Adding a “dolly” function to a camera rig
I am putting together a simple camera controller. I have no problem as far as orbiting the camera with expression controls and following a controller null around. However…
On a couple of the plug-ins I’ve seen, there is also the option to “track in” on the control null. That is, not just move the null and also the camera, but adjust a slider to move the camera toward and away from the the control null itself.
My expression writing skills are fairly basic. Can someone give me a tip on how this is done, or point me toward someone who has explained it?
Sorry, there were no replies found.
