SYMPTOM

Rendering frame does not appear in the 3D Viewport when the Active Camera has a custom rendering resolution, despite the mesh icon being correctly parented to the camera.

ISSUE

I believe the issue being that the Frame Mesh was initially created in a collection that is currently hidden in viewport, while the Active Camera is in another visible collection.

SUGGESTED SOLUTION

Since a mesh can be a member of multiple collections, maybe ensuring that the Frame Mesh is only found in the collection containing the Active Camera will solve the issue?

In short: Move Render Frame to the collection used by the active camera.

Hi,Gatada，
two bugs I found in jb-multicamera.py
the previous version did not have this error.
the new version of your multi resolution camera addon cause Blender unable to hide objects, neither use shotcut nor clicking the eye icon in the outline panel.
another one is the checkbox “highlight selects Camera” ，turn it on will make Blender freezes,
tested it in Blender2.41 and Blender2.61LTS ,without any other addons,

My script is simply:

import bpy

bpy.ops.wm.open_mainfile(filepath="blenderfile.blend")
save_path = "/tmp"
room_name = "room01"

for i in range(bpy.data.scenes["Scene"].frame_start, bpy.data.scenes["Scene"].frame_end+1, bpy.data.scenes["Scene"].frame_step):
    bpy.context.scene.frame_set(i)
    camera = bpy.data.scenes["Scene"].camera
    file_name = "%s/%s-%02d" % (save_path, room_name, i)

    print("Rendering Frame:", i, "on camera:", camera.name)
    bpy.ops.render.render_still_with_custom_resolution(camera_name=camera.name)

Running it with: Blender --python script.py -b

Results in the the first Frame rendering then crashing at the end with:
