URP-PSX VS psx_retroshader

There is a great repo of URP shaders for the psx look on github

I don't know if I'm too stupid to understand what a shader is but whatever. I've heard you have to apply as a material to objects. However when I have a shader like this one https://github.com/Kodrin/URP-PSX. Would there be any way to just have it on the whole game? Like a filter basically. I'm new

Okay this is a shader in Unity which replicates the vertex jitter from the PS1. I'm finding it tricky to get the lighting and coloring right, so it will take a lot of experimentation. Link to the shader is here: https://github.com/Kodrin/URP-PSX

It's a PSX shader I found. There's actually three that I know of (1, 2, 3), but I only used the first because it seemed simplest to get running. I'll probably mess with the others down the line, too.

I searched the web and found the following shader. It's a Unity Shader and I'm not exactly sure what it does intuitively, but maybe this is a good start?

For Unity you can use - https://github.com/dsoft20/psx_retroshader

There is a PSX shader made by José Guerreiro in 2015. Not saying that's what this is but the results with it come pretty close. It was used in version 103B of Ultrakill. it can be found here: https://github.com/dsoft20/psx_retroshader

// https://github.com/dsoft20/psx_retroshader/blob/master/Assets/Shaders/psx-vertexlit.shader const vec2 base_snap_res = vec2(160.0, 120.0); vec4 get_snapped_pos(vec4 base_pos) { vec4 snapped_pos = base_pos; snapped_pos.xyz = base_pos.xyz / base_pos.w; // convert to normalised device coordinates (NDC) vec2 snap_res = floor(base_snap_res * precision_multiplier); // increase "snappy-ness" snapped_pos.x = floor(snap_res.x * snapped_pos.x) / snap_res.x; // snap the base_pos to the lower-vertex_resolution grid snapped_pos.y = floor(snap_res.y * snapped_pos.y) / snap_res.y; snapped_pos.xyz *= base_pos.w; // convert back to projection-space return snapped_pos; }

However, a big part of the art inspiration for this project is PS1 style graphics. Because of that, I would really like to use this PS1 style shader for Unity.

I don't know if I should add this shader to make the textures look like the ones on PS1 even though petscop clearly doesn't look like this: https://github.com/dsoft20/psx_retroshader
