when a file is missing from a VFX graph the missing node is highlighted in the graph itself

I’m attempting to lift some of the gorgeous VFX samples from HDRP to URP and this is the result.
So I’m trying to find that vfxparticlelitplanarprimitive in the vfx graph and can’t see it. (search in the graph would be good)
Double clicking this error message leads nowhere.

Volumetric : Exception while compiling expression graph: System.IO.FileNotFoundException: Could not find file "z:\__tests\visualeffectgraph-samples\library\packagecache\com.unity.visualeffectgraph@8.2.0\shaders\renderpipeline\universal\templates\vfxparticlelitplanarprimitive.template"

Hey @laurentlavigne ,

The key is this bit here: vfxparticlelitplanarprimitive

We do not have lit particle support for URP at the moment, though it’s planned for next year. Many of the VFX HDRP samples use lit outputs, some use distortion output (also HDRP specific) and you will not be able to convert them to URP. If you don’t need them to be lit, right click on the lit outputs while in HDRP, select convert, and convert them to a non-lit version before attempting to port them to URP.
