale is the right handed rotation around the X-axis that points to the right from the viewer’s point of view. So tilting the beam 90 degrees aims it straight at the viewer’s face, which is where it is supposed to be in the middle of this pan-sweep from right to left.
Using both “pan” and “tilt”, the Move-in-black effect that begins the sweep should have:
tilt = 90
pan = 45
The Move-to effect that ends the sweep should have:
tilt = 90
pan = -45
The animation of the beam should look correct in the 3D view, and Finale should export the correct values in the script for the fixture. Below is an example exported script for Cobra using a TomShine 80W moving head fixture. The “tilt” value is 28 for the full sweep, because tilt doesn’t change. The “pan” value goes from 21 initially to 149 at the end of the sweep. This looks correct to me.

END,,,,,,,,,,If you are getting a different result, then can you create a test show with just two effects (the move-in-black and move-to) to illustrate the problem? Please send the test show to will@finale3d.com, and I’ll answer here on the forums after figuring out the issue.

I deviated slightly by only tilting to 55 degrees instead of 90, but the rest appears identical.
The sweep looks correct in F3D. But in practice, the RED move-to goes the opposite direction expected – pointing the beam backwards (to the audience(.
This is the script it generated:

This is how I manually fixed the issue by editing the script directly. On the move-in-black I started at 192 (which is effectively 406 degrees or once around plus 45 degrees).
Then the red Move-to goes “down” to 149 (from 192, which is about a 90 degree arc).

END,,,,,,,,,,Looking from top down on the fixture, it spins 405 degrees (counter clockwise) for the “Move-in-Black”. Then the “Red Move-To” pans 90 degrees from Right to Left.
This gives me the effect I’m looking for…
