Subject: [PATCH 1/3] blender: add updateScript
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change srcs -> src otherwise nix-update does not update the hash; we
don’t need srcs anymore, anyway, as there is now only one.

Subject: [PATCH 3/3] blender: update OptiX to match upstream
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Determining the current version of OptiX that upstream builds with is
somewhat non-trivial. In theory it is [read from the BuildBot
config][1], but I don’t know where that lives or how to view it. The
only way I know of to determine the version then is to inspect the
Blender BuildBot logs.

This change was determined by looking at the logs from the
`v440-code-daily-linux-x86_64` builder, `compile-gpu` step [logs][2],
where it had:

> -DOPTIX_ROOT_DIR:PATH=/home/blender/.devops/apps/NVIDIA-OptiX-SDK-7.4.0-linux64-x86_64
