URP-PSX-FORK (URP 14)

Checkout URP-11 branch for Unity 2021, URP 11 version.

I've been using this for a short while now and really enjoying it, so I've decided to do some janitorial work on the project and add some of my own touches.

First of all I upgraded the project to work on Unity 2022.3.17f1 and URP version 14. (It was working before just printing some warnings 🙂)

I Also edited some existing shaders to stop giving warnings for Shadergraph versions above 10 (custom lighting shader for example).

Check the releases page for the bundled .unitypackage file and setup instructions.

Changes

• Upgraded for Shadergraph version 14.
• Added new render feature for CRT Effect. (Screen bending, vignette, scan lines, noise and chromatic aberration)
• Added a new unlit shader with affine texture warping and vertex locking, unfortunately I couldn't get around to implementing custom lighting. Anyway this shader comes in two variants:
  • A Regular version similar to original unlit shader in this project.
  • PolyBrush version which supports PolyBrush texture painting.
• Added a couple useful subgraphs, a random color picker and voronoi center graph.
• Added a variation of the PBR shader that is transparent. (Only in URP 14 branch)

Notes:

• In newer versions of URP depth textures needs to enabled on the Render Pipeline Asset for fog to work.
• New Affine texture warping shader currently doesn't have a lit variant and unlit variant does not support custom lighting.
• Added scenes for both new shader variants and added CRT effect to all existing scenes.

Original Description:

URP-PSX

Playstation 1 era retro graphics plugin optimized for Unity's Universal Rendering Pipeline with Shadergraph. The aim of this plugin was to use Unity's new pipeline to create NPR (non-photorealistic) PSX-style retro graphics with the shadergraph as the basis for materials and URP's render features as the basis for post processing effects.

Features

The plugin comes fully-featured with a single lit/unlit graph where you can enable/disable features according to your needs (and even modify them). I segmented every feature into a subgraph to hopefully make it easier to just plug n' play.

Shadergraph:

• Lit/Unlit shader variants
• Specular Lit variant
• Camera-based vertex clipping
• Vertex snapping/Jittering
• Texture Pixelation for crushing texture resolution
• Color Precision for lower or higher color Fidelity

URP Render Features:

• Screen-space fog
• Screen-space pixelation/color precision adjustments
• Screen-space dithering

Note: Make sure you set the render features in the pipeline asset

Compatibility

Unity 2019.3.7f1 Universal Rendering Pipeline/Shadergraph (7.1.8)

Known Issues

• Unity's Shadergraph still has a long way to go when it comes to creating NPR effects. You might experience some lighting clipping issues if you are using the PBR master node. To fix it, I tweaked some settings in the URP pipeline asset settings so they are barely noticeable.

Support

I developed this plugin out of passion/nostalgia for retro ps1-style horror games. But, if you found this plugin useful and want to show your support, consider sharing it,buying me a ko-fi.
