The exporter is written for v2.2b - I've not tested it with v2.3.
Are there changes to the way the camera works in the this new alpha/beta version ?
The origin in the SKP is very near the center of the view so I don't see what's up with the OCS camera ?
In v2.2b moving the camera does have quite rapid jumps because the model is quite small, however if you rest the camera if centers on the correct 'origin' and you can retry pan/zooms...
If you save/close the OCS with a changed camera, and then re-export the SKP WITHOUT ticking the 'camera export' settings then the last OCS camera is used when the new export opens it...
I copy/paste from the help PDF...
Navigating the Scene
Octane Render provides a refreshing and exciting rendering experience due to the ability to
interact with the scene with final render settings. This interactivity allows for renders that
might not be possible with traditional render engines. The user can continue to hunt for that
perfect camera angle where all the reflections of the lights are just right or they can continue
to adjust the DOF in real-time.
The Render Viewport can be manipulated like traditional 3D viewports with rotation, panning
and zooming controls.
Navigating in the Render Viewport (While holding your mouse over the Render Viewport):
Rotate: Left Mouse Button
Zoom: Mouse Wheel / Middle Mouse Button
Pan: Right Mouse
If the scene navigation is too slow, hold the SHIFT key while navigating with the mouse.
You can also manually adjust things like the Camera's "target" in the OCS panel's camera settings...
