blender+hiprt is not a build blocker, it is an optional blender feature.
blender+hiprt feature has not been tested on rawhide, and we are at the ending weeks F42 release.
i will not have time to test this feature in rawhide, let alone F42.
isn't it too late to get this in ?

You are right. Maybe update it once we tested hiprt on Rawhide or on one COPR repository (https://copr.fedorainfracloud.org/coprs/g/designsuite/blender/builds/) as  enthusiasts will like be eager to fully test such features.

Blender 4.4.3 tested with HIPRT enabled

The good news is the latest HIPRT 2.5 runs well on Blender 4.4.3 for Fedora 42 through Radeon RX 6950XT with no noticeable regressions. I think it is safe to update HIPRT to the latest version on Fedora 42 as the current version lacks math libraries for Rendering Cycles Engine.
