Short description of error

**UPDATE**
so the bottom line of this seems the be the 4th input "Density Attribute" on the "Principled Volume" Shader. When adding this Shader the Density Attribute is pre-set to "density" which did not cause any issue on the "Worked version" mentioned above.
However, on the newest build "broken" having this default value "density" filled in prevents the Principled Volume Shader from working at all. Removing the value fixes the issue.
This should not happen considering it comes with this value prefilled by default.

"Principled Volume" node not working anymore in EEVEE.
"Volume Scatter" node works.

"Principled Volume" works fine on 79f67acccb from 24th march.

Exact steps for others to reproduce the error

plug "Principled Volume" into World Volume.

I can not reproduce this on my end (Linux, AMD).

@LazyDodo can you reproduce this?

after some more testing: turning up the "Emission Strenght" makes the volume appear with the "Principled Volume" Shader. so it has to be somewhere between the "Principled Volume" Shader and "Volumetric Lighting in EEVEE.
"Principled Volume" works in Cycles btw.

Also cannot reproduce, in this file, "Scatter" and "Principled Volume" both work:
#63377.blend

[only thing I did was to remove the "density" attribute]

@Tysa: can you confirm that above file is working on your side?
If so, could you upload your file [which is not working] here?

yes, removing the "density" attribute makes it work. this is weird tho. this was not needed on the old build i used from 24th march.

not_working_volume.blend

this is the not working file. its really just the default scene, with volumes turned on in eevee settings and principled volume in world output

Yeah that's fine, but when a bug goes to confirmed it's assumed the triage team has assigned it a developer, when you put it on confirmed yourself, it's more likely it's gonna fall through the cracks. Triage team won't look at it cause it doesn't need triage, developers won't look at it since it's not listed on their todo list of bugs

Just so it is helpful to track the cause, I'm reposting the version details I posted in the other thread (#63468).

Not Working for me in the build 009dbc2bc9 (dowloaded today: 10 April), d2d84132dd (April 7) and 700346d377 (Downloaded April 2).
Working in 1ae6aaad43 (March 22)

And yes I'm talking about the PV Shader in Eevee, not cycles. Cycles is fine.

My HW: Windows 10 64-bit, AMD Vega RX64

i edited OP a day or two ago with a workaround. check if PV works when you remove the word "density" on 4th input "Density Attribute". @SomeAB

yes, I have checked on my side. That workaround is working in 009dbc2bc9 . Thanks for pointing out.

Hi guys, I'm new here but I was looking for solutiuons to my problem and wound up here. I think it's relevent?

When I was following a tutorial on how to create Nebula's to learn about Volumetrics everything was working out ok at first and then suddenly my cube became a full volume and no matter what I did to the noise textures it remained so.

I closed the program and restarted from the beginning a few times and continued to have the same problem.

I read the principled node was broken so I unplugged it and plugged the rest of my network into the meterial output and it seemed to work fine. So I plugged the principled node back in and it seems to be working again for some reason.

I don't know if this is already noted or not.
