Compositor: Auto Render doesn't work
Closed, ResolvedPublic


System Information
Ubuntu 18.04

Blender Version
Broken: 2.79-2.79b
Worked: 2.78c or earlier

Short description of error
Compositor that Auto Render is enabled doesn't re-render or composite even when changes on 3D edits happen.
Confirmed with both Blender Internal and Cycles.

Exact steps for others to reproduce the error

  1. Open auto_render_test.blend
  2. On 3D viewport, edit something (e.g. Move default cube)

and then nothing happens with v2.79 (or later)...

Event Timeline

It does work when you are using the Defocus Node, using the Z-Buffer of the current scene. Could be that this is the only node that does actually trigger a render update, but then the Auto Render button would be quite misleading indeed.

Confirmed, would guess something went wrong in the update notifiers…

Bisecting points to rB4cf7fc3b3a4d032f0c0db632a46d40806e906cf1 as breaking commit. Not sure what went wrong there, that is rather large commit :/

Tried undoing some changes done in snode_set_context() but no success so far. @Lukas Stockner (lukasstockner97) this falls on your desk am afraid. ;)
