Thanks very much for the responses.
I was referring to the constant nature of the speed of motion and camera rotation. Sketchup starts its motion and camera rotation at full speed and ends at full speed. You are correct that the camera translation is not in a straight path. I assume this is what you mean by roll.
My example of sketchup was only for clarification but it apparently failed miserably My goal is to match the motion I was getting before with Enscape. I cannot achieve that with the current camera system. Before motion and camera rotation were constant and now they are not. I have developed production workflows that depend on the type of motion Enscape was using before. Is there any way I can match the old motion between two points?
If you need me to produce an example using both I can, but currently I am slammed so it will take me some time. It also requires me installing 2 different versions of enscape which I am hesitant to do while in the middle of production. I am sticking with the old version for now.
There are many applications for this functionality. The one I am using it for currently is to add animated objects to an environment created in Enscape.
