Created attachment 223096 [details] blender on FreeBSD without volumetric Hi, Blender 2.91.0_1 from binary pkg and 2.91.0_3 from ports can't render volumetric in Cycles. Volumetric work with Eevee only actually. blender-ok.jpeg screenshot was taken from Obarun (ArchLinux without systemd). Volumetric work. blender-novolum.jpeg was taken from FreeBSD. Same result with 2.91.0_1 and 2.91.0_3. blender-novolum.blend is a simple blender file with a cube and volumetric shader "principled volume". This same file was used on linux and FreeBSD. There's no error in terminal.

(In reply to Bruno d'Arcangeli from comment #2) As we now have blender 3.4.1 in the ports tree, is this still relevant ?
(In reply to Kurt Jaeger from comment #3) Doesn't look to be, cycles volumetrics works now. I expected it to be related to the tbb changing to onetbb which broke openvdb (bug #264688), but I hadn't re-checked since that update.
