Post Processing Image Effects?

[CodeMonkeyYT]

Hey everyone,

From what I understand right now it’s not possible to do Post Processing effects in Shader Graph correct?
In 2019.3 with the upgrade to URP that will come bundled with the Post Processing stack is that going to be doable?

Thanks!

Anyone knows?
So far it seems the only way to do Shader Graph image effects is to place a quad right in front of the Camera or use a RenderTexture.

I’m not sure about post processing effects but you can always add a Renderer Feature and apply a material to it so it gets applied as an image effect to all the objects in the scene.

Hi @CodeMonkeyYT
Not possible at the moment (afaik), there was a custom implementation for 2018 last year, but it does not function in 2019, I guess the api has become more restrictive. Maybe there will be support in 2019.3. But I really hope we can write custom effects with code just like in HDRP. It gets problematic quickly with complex effects if we have to rely on Shader Graph only.

See these links for more info:

Shader Graph image effects for the Postprocessing stack

Edit: I moved this experiment to a separate repo here: GitHub - iBicha/ImageEffectGraph: Image effects for post processing stack created with shader graph for Unity ImageEffectGraph WeepyScaredKitty As an experiment, I threw this together to see how nice it would be to edit Postprocessing stack effects in shader graph. Since effects are used to be done by transforming a source texture into a destination texture through a shader, The idea is to have a “Main Texture” source input node, and an …

Yeah I saw that link when I was searching for it but apparently it’s been deprecated. I’m hoping with 2019.3 we will have an official way of doing it.

I completely forgot about the Renderer Features, that might indeed be the way to do it. Thanks!

Hey monkey, that might help you

I’m also searching for a proper way to implement image effects. Good luck.

I ended up doing exactly that and looks awesome. Just adjust the quad 0.02 on Z, turn of shadow casting, use unlit shader, etc. and voila.
