Hello Corona folks / development team :)

Can a fish-eye lens be added to Corona's camera? I do planetarium work for NASA and would love to be able to use Corona for all of the work we are doing. Unfortunately the final format has to be a 180 degree fish-eye render.

The only engines I can use for this correctly in C4D are Arnold, Redshift, Vray.

I would absolutely love to use Corona on these projects.

Attached are a couple images for reference of what I need to be able to achieve.

Thanks so much!!

Any word on this from the developers?? Most other engines have these camera options... Arnold, Redshift, Vray, Cycles... Just would really love to get an eta on when something like this can be added.

Thanks guys!!

Wait... Corona doesn't have fisheye? That seems crazy!?

Okay I would like to personally pay Corona team the sum of $2,000 to add a fisheye lens feature in the next two weeks. C4D version please.

Please let me know if this is possible ;))))

If you're so desperate to get fisheye from Corona, then you should know that there already exists some workaround. You just need to render from camera with spherical projection, load that image into any app that is capable to perform projection transformations (ptgui, hugin and many others) and transform from equirectangular to fisheye. It's not very convenient, it requires more resources to render, but at least it works. And it also has a nice bonus - you only have to set up position of the camera in 3d app, but you are free to choose any rotation that you want in post.

Having said that, here's my +1 for fisheye projection in Corona :]
I'm not Corona Team member. Everything i say, is my personal opinion only.

Thanks for the response. I know this can be done I'm just hoping for a production ready fisheye camera within Corona to use it for feature length documentaries.

I have set this conversation up in Fusion and it works great. Just not production friendly. Also these films are rendered in 4K. If I us Coronas spherical camera I would have to render at 8K x 4K!

Just hoping for the real thing soon...

Thanks for helping though! - Shawn

You can also try the good old CG trick: create a perfect mirror sphere and render from that sphere (ie. camera targeting the mirror sphere). Your scene will render mirrored and you'll lose pass compositing but that's better than nothing.

Nothing yet - it would pop up on here https://trello.com/b/EfPE4kPx/corona-road-map-3ds-max (since it would be a core change I believe)

Here I believe the C4D team wants to take on the responsibility of implementing it, because of you ;)

Awesome! Yeah I know they've mentioned it and I'm stoked it's possible to implement!

I guess I'm waiting patiently... Please let me know if I can do any testing of any developer builds.
