Copy of distinct camera parameters ??

AndyS

Hi,

how to?
I want to paste only some parameters of one camera (i.e. focal length, focal distance, F/Stop, etc.) to another camera without changing the general parameters (translation, rotation, etc.) of the second camera.

What ever I try, the copy - paste (selected items) ever changes all parameters of the second camera, too.

The only way I can think of doing it for copy and paste is to lock the properties you want to remain unchanged. Another option might be to save a Properties preset (though I've not tried douing that for a camera) and be selective about what was included.

You could save a pose preset for the position and rotations, use the copy/paste or duplicate the camera then reload position and rot from the pose preset.

In the future, if you want to do this with a little more ease...

Place your camera in a group, by itself, and move the group, not the camera. You will still be bound to copying all the other settings, except rotations and translations, which should all be 0 in the camera you are copying from. I use this, like a "dolly", so I can attach lighting to the camera too, as well as adjust the camera-heights to specific eye-levels, without altering the positioning on the "floor". (Since the group axis is set to the floor and I raise the camera within the group. However, you will be doing the opposite. You want to move the group to simulate moving and rotating the camera, without actually moving or rotating the camera's movement values.) Just be sure to ALSO lock the XYZ rotate/translate/scale for the camera, so you don't accidently move it, when you are viewing through the eyes of the camera itself, in the display. You have to use the groups dials to do that.

Hope that is a decent workaround.

The only other solution is manual copy and paste of each individual value. However, you may try duplicating the camera and then "paste pose to selected item". (Use another camera that you setup the "pose" for... Then you are just moving that duplicate camera to the other cameras position, which includes rotations and tranlations and scale, I believe.)

Depending on your specific use, you may also try locking your focus to a target, or "look at". If this is simply a matter of wanting a second camera position. (Where, obvioulsy you will not have the same rotations and translations, but all other values will be the same. I am just not sure if this is your desire for the camera. You can use a look-at target which is a null-node, or a part of the model, like the face/eye/leg, etc... I don't think you can target a blank group.)
