HDRP VFX Reflection

I have an HDRP project and I created a screen reflection in sky and fog global volume, and I see that unity 2023’s vfx supports ray tracing. In the scene, ordinary vfx and objects can reflect normally, but particlestrip cannot.

Why is that?

In addition, I used shader graph to write a shape of SDF, but it can’t support reflection properly, and what is reflected is the shape of the model in the mesh filter.

Would you like to ask if there is a solution?

Hey, I know it’s not well documented (at least on HDRP side) but only simple primitives are supported in raytracing such as Quads, Triangles and Octagons. The rest is not and most probably won’t be anytime soon given the lack of resources on ray tracing side to make it happen.

There’s a little info on the What’s new in the VFX graph documentation here.
