Question How to simulate "Clear Flags" in URP camera for frame accumulation?

Hello,

In the camera component there is the Clear Flag property which allows not to redraw the color buffer of the camera, and instead draw over it and have a "smear like effect".

I'd like to replicate the same effect on URP, where the Clear Flag is no longer an option:
how could I proceed? or what should I look into?

Furthermore, I'd be using the camera to render on a Render Texture, so I could use a custom shader (preferibly using Shadergraph) applied to the texture: is there a way to paint "over" the current texture without replacing the old one?

 

Hey, did you figure it out?

 

Hello, not really, I used some other weird workarounds actually (it's been a bit and I forgot what i did) but didn't find any obvious solution for this! Let me knwo if you find something out!
