VFX Graph support for self intersecting ribbons / strips?

[vade]

Hi

Firstly, thanks for sharing your work! This is nice!

Looking over the readme, i was curious if folks have OIT working with VFX Graph (apologies if thats obvious), specifically with URP + the strip particle rendering path.

Is it possible to use the OIT shader + render target in a VFX Particle Strip context?

Thank you!

Hi, thanks for your interest! I think there are two strict requirements and I am not 100% sure if they are supported in VFX Graph. The first is the support for RWStructuredBuffer, but it seems Unity added this recently in Visual Effect Graph v17. So you would definitely need to use that version or above. And the second requirement would be the use of Shader commands (ColorMask and earlydepthstencil). I don't think those are possible in VFX Graph. You might be able to somewhat working around it, by e.g. first rendering into the buffer and then setting the color to fully transparent, but it would be a workaround.

I thought about trying this a while back, but got too frustrated due to the lack of support in the engine for such specific shader and rendering implementations. Let me know if you are still interested to invest some more time on this idea.
