Neitri-Unity-Shaders

Collection of shaders for Unity3D and VRChat. World Normal and World Positon shaders have been used as basis for more interesting advanced effects, such as:

• triplanar decals
• color wave
• distortion wave
• cover everything in texture

Simple shaders

Types

• Shader marked with 🚪 render what is behind them with some effect, they don't go on your avatar but ideally on some "window" that you will look thru. Post processing might ruin results of these shaders.

• Shader marked with 💡 need _CameraDepthTexture, to ensure _CameraDepthTexture is enabled please add a directional Light anywhere to your avatar (idally enabled only when the "window" is enabled) and set it's properties in the following way:
  
  The settings above should be optimized enough to not cause any additional render passes, if they do, the render passes should be low resolution. Intensity value has to be over 0, because if it's 0 Unity considers the light as disabled. You need to do this because Unity's forward rendering _CameraDepthTexture is enabled only if world has at least one light with shadows enabled or if game maker sets Camera.main.depthTextureMode = DepthTextureMode.Depth. Shaders that use depth texture will be more imprecise or noisy the further you are from position 0,0,0. That is due to the nature of floating point numbers, it's a Unity thing.

Censor 🚪

Both VR and non VR see same censor squares.
Censor square size decreases as distance to it increases.

Clispace Raymarching 🚪

Example on how to construct world space ray from clispace uv. Useful as start for fully raymarched worlds.

Wireframe Overlay 🚪💡

Overlays background color on top of original scene.

Wireframe Fade 🚪💡

Fades into original scene color.

World Normal Nice Slow 🚪💡

Slow because it uses two passes instead of one.

World Normal Ugly Fast 🚪💡

Fast because it uses one pass, ugly because it uses ddx and ddy which work in 2x2 blocks.

World Position 🚪💡

World Cutout Sphere 🚪💡

Efficient single pass world cutout shader. Uses ray sphere intersection, so works only as spherical cutout.

Distance Fade Outline 💡

Fades outline (aka rim lighting) based on how far it is behind objects and how far it is from camera. Add it to bottom of material list in Renderer component, so whole object is rendered again with this material. Used in migero's Foosball 1vs1 Or 2vs2

Prefabs/Worlds

Complex combination of shaders and specifc mesh/component/camera. Contains premade prefabs or example worlds.

Depth Mirror

GPU Particles

Example World

Grafitti Wall

Neitri Clock

Most up to date versions of my clock. Also distributed thru VRCMods

Shader Debug

Prefab that helps with world light debugging. I use it to debug issues with my Neitri MMD shader.

Wireframe Projector

Wireframe Projector Prefab inspired by the one found Avatar Testing‼ by Mimi's
