I didn't check with Support, but it still seems to me that XPU Shadow Linking is not working.
I can see that with my current setup, same exact scene, just flipping between Karma CPU and XPU still allows one shadow to be casted where it shouldn't (see screegrabs below).

PS: This is on 20.5.654, but I just saw that it's still not supported [www.sidefx.com]

That's an area that I'm also very interested in!
I'd love to see this happen, but realistically, the VFX industry is just too deep in C++ so I don't expect anything to happen any time soon. For exploration purposes though I guess you could just write everything that you need in Rust (as a lib crate) and then compile it to a shared library that uses the C ABI (e.g.: https://valerioviperino.me/rust-cpp-ffi), then use the bare minimum of the HDK to use your library using the usual "blessed" C++ workflow (e.g.: https://www.sidefx.com/docs/hdk/_h_d_k__intro__creating_plugins.html).

Worth giving it a try for sure.. now you made me curious to see if it's feasible

This issue was resolved in 19.0.562.

Great to know!

In their replies, support told me:

Side Effects Support Ticket: #127553

Hello,

Anything above 19.0.589 should just work.

so I went with 19.0.720, and I can see the wrappers are back to being simple bash scripts.
