Simple Custom Shaders

Simple Custom Shaders

A few simple custom post process shaders I added to the game for fun now that they can be uploaded to the workshop. You can find all of them in Post Process > Effects. All of them can be configured if you click on the icons.

Some of these shaders are CC0/MIT licensed shaders I found on ShaderToy and converted from GLSL to HLSL. All of the credits for the original shaders go to their respective authors.

As of now contains:

• Vignette
• Fisheye
• Blur
• Depth Grayscale
• Depth Blur (This one is kinda bleh)
• Depth Blur 2 (Better but limited in quality by Shader Model 2.0b)
• Film Grain
• Posterize
• Chromatic Aberration
• Radial Blur
• VHS Shader №1 (Probably won't be the only one)
• Video Glitch

Shader Damage Effects

An example addon to show how the shaders could be used by Lua developers: https://steamcommunity.com/sharedfiles/filedetails/?id=3443685887

For developers

I intend to make some/most/all of these have their own respective draw functions, outside of the hooks, for use in other addons, so here's the documentation for the functions. I will update it as I add more or if I change the functions.

render.DrawMercVignette( float outerRingPos, float innerRingPos ) - Draw a vignette using the framebuffer texture
render.DrawMercRadialBlur( float xScreenFrac, float yScreenFrac, float blurWidth ) - Draw radial blur on the screen
render.DrawMercFisheye( float strength ) - Draw fisheye on the screen
render.DrawMercFilmGrain( int blendmode, float speed, float intensity, float mean, float variance )
render.DrawMercChromaticAberration( float amount, bool centerfalloff ) - Draw chromatic aberration on the screen
render.DrawMercVHS1( float xoffset, float yoffset ) - Draw a VHS effect with variable chromatic aberration
render.DrawMercVideoglitch( float strength  - Draw a Video Glitch effect
render.DrawMercBlur( float strength ) - Draw a fullscreen blur
render.DrawMercDepthBlur2( float depthstart, depthend, strength ) - Draw a depth blur effect, works decently as DOF
