VR Spherical Panorama Image Dimensions

[sidewalker]

I'm attempting to render a spherical panorama in top/bottom stereo at 6000px x 6000px. For some reason, the image width keeps getting reduced to 4854px after I click the render button. The image height remains set at 6000px. See attached screenshot.

Any explanation for why the image width is being reduced?

Hello sidewalker,

When the camera is set to VR Spherical Panorama, the Aspect Ratio of the resolution will have to be 2:1 and V-Ray will automatically re-adjust it to fit into that ratio.

To re-adjust the resolution, V-Ray is taking the height and multiplying it by two. In your case however there seem to be a discrepancy. Are you able to reproduce the same result in a new scene and if you are, please describe it in more detail, so we can reproduce and inspect it. It would be exceptionally helpful if you can provide us with the preset file of your render settings by sending it to support@chaosgroup.com

Note: To save your render settings file, use the "Save" icon in the bottom left corner of the V-Ray Asset Editor > Render Settings window. The file will be saved in a .vropt format.

After some trial and error, I believe I've found the problem. It seems the render output settings for the STANDARD camera (set to Match Viewport) were actually affecting the render output settings for the SPHERICAL camera. The spherical settings were being adjusted to match the viewport aspect ratio, therefore overriding the correct 2:1 aspect ratio. After setting the STANDARD camera to a 2:1 aspect ratio, the SPHERICAL camera now renders correctly. Strange!
