Question Creating a Vignette Effect in Unity URP without Post Processing

Hello Community members,

I had previously created a custom shader to be applied to the camera to give a vignette effect without post-processing, which was working great. However, when I recently converted my project to URP, the custom shader no longer seems to work. I'm not very experienced with shaders, so I'm looking for advice on how to create a vignette effect in URP using a similar technique or maybe a quad in front of the camera.

I'm hoping someone can provide me with some guidance on how to accomplish this. Perhaps someone has already created a URP-compatible vignette shader that they can share with me? Alternatively, I'm open to any suggestions for how to create the effect.

Thank you in advance for your help and advice!

 

2022.2+ have a full screen shader in shader graph, which would work the best probably.

 

Sorry, but my access is limited to LTS versions and as of now I have 2021.3.1f1 only.

 

This was my implementation earlier before switching to URP:
1I had created a script VignetteEffect attached to the camera:


2) this was the shader being used by the above script:

 

easy
Download transparent vignette texture from internet(in high resolution)
create a RawImage UI
apply the texture to it
then you can enable or disable it
change its alpha value over time to create fade in/out effect

 

That won't be good ad scaling with different resolutions tho. And a shader might use less GPU bandwidth, but that depends on the setup and device

 

Thats why we have 'Canvas Scaler'

 

But that will stretch the image, which can be undesirable

 

You can create a custom renderer feature to apply your shader to URP renderer at a specific point during rendering.

The vignette shader should work without modifications because it's an unlit shader.
