Render 360 VR

[technique]

Hello I would like to know how to render 360 Vr with Vray 3.40.06 and Maya 2017 correctly.
I explain my camera correctly with a "Camera Physical" and then I add a "camera setings" attribute with a 360 FOV and a spherical type.
Until then everything goes well but when I open the image in eg gopro Player, the picture that appears does not match the framing of my camera in the Mayan viewport.
It's a shame because it becomes complicated to adjust the framing of the camera, otherwise everything else works well.

Thank you for your help.

Can you share a viewport screenshot and point out what doesn't match?
For VR you would usually want to render in stereo - just add vray stereoscopic attributes to your camera. Then in the camera settings attribute choose either "spherical panorama" or "cube6x1" - depending on your VR set.

I see what you mean.
Well, here's the thing with 360 images. When you render the image, a 360 degree sphere is constructed around your camera (in actual fact, the image is projected onto a sphere around your camera, but that's not important now). Having this in mind, the position of your camera in your scene will determine the center point of your 360 image in your 360 viewer. In your case - if you want your motorbike to be the exact center of your image, you need to place your camera where your bike is (although in this way, from the VR player you'll be able to see "around" the bike - as if you are standing on it - you won't be able to walk around it). Maybe you can try that or try placing the camera right in front of the bike.
You need to more or less ignore what the viewport displays, it won't show you what your VR player will show you, and the reason is again the way the image is projected around/from your camera. The viewport gives you a perspective view, while your 360 player gives you a spherical view.

When it comes to settings, I'd recommend switching the camera type to "spherical panorama" instead of spherical and then setting FOV=360 and vertical FOV=180 (at least that's what most players require). Although, the goPro player seems to handle quite well whatever is passed to it. Another recommendation would be to render in 2:1 ratio, i.e. 2048x1024 or higher.

I strongly recommend taking a look at our guide to VR - it has most of these details explained: https://labs.chaosgroup.com/index.ph...ual-reality-2/

There is no solution to have a return of the projected image in the viewport which facilitates the framing of the camera for work in animation 360.

Unfortunately no, there's no such way for the moment.

yeah, it's not a vray thing, it's a 360 VR thing. The only thing that matters is the position of the camera. Move it closer to solve your problem. You can set the focal length of your maya camera to around 5 degrees that will make it look super funny in the viewport, but it will give you a better idea of where the object in front of your camera will end up.

If you were to view that in a real VR headset with a 110 degree FOV, then the bike would appear much closer. A VR player is not an accurate representation of what you will get.
