I'm using the viewport's render preview.

The micro displacements don't update on node tree changes. The subdivision stays the same even when altering the scene.

Can I force all objects to update their subdivision on scene changes, or node tree changes?

  • $\begingroup$ While this is an experimental feature, the update functions are not a priority and they will probably only be coded when the microdisplacement gets water tight. It's possible, however to add a python script on NodeEditor updates to force the update. (probably it will be very slow, and possibly it can crash the system) $\endgroup$ – Secrop Mar 5 '17 at 23:38
  • $\begingroup$ @Secrop What should that script do? Attach a function to on_scene_update and toggle the preview mode to solid to rendered? $\endgroup$ – Leander Mar 5 '17 at 23:51
  • $\begingroup$ probably it would also be good to check if changes are in the nodeeditor only. Look in the scripts/addons/cycles... I think there's a function to update the engine (not sure thought) $\endgroup$ – Secrop Mar 6 '17 at 0:12
