60%+ of the latlong format renders floor and ceiling, which are the rarest looked at and take up most of the image.
Converting to Cubemaps via converter is an option, but sampling the ceiling and floor so much only to crush it away in a converter is painful.

Cubemaps became a standard now for VR.

Just a note: this was requested many times, also in our support portal. So I guess we should at least consider adding this feature at some point.

What am I missing here? Is this about those 6 images stitched together (while there are enough different conventions to do so to get crazy)?

This?

What would be the difference to placing some animated camera and render out 6 frames (+ stitch if necessary)? Or is this about comfort only? Or a special handling of UHD cache to avoid seams?

Just curious,
Good Luck

Never underestimate the power of a well placed level one spell.

I forum searched a request post, maybe I missed it.

Basically you got it all right.
90° Stereocube maps with Proper implementation for eye distance, the 8cm neck offset, eye conversion distance... Etc.
Sure you can do camera rotation via script, but you lack the control you are used to otherwise.
UHD is the smallest of problems... Denoise will create major seams, no matter how well or clean it is handled.

May I have a possibly stupid question? According to this: https://coronarenderer.freshdesk.com/support/solutions/articles/12000012853-cubemap-camera-is-designed-for-images-with-aspect-ratio-6x1-12x1-in-case-of-vr-camera-different-as
 the cubemaps are in deed implemented - but I cant find a way how to enable this feature in corona - is it only in the daily build?
