Short description of error
Mantaflow during baking smoke simulation produces two kinds of vdb files -
data
andnoise
. Second is only baked ifnoise
option is set before baking. Those cache files baked for each frame can be then imported as individual objects into Blender with import vdb volume for further work.When the simulation is baked with Blender
be81690b73
and those vdb files are imported into a scene then Cycles and EEVEE does not rendernoise
vdb files. They are visible in the Outliner and are rendered properly in Workbench.I also checked and those files are not visible in Blender 3.3 but I didn't tried to bake the simulation in other versions than master.
Exact steps for others to reproduce the error
Rendered
fluid_noise_0005
object.Alternatively for triaging purposes:
Smoke Domain
object selected go to Properties -> Physics -> FluidCache
set temporary path for cache files (could be whatever)Cache
hitBake All
and wait for bake to finish.Shift + A
-> Volume -> Import OpenVDB and select one vdb file fromdata
cache folder and one fromnoise
.Rendered
.noise

Principled Volume will by default use the
density
grid as density. In these files there isdensity_noise
instead, which can be manually set in the shader node.Ah, indeed.
If that is by design then I guess this report can be closed.
Sorry for the noise (pun intended).

If using
density_noise
as theDensity Attribute
in the shader works correctly, then I would assume this can indeed be closed (@brecht: correct me if I am wrong).I think so. If anything should be fixed it's in mantaflow, and that's not rbeing maintained.
