I have a few questions about the ACES workflow.

(1) When I configure Houdini to use ACES colour space in Edit-OCIO Settings and click Apply do I need to reboot Houdini for it to work?

(2) I believe the conversion of textures to ACES is done by Houdini 20 now, at least if you use Karma.
Do you have to manually convert them if you use Mantra? If so, how?

(3) Do you need to set any parameter in Karma or Mantra when rendering if using ACES?
