Black hole shader, simple to use, has a light and realistic version, each of which has two design options. Works in 2D and 3D, with perspective and orthographic camera.

Works on PC, mobile devices and VR.

Allows you to control:

1. Select a view with or without halo
2. Select the mode for orthographic or perspective cameras 
3. Width of all parts excluding singularity
4. Halo color
5. Color of the photon sphere
6. Width of the fluctuating part of the accretion disk
7. Width of the non-fluctuating part of the accretion disk
8. Width of the fluctuating part of the accretion disk
9. The speed of light oscillation in the fluctuating part of the accretion disk
10. Ligth brightness
11. The noise used to generate oscillating light
12. The degree of light deflection during gravitational lensing
13. Smoothing light deflection in gravitational lensing (scale of deflection of all rays)
14. Enable or disable smooth transitions between reflection probes in a realistic version of the shader
