MarsSeed [1] filed a deletion request for mitsuba-blender-hg [2]: Defunct Blender 2.5 addon, doesn't work, as Blender 2.5 does not exist anymore, and even the AUR package of Blender 2.93 fails to build. Also package name is wrong: PKGBUILD uses a GitHub Git repo as source. Development discontinued since 2015.
