I have two bug reports
1. region render does not render region but whole image.
2. Octane has an issue with getting the P_FOCAL_LENGTH pin value from an alembic camera.
We use a scripted graph to get all needed camera info from the alembic camera and plug them into a thinLensCamera node so we can adjust other parameters still.
Up to and including octane 2020.2.1 this works perfect, but in 2020.2.3 the focal length does not seem to get updated when skipping through the timeline.
Attached is an example orbx to showcase the issue. The scripted graph code can be read by opening the orbx in a text editor.
