What camera does 3dmax use to render a 360 panorama?

3dmax uses a common camera to render a 360 panorama. You need to set the panoramic range angle in the camera settings of the VRAY panel, open your finished scene in 3Dmax, then create a camera in the scene, which can be a target camera or a free camera, and then adjust the viewing angle.

Making method of 3dmax rendering 360 panorama camera.

Create a free camera and place it in a suitable position in the scene. Move the camera to the middle of the space we want to render. A camera is like a human eye. Where to put it is equivalent to a person standing in that position to see things. Set the aspect ratio of 2 to 1 in the rendering settings, because the aspect ratio of 360 panorama must be 2 to 1, otherwise there will be no 360 panorama effect.

Then select the camera type as spherical, check the coverage FOV and adjust the coverage FOV to 360. After the adjustment is completed, click Render, and click Render to directly output a 360-degree panorama. The rendered panorama is generally distorted like this.
