We are upgrading from Houdini 18.0 to 18.5 and when I open a scene that was working on 18.0 the camera view is all messed up. I figure that is because the aperture values were changed, seems I need a multiplier of 100 or so.

Anyways, if I drop down a camera node set to edit and click the "Initialize Parameters for Edit" button (love that btw!) I get a RuntimeError: Accessed invalid expired "Camera" prim <path>. The <path> however exists and is the valid path for the shot camera.

The camera node afterwards mostly works, but the aperture settings are disabled and cannot be edited (which is exactly what I need to edit however to get the correct view back). Similar to Tims problem here: https://www.sidefx.com/forum/topic/78049/ [www.sidefx.com]

Any ideas how to remedy that?
