Hi TJPaul,
This sounds like an easy to answer question, and a decade ago it would have been. Since a while, Cinema4D requires to work on all levels properly using a particular scale. It goes these days even further with over a dozen 3rd party renders, whereby each of these might show at one point an individual behavior based on specific settings. Most answers that were given during the time where a “Unit-is-a-Unit” have only limited relevance these days.
Example: the camera icon size is dependent on the scale that you have had set up in the Attribute Manager>Mode> Project> Project Settings: Scale Project. Any conversion of the scale based on this with result in a change of the Icon. However, it also changes the Depth of Field results during rendering and other parameters. If the Project settings are done from the start properly, then all will be fine. Again, I can’t tell if there is any 3rd party renderer who might not like it, but I could find anything there off, so I’m perhaps just cautious here. What is a good scale? For me, it is always when the main objects can be defined with the first three digits left from the decimal point, which requires to think in meter, cm, or mm, etc.
Typically all should be fine while setting the camera scale to S.X, S.Y, S.Z to 0.1, preferable before animation. Select the Position and Rotation parameters, then right mouse click one of these and Animation>Add Keyframe selection, to avoid that the scale is accidentally changed while setting keyframes. It should be all fine with this, but as I mentioned, I can’t tell if there is a problem somewhere ‘down the road’.
I hope that helps
Cheers
