Scingularity

The Asset Store's most realistic black hole shader.  
Inspired by the stunning visual effects of the film "Interstellar" and the game "Space Engine," this is a feature-rich black hole effect optimized for maximum performance while replicating a number of real physical effects:  
• Features gravitational lensing, red- / blue-shifting, and thermal coloring from blackbody radiation.  
• Renders in real time.  
• Can take into account custom skyboxes and objects in the scene, properly discriminating between objects behind and in front of the black hole.  
• Includes an optional built-in adjustable accretion disk.  
• Supports multiple black holes in a scene at once, with arbitrary rotations and scales, for exciting black hole collision simulations.  
• Can be easily repurposed for use as a wormhole or the gravitational lens effect of a distant galaxy cluster.
