Hello guys. this section is not updated for about 7 or 8 years but some of this solutions can still be helpful for someone.

Sprite RGB+A ETC1

IN: Image(RGB) + Image (A)

OUT: Sprite

USAGE: Use an ETC1(RGB) image along a grayscale (Alpha8) to create a sprite. 

COMMENT: Sprite solution for old devices without ETC2, ASTC or similar format. Useful if your target includes Mali-400 or similar Low-end GPU (Ex: Low-end SmartTV, Low-end androids...)

Sprite RGB+RGB ETC1

IN: Image(RGB) + Image (RGB)

OUT: Sprite

USAGE: Use an ETC1(RGB) image along another ETC1 (R - Alpha) to create a sprite. 

COMMENT: Sprite solution for old devices without ETC2, ASTC or similar format. Useful if your target includes Mali-400 or similar Low-end GPU (Ex: Low-end SmartTV, Low-end androids...). Less space usage than an Alpha8 but there's two unused channels (Maybe you can figure out some cool stuff to do with that).

Unlit Equirectangular Stereoscopic Background

IN: Equirectangular Image(RGB), Rotation, Expose, Stereo type (none, Top-Bottom, Left-Right)

OUT: Two Textured Spheres

USAGE: Create two materials and put it into two different Spheres into two different Layers. Create two cameras with the same transformation, setup one to the right eye and the another to the left eye. Change camera's culling property in a way that only one sphere is rendered on each eye. (You can also use it on monoscopic images/video, in that case, just ignore all left-right explanation and choose none on stereo type)

COMMENT: Good to create a stereoscopic video player.

Unlit Cubic Stereoscopic Background

IN: Cubemap(RGB), Rotation, Expose, Stereo type (none, Top-Bottom, Left-Right)

OUT: Two Textured cubes

USAGE: Create two materials and put it into two different cubes into two different Layers. Create two cameras with the same transformation, setup one to the right eye and the another to the left eye. Change camera's culling property in a way that only one cube is rendered on each eye. (You can also use it on monoscopic images/video, in that case, just ignore all left-right explanation and choose none on stereo type)

COMMENT: Good to create stereoscopic experiences based on cubemap. (Cubemap can be created from several formats including the famous +X-X+Y-Y+Z-Z format. (Compatible with HDR)
