How to add bloom to Aline?

Hi, is there a way to add bloom to Aline ?

I tried to do it by implementing HDR colors using this thread:

How to implement HDR colors in Aline?

Hey, I’m enjoying ALINE and am exploring using it to supplement an in-game HUD. I’d like to put these into HDR color range, and I’ve already adjusted the injection point to accommodate this in HDRP. What’s a bit greek to me is what all needs to be modified to move to HDR color. My naive first guess was changing out from Color32 to Color in CommandBuilder.cs, but that didn’t change the output (and did appear to result in some subsequent rendering issues). It looks like there’s some direct memory…

That worked, but I had unexpected crashes.
I use URP and Unity 2021.3 LTS.
Thanks !

Hi

This is not possible out of the box. I think it might be possible by making ALINE render before post-processing effects (see also [URP] Drawings not visible in scene view when using a custom ScriptableRendererFeature - #4 by Jobus), but I have not tried this myself. This is kinda out of scope for ALINE.

Thanks you, I will check it out.

What about with HDRP ?

@thornebrandt I have not tried it with HDRP. It’s possible that there’s a hook that could be used there. But it is out of scope for ALINE, so I have not investigated this.

I fixed it by adding going to Packages/com.arongranberg.aline/DrawingManager.cs and swapping all CustomPassInjectionPoint.AfterPostProcess to CustomPassInjectionPoint.BeforePostProcess
