# VNTG Shader Pack for Unity 6 URP
|
||
|
||
VNTG is a collection of PSX-inspired and CRT post-processing shaders built for Unity’s Universal Render Pipeline. These shaders were developed across multiple game jams and I hope to continue expanding on these in the future. I hope other developers can find it useful in their own projects.
|

|
||
|
||
## Installation
|
||
|
||
Download the proper `.unitypackage` file from [HERE](https://github.com/Colby-O2/VNTG/tree/downloads) and drop it into the `Assets` folder of your project. For rendering features, you can use the included VNTG renderer or add the PSX and CRT rendering features to your own. All settings can be found in the Global Volume.
