Any way to pull data out of VFX graph onto the CPU-side?

Hi all,

Wondering if anyone knows of a way to get any sort of data out of VFX Graph particles onto the CPU side. In my use case, I’m trying to get particle positions.

Open to any methods, even if they’re somewhat hacky or slow, as this is for a pre-baked thing.

It is possible with newer version of unity to pull some data with custom node and async readback.
I think there is example of something what should put you on right track.

For other readers - async readback is not instant, it’s “slow operation” and might not suit your use case.

Thanks heaps! Got it up and running. VFX-graph driven lightmapper (with a bit of texture creation on CPU side). Only generates an AO texture at the moment but that’s a later problem.
