--- Comment #1 from Ben Beasley  ---
If this happens, it will require branching a large number of dependencies. Some
are conditional and can reasonably be omitted; some are conditional but should
really be included; and some are probably mandatory.

Some of those dependencies will have a mix of optional and mandatory
dependencies of their own, e.g. for usd:

The best scenario is to use the LTS release for EPEL 10. Testing a build using
"lite" release (-C./build_files/cmake/config/blender_lite.cmake . ),
OpenImageIO is currently unavailable in EPEL10 repository while avail on both
EPEL8 and EPEL9,

--- Comment #4 from Bartosz  ---
Hi,

I am Blender contributor and I would love to see Blender in EPEL 10.

The openvdb-devel is library needed for OpenVDB support, which is industry
standard for sharing Volumetric Data:
https://www.openvdb.org/

I think without that library the Fire, Smoke and Liquid simulations could not
work
(https://projects.blender.org/blender/blender/src/branch/main/extern/mantaflo...).

The simulations are currently disabled in EPEL 9 (Blender 1:3.3.21-1.el9). It
is displayed "Build without Fluid modifier".

Steps to reproduce:
1. Open Blender
2. Select default cube
3. From menu select: Object -> Quick Effects -> Smoke

Currently: "Build without Fluid modifier" is displayed.

Expected: Smoke is displayed. After hit Play, the simulation is performed.

I will investigate root cause of Fluid failure in EPEL 9

OpenImageIO and OpenColorIO needed to get available on EPEL 10 first otherwise
the build fails.

Would you mind opening a separate bug report for EPEL 9 version?
