This repo contains nix flake that builds openmoonray from this repo
However, dependency versions were updated compared to official description, everything seem to work still, however was not extensivelly tested.
this will link with glibc-2.37
Building
just nix build
NOTE: THIS IS A STANDALONE BUILD
meaning all the tools will work, such as moonray and hd_render (see source docs)
BUT
to make hydra delegate work with houdini - it has to be reconfigured to use houdini's own USD
which is pain
Examples
# first build it
nix build
# then use script provided to initialize shell environment
. ./result/scripts/setup.sh
# download some examples, rdla or usd
# to render rdla
moonray -in /some/file.rdla -out image.exr
# to render usd
hd_render -in /some/usd/file.usd -out image.exr
Notes:
I don't have NVidia cards, so this package does not contain options to build with Cuda+Optix YET.
Upgrade notes
Overall it seems like a bunch of dependencies may be updated to more modern versions without a need to change anything in openmoonray repo, however certain problems were discovered:
openimageioat some point introduced forward declarations of Vec and V3f in texture.h that make it incompatible with openmoonray's code as is. I think currently i've picked the lates openimageio release without that changejsoncppliterally uses the oldest available release and cannot be updated because openmoonray code uses implicit cast from const iterator to non-const one, which was a bug in jsoncpp and was fixed in the very next release.usdof version 23 was causing compilation errors too... do not quite remember the nature of those issues...
