HDRP/ShaderGraph Scene color AFTER the post effects

Unity Engine

Hello :slight_smile:

I’m trying to do a blur in UI, but for this I need to get the scene color AFTER post process are applied.

This is my shader. I’ve set my UI in screen space - camera. The UI works fine, but the result doesnt take into account the post effect

Here’s the result:

The middle is the UI (the colors correspond to the colors before the post effect). The outside is the color after the post effect.
How can I get the correct colors, after the post processes are applied?

Thanks!

I’m sorry to resurrect an old post, but i’m facing the same issue. Did you manage to fix it eventually?

This is a super old thread but I do not think there is a solution yet. From my understandings the textured used by the SceneColor node is captured before post processing, thus no post processing is applied when we use it.

A very temporary solution that I am using is to just draw the shader before post processing so the colors from SceneColor is also included, however this can create many more unwanted behavior.

Is it possible to gather the SceneColor based on the shader’s rendering pass, so that shaders rendered after post processing have SceneColor with post processing?
