System Information
Operating system: Windows 10
Graphics card: RTX 3060ti

Blender Version
Broken: version: 3.6.0 Alpha, branch: main, commit date: 2023-05-04 09:04, hash: e674e32aa122
Worked: version: 3.6.0 Alpha, branch: main, commit date: 2023-05-01 20:15, hash: 0652945dbda7

  • VDB volumes don't render in EEVEE and Cycles. Workbench works fine.
  • Volume modifiers generated and cached in previous versions still work in later versions.
  • Volume modifiers generated and cached in later versions don't work in neither.
  • VDB volumes created in later versions don't work in neither.

The first commit where I can reproduce the issue is 0de54b84c6 (@JacquesLucke), however I don't see anything directly related to volumes there.

Exact steps for others to reproduce the error

It turns out the issue is simply that the Principled Volume node no longer sets the Density Attribute default value.
So I guess it makes sense it was caused by the simulation nodes commit.
