I tried to do a minimal build first and even that was much work. From now on things can be added incrementally, this should be much easier.

Moonray works, but why hd_render(hdMoonRay) is not packed?

Should be fixed now.

Can't build

ISPC v1.28.1 resolves all issues. Patching is not necessary anymore.

It seems to me that a few dependencies are missing: libmicrohttpd cppunit qt5-base qt5-script openimagedenoise usd and AUR one: random123

I updated the PKGBUILD, thanks.

moonray has to be started like this:

moonray -threads 24 -out bla.exr -size 128 72 -dso_path /usr/rdl2dso/ -in scene.rdla -in scene.rdl

ISPC v1.28.0 has to be patched for moonray to work: https://github.com/ispc/ispc/issues/3545
