Rendering a panorama

- [Instructor] Arnold makes it very easy to render out…panoramas of various types, and we have options for…anything from a single cylindrical or spherical environment…up to and including…full-motion stereoscopic 360 degree video.…In this example,…we'll just create a simple spherical environment map.…There are two requirements for a spherical environment,…or equirectangular projection.…If we want it to work properly in a viewer,…or a map properly, as a HDR image or background,…then we need to have a level horizon line.…

Select the camera in any viewport,…and in the channel box we see that…the camera's Rotate Z attribute is zero,…and that's the rotation around the camera's line of sight,…or it's canted angle or Dutch tilt.…We want the horizon line to be level,…so Rotate Z should be zero.…Also notice that the X rotation value is zero.…That's the tilt rotation for the camera,…and it's important that it also has a value of zero.…

Otherwise you'll get a weird wavy horizon line…in your spherical panorama.…Then when the rendering is loaded into a panorama viewer,…
