Title pretty much says it all. I’d like to have two cameras (i’ll be adding more) and it’s necessary they have different render sizes. I’m doing camera matching and when inserting a background image it is distorted unless the Render size matches the image. This is fine for the first camera, but when you create a second camera, insert the background image and adjust the render size it changes the size for both cameras. I realize this is desired in most cases but not mine.
You need to setup a new scene. Each scene can have its own render size settings.
Click the + next to the Scene box and choose Link Object Data.
Add a new camera, then delete the original camera. The original camera will still exist in your original scene, but now you can move the new camera about and most importantly set a new render size for the new scene.
