Question How to blur a render texture

Hello,

I'm looking for a way to blur an input render texture (in my case from the camera) by applying a material with a blur shader to the original render texture and store the result in a different output render texture. I would like to use that resulting render texture in UI toolkit to blur the background.

Any idea on how to achieve this? I've been looking through a bunch of threads but without success so far.
Would appreciate any kind of help or direction.

Thank you

 

I am no expert, but I have not had much luck combining different shaders. My default would be to put a pane of glass (transparent material) just in front of the video rendering material and put the blur on that.

 

This example should pretty much do 80% of the work for you , it's a custompass example applying a gaussian blur :

If you wanna use your own shader , looking at the BlitTexture in the Blitter class should be a good start
