Pyramid Hologram is a demonstration, made for view 3d object in real illusion via pyramid structure of plastic or glass mirror effect.

Usage You can use a market pyramid hologram, or even DIY from tutorials.

How it works? Scene has cameras for object side watching, There is RenderTextures used to get camera side and use it anywhere, but we made a RawImage in Canvas with black background image to hide empty scene.

Why black background? Because for mirror illusion it is token as transparent.
