Object tracking using the Channel Follower Modifier
A simple and convenient way to make an object track or target another object, which gives more dexterity than the "target" option in the motion control panel, is to use the Channel Follower modifier to link the rotational path of the observing object to the motion path of the target object
First Open up the Channel Follower modifier

Linking Channel Follower Modifier to target
Next, link the pitch rotational movment of your turret to the target's Y position
You will need to adjust the proportional scale of the tracking movment, and then might require trial and error. Usually larger numbers, 1,000% and greater are required.
For tracking the pitch against the Y axis position, you will need to multiple the scale by a negative, otherwise the turret's pitch will be opposite.
Repeat for the Turret Objects Heading and use trial and error to get the correct scale. The heading will not require a negative.
The final video will look something like this. |
