V-Ray 3.52 for Maya
- Use a regular camera in Maya. Lens/FOV settings shouldn't matter because it is a "proper pano" in grabbing all 6 angles appropriately to later stitch together.
- Open the Attribute Editor for the camera, and make sure that the "Camera settings" and "Stereoscopic camera" menus are shown via the VRay submenu
- Scroll to the "Extra VRay Attributes" portion of the Attribute Editor and check "Override Global Camera Settings"
- Change the camera type to "Cube 6x1"
- Check the option to "Treat as VRay Stereoscopic camera" and the "Adjust Resolution" box in the "Stereoscopic camera" settings
- Open the Render Settings window and make sure that the "Render Using" option at the top is set to "V-Ray"
- In the "Common" tab, change the resolution setting to Custom, disable the option to maintain Width/Height Ratio, and set the pixel resolution to 9216 width by 1536 height (this gives us 6 1536x1536 cubes)
- You're all set to render your panorama! Upload the image to irisvr.com/panos. Full tutorial here.
