Showcase Fast Post-Processing for VR / Unity URP

In case anyone is interested and trying to solve the same problems, I wanted to share a blog post I wrote about how I implemented tonemapping and color grading in The Last Clockwinder.

The standard Unity URP post processing pipeline is written to use a secondary fullscreen pass, but instead, I made several modifications to move much of the post processing into the Forward Geometry Pass, along with the pixel shader.

You can take a look at the final code in the PR here:
https://github.com/AStrangerGravity/Graphics/pull/3

The shader modifications weren't tricky, but it took some work to make the SRP Pipeline support it as an extra mode. Our fork adds an extra dropdown in the pipeline settings to enable forward pass color transformations.

Happy to answer any questions!

 

What else is in this repo?
And is spacewarp supported?

 

This is our fork of the Unity/Graphics repo. We implemented a bunch of customizations for The Last Clockwinder, which you can peek at in the PR list.
- Forward Pass Post Processing
- Baked Specular Lighting
- Disabled Directional Light and Point Lights
- A custom Fade-to-Black global shader parameter that fades all shaders to black
- Alpha to Coverage for Alpha Cutout shaders
- Various shader optimizations that are hyper specific to TLC
- (Prototype) Custom Post Processing per Render Layer

Lastly, yes! There is an Application Spacewarp implementation on this unmerged branch:
https://github.com/AStrangerGravity/Graphics/tree/asg/john/spacewarp

We didn't ship with ASW though, because it had too many artifacts in our use case.

Note that this URP fork is fairly specific to The Last Clockwinder, and so you would probably want to cherry pick changes out of it, rather than using this fork wholesale. It's not intended to be a general pipeline for all projects.

 

Hi, I find this package on asset store: https://assetstore.unity.com/packag...g-color-correction-lut-blur-bloom-urp--129638
but can't apply for urp on vr meta quest headset, have anything for help me please ?

 

Contact the developer of that asset (or at the very least make a new thread, your question has nothing to do with this thread).
