System Information
Operating system: Linux-5.4.0-48-generic-x86_64-with-debian-bullseye-sid 64 Bits
Graphics card: GeForce RTX 3080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 455.23.04

Blender Version
Broken: version: 2.83.*; 2.91.0 Alpha, branch: master, commit date: 2020-09-28 12:56, hash: c6b904e972
Worked: No official release.

Short description of error
When rendering a transmittance volume render pass the result is the same as the scattering pass.

Exact steps for others to reproduce the error

  1. Start Blender
  2. Add an volumetric object + material
  3. Enable the Volumetric render passes.
  4. Look at the differences.

Oh, I just assumed this was just a current limitation that would be handled in D7010: EEVEE: Arbitrary Output Variables or I would have reported it earlier. My mistake.

@EAW: well it was implemented in 2.83.0 it is also in the demo video of 2.83. But we might have un-fixed it :-)
