Exclude fixtures from shape movement

[acetaxidriver]

Hi.

I have 8 fixtures with pan/tilt movement, but at some time I want stop 4 of them in a fixed position, getting 4 moving and 4 fixed.
I have a playback with the 4 fixed fixtures using a position palette.
How do I stop (and later resume movement) those 4 fixtures?

Thanks
AC

In Titan you can use block shapes for this.

That will do the trick, and with playback priority can assure whatever pan/tilt playback is applied it still be fixed.

Thanks
