Fewes / vr_extended.shader

Last active January 9, 2019 23:34

A modified version of Valve's standard shader for The Lab renderer. It supports vertex colors, vertex AO (alpha channel) as well as up to four detail textures. It also repacks metalness, roughness, AO and the detail mask into a single mask texture. Please note you need the custom GUI for it: https://gist.github.com/Fewes/43f2b97fe8785e9a69e22836…

	// Modified to support vertex colors, vertex color linearization, vertex ao (through vertex alpha), up to 4 detail textures as well as tighter mask packing
	//
	// The mask texture is laid out like this:
	// R - Metalness
	// G - Roughness
	// B - Ambient occlusion
	// A - Detail mask, where:
	// 0-25% intensity = Detail map 1
	// 25-50% intensity = Detail map 2

Fewes / ScrollableEditorCameraSpeed.cs

Last active April 11, 2017 17:00

Allows you to control the scene camera speed using the scroll wheel in the Unity editor (much like UE4).

	using UnityEngine;
	using UnityEditor;
	using System.Reflection;

	[InitializeOnLoad]
	public static class ScrollableEditorCameraSpeed
	{
	static ScrollableEditorCameraSpeed()
	{

Fewes / Distortion.shader

Distortion shader for Unity. Supports a normal map.

	Shader "Distortion"
	{
	Properties
	{
	_Refraction ("Refraction", Range (0.00, 10.0)) = 1.0
	_Power ("Power", Range (1.00, 10.0)) = 1.0
	_AlphaPower ("Vertex Alpha Power", Range (1.00, 10.0)) = 1.0

Fewes / PixelDot.shader

Last active May 12, 2021 04:38

Renders a screen-aligned, distance-independent, resolution-independent, pixel-perfect quad in Unity. Use it with the built-in quad mesh. You don't have to rotate or scale the mesh renderer, the shader will take care of it.

	Shader "FX/PixelDot"
	{
	Properties
	{
	[NoScaleOffset] _MainTex ("Texture", 2D) = "white" {}
	_Color ("Color", Color) = (1, 1, 1, 1)
	_Size ("Pixel Size", Range(1, 64)) = 1
	}
	SubShader
	{
