LUTBeams

Still fixing bugs and stuff ^^

Volumetric light beams for VRChat. As seen in Stage Flight and Furality.

Example uses:

1. Spotlights for light shows
2. Projector light for video players
3. Ambient light shafts

Installation

Either clone the whole project, or copy-paste Assets/LUTBeam/ into your project.

Usage

1. Place a LUTBeamManager prefab in the scene
2. Place a LUTBeamSimple prefab in the scene
3. ???

To change gobo (light cookie) images

Right click LUTBeamManager component and click "Generate Texture Array".

Notes

• Not reccomended for use on avatars, should work but may require some changes to be good.
• LUBeamManager is needed for a grab-pass to make the beam projection on surfaces look good.
• VRSL: Don't know but should be easy to integrate.

Tiles texture is from textures.com

Gobos textures are mostly by me, don't 100% remember.

How?

Raymarching volumetrics per pixel is way too expensive, I get around this by baking raymarch results to a lookup texture (LUT), so that they can later be grabbed very fast at runtime.

Somewhat similar to Latrix Laser System by OwenTheProgrammer, though theirs is far more advanced.
