What is "Revert Baking" used for?

In what circumstances would one use this option in the new Baking feature?

Sorry, that reference wasn't clear to me, I still don't understand

You can create custom camera lenses and shapes with geometry.

For example, make a sphere, and instead of baking the sphere's surface (default), this flag will turn it into a spherical shaped camera - like the built in panorama projections. You can take this further using any mesh shape in place of the sphere to define your own types of panoramic camera projections.

I'm the guy in the tweet above. I'll be testing this as soon as I'm back at work. We're hopeful that it'll solve an issue for us, will report back.

So I have a scene I'm playing with this on. I've added a baking camera, ticked "revert baking," assigned a new baking ID to the mesh I want to use, and connected the baking camera to render target. Getting all black output, so am quite sure I'm doing something drastically wrong.
Continuing to play with it.

If anyone has a working demo file they want to share, i'd find it useful.

Just to confirm are you using the mesh as a camera volume? Could you share a screenshot of what it looks like when the baking is not flipped? Also, an ORBX package if you can may help.

Coming back to revisit this topic. I don't have something working right now to post, but have been able to get baked output from individual meshes, but not using a mesh "lens" for the scene as described above. I think I just don't understand how to set it up, or am missing something fundamental about what's expected.
My original post on twitter had been about wanting a true "fisheye" camera for Octane, i.e. similar to what VRay's "VrayCameraDome" output looks like - a perfect 180 degree fisheye render, which for our purposes is precisely what we need. So that's what I'm trying to set up. If anyone is fiddling with reverse baking and has anything I can look at, I'd appreciate it.

Hi guys,

I'm posting a sample scene setup using a hemisphere geometry to render a fisheye camera using the baking camera functionality and the "Revert baking" option.

I hope it helps

VERY much appreciated. Thanks for posting.
