Thank you for the response, much appreciated. I will go down this path and see where it leads and post my developments )

Hi, First post here and looking forward to learning more C4D from you guys.

I have a question in relation to the automatic triggering of a camera to record a scene.
To illustrate what I would like to achieve the picture below shows the path of an object. As it enters Cam 1 position within Circle distance, I would like it to add frames (footage) to the render list for the time it is in within the circle (distance from camera), as it moves to camera 2 it starts to record from that position and so on. If there are any ideas how this might be acheived in an automatic way...I would be eternally grateful, many thanks.
