I'm trying to use an attribute paint in Unity, and according to the documentation you need to Enable Editable Node Tools in the Asset Options. That option doesn't seem to exist for me, however, using H19 + Unity 2021.2.3f1. Did the workflow change?

Fixed in Houdini 19.0.464 and updated the "Known issues" page: https://www.sidefx.com/forum/topic/81539/ [www.sidefx.com]

EDIT: Nevermind! it showed up but can't be a paint curve SOP

I am on 19.0.531 and still can't find the "Enable Editable Node Tools".
Is it not available in an object level hda?
