so if there is no way to guess (or change attributes) so that the viewport will match what you need in the poser window, with a scaled camera...why did you guys included the "include scaled cameras" in the first place?
some shots are just close to impossible using a 100% scaled camera (I can give tons of examples), so your only choices are either scaling down the camera, or scaling up the entire scene (which can be quite tedious...).
I think that if I knew how much exactly the engine "fakes" it would help a lot. lets say I placed the camera on 10XYZ, and I knew where octane places it, I could tweak the numbers in poser AFTER placing my camera where i need it, and than get the desired shot within viewport.
