2022-11-21 Eevee/Viewport Module Meeting

Practical Info

This is a weekly video chat meeting for planning and discussion of Blender Eevee/viewport module development. Any contributor (developer, UI/UX designer, writer, …) working on Eevee/viewport in Blender is welcome to join.

For users and other interested parties, we ask to read the meeting notes instead so that the meeting can remain focused.

Blender 3.4

Most time this week was spend on bug fixing for the upcoming release.

  • Worked on implementing custom int attributes support for the draw manager.
    Reworked the way the GPU subdivision shaders are cached/retrieved.The previous method ignored the defines parameter after the first shader compilation. (T102076) (D16420) (needs review)
  • Added support for optimizing-out unused inputs in Mix nodes (ie. when the mix factor is 0 or 1).
    Needed to avoid setting wrong/unwanted material flags. (T100904) (D16533) (needs review)
  • Fixed an issue with shadow maps bounds ignoring the light “Volume Factor” (T101965) (D16513).
  • Updated the EEVEE modulo node to match Cycles/OSL behavior (T101562) (D16497).
  • Improved the name of code-generated shader variables in debug builds (D16496).
  • Investigated and closed/discarded T100420, T97024 and T101197.
  • Fix hair/curve drawing artifacts when workarounds are enabled [5be3a68f58]
  • Regression: EEVEE: AMD driver 22.7.1 - 22.8.2: Volumes created from VDB and Geometry Nodes show artifacts [51914d4a4a]

Viewport Compositor

  • We should find a stakeholder for the project to work as part of the project to help make the right decisions.
  • Fix T102554: Crash when Use Nodes is enabled. rBdd260d2f.
  • Extend option to enable realtime compositor. D16509.
  • Disable Realtime Compositor on MacOS. D16510.
  • Add usage option to Composite node. D16531.
  • Warn about unsupported setups in Realtime Compositor. D16508.
  • Did more work toward support the Glare node.
  • UI/UX changes are still needed and have to be prototyped (Error messages in tooltips, Error messages in nodes)
    • Current implementation of error messages in nodes is to tailored towards Geometry nodes. After checking with the Nodes module we will hard code the messages we need for now.
    • Colored error messages in tooltips are not supported yet, although most things in the UI module are hackish we could also use a label in stead of a tooltip.
    • We prefer to use a Is Viewer node to be more generic solution (proposal was to have a similar option as the Material output node. )
