Zero-Pass Workflow
If you are working solely with Fusion or Nuke, which accommodate overscan rendering, and use compatible lens models, you may be able to use a “zero-pass” (aka no-pass) workflow, where you don’t run the Lens Workflow script at all. That simplifies matters considerably, as there’s no need to run and un-run (undo) the lens workflow setup.
Instead, the distortion is exported directly from the solver to the downstream compositing app, and its 3-D renderer is caused to render “invisible” pixels off the edge of the normal image, where they can still be used by the lens distortion node in the compositor to be brought into the active image as needed.
The motivated user may be able to convince other apps such as Maya to also do the overscan rendering, storing the hidden pixels in EXR images, to be able to support the zero-pass workflow. If you have suitable expertise in that app and what information it is able to pull from FBX or USD files to support overscan rendering, and are able to do integration testing, contact us to see if we can add it into that exporter.
