I’m aware of `StorageBufferAttribute` and`StorageInstancedBufferAttribute`, but couldn’t find any equivalent to `InterleavedBuffer`,`InstancedInterleavedBuffer`or `InterleavedBufferAttribute`.

I assume you’re trying to write _into_ the interleaved buffer attribute with TSL, not just to read from the buffer with a TSL-based shader? It doesn’t look like TSL-based writes to interleaved buffers are supported today, as far as I can tell.

Exactly, read/write operations on both CPU and GPU. But it’s not a big deal, I’ll stick with individual attributes form the moment, TSL is already amazing as is, it’s doing all the heavy lifting for me.
