RenderTexture.ConvertToEquirect

Parameters

Description

Converts the render texture to equirectangular format (both stereoscopic or monoscopic equirect). The left eye will occupy the top half and the right eye will occupy the bottom. The monoscopic version will occupy the whole texture. Texture dimension must be of type TextureDimension.Cube.

        //assume cubemap and cubemap2 are rendered using Camera.RenderToCubemap() for left/right eyes
