View Full Version : why use a null as a camera controller?

06 June 2010, 07:02 PM

i often see people making a 3d null object, while working in a sequence which involves a 3d space, and parent their camera to that null.

now - what is the reason they do that instead of using the camera itself?

plus, where can i read about the differences between all of the cameras? (35mm, 50mm, etc..)

so that you can control the camera in view, with the move arrows of the null object.

Ok.. Is that the only reason?

the other reason is that it gives you another pivot for offset animations. so you can animate the null then if u need to pull the camera back while maintaining the same general animation you can add animation to the camera while leaving the null as is. its very flexible

i think of it as an old fashioned way of animation layers. i use this technique all the time in maya for camera and find it more immediate than using animation layers

It's also pretty handy for focusing on layers in 3d space. You can send the null object to the position of the 3d layer, and then rotate the camera around it freely. Video Copilots Sure Target plugin is great for this, and uses a Null>Camera setup for it.
