Particle SOP 'id' attribute glitchy

I can’t seem to make the particle id work with a SOP To CHOP.

Am I missing a step or is it a bug?

  1. turn on particle id in the Particle SOP
  2. turn on Custom in SOP To Chop
  3. type id into the attribue scope field

EDIT:

Ok something fishy definitely going on. If I re-open this file, the originally placed particle sop gives the particle id, but a newly created one gives the same error as before restarting TD:

Hey @matijaerceg

the attribute is only added at the initialization of the particle system - so you have to hit the reset parameter after turning this on. I’ll make a note in the documentation about this…

cheers

Ah okay, thanks. It was very disorienting.

Why not just automatically reset the Particle SOP when that setting (and any others that require a reset) is toggled?

Changing to RFE instead of bug.
