Corona and virtual reality content

Hi everyone!
I've just tried to render stereoscopic 3d in corona. I was able to get a spherical image 2:1 ratio at 2048px (so left+right gives me a 2048x2048 image)
It works fine in my samsung gear vr, but theres a slight distortion near the poles. I did not get this problem with v-ray, since it renders a 12x1 cubestrip with resolution 1536x18432px
Can I just increase the resolution when rendering a spherical projection in corona, or is there a way to render a cubemap instead?
(Somehow I get the impresion that gear vr requires spherical panos to be at 2048px, just as it requires the cubestrips to be exactly 1536px height or else gear vr will display visible seams at the edges of each cubeface)
Kind regards

Update: OK, I just tried to increase resolution to 4096x4096. Works like a charm in samsung gear vr. Still a slight visible distortion at the top pole, but nothing I can't live with. I love the fact that i can save and view a preview after only 5 minutes of rendering :-)

Hi. I've too have seen this distortion at the poles. I found out that if "eyes front" (second parameter - can't remember the exact name) is set to 0 then the distortion goes away. I also found that 4048 x 4048 is the smallest usable resolution.
