@bartus are you on freenode irc or something? I would like to talk to you about your PKGBUILD and i don't want to clutter this comment section.

@bartus so are you saying if I remove optix after installing blender, Cycles OptiX device should continue to work without problems? Also isn't this package and yours are practically same? Should we merge them?

@kureta Shouldn't Optix go in to makedepends. Optix v7.0 is header only ( symbols are pulled from the drivers)

@bartus I've already modified PKGBUILD, compiled, installed, and tested optix rendering on an RTX graphics card. Everything works fine.

Hi! I have modified your PKGBUILD file a bit. Specifically:

• removed cmake flags that are no longer applicable

    -DWITH_GAMEENGINE=ON \
    -DWITH_PLAYER=ON \

• Added optional dependencies for OptiX and Open Image Denoise Support

    optdepends=('cuda: CUDA support in Cycles'
                'optix: OptiX support in Cycles'
                'oidn: Intel Open Image Denoise support in compositing')

• Added logic for detection of these optional dependencies

    # check for optix
    _OPTIX_PKG=`pacman -Qq optix 2>/dev/null` || true
    if [ "$_OPTIX_PKG" != "" ]; then
        _EXTRAOPTS="$_EXTRAOPTS \
                    -DWITH_CYCLES_DEVICE_OPTIX=ON \
                    -DOPTIX_ROOT_DIR=/opt/optix"
    fi

    # check for open image denoise
    _OIDN_PKG=`pacman -Qq oidn 2>/dev/null` || true
    if [ "$_OIDN_PKG" != "" ]; then
        _EXTRAOPTS="$_EXTRAOPTS \
                    -DWITH_OPENIMAGEDENOISE=ON"
    fi

Maybe you can incorporate these changes into your PKGBUILD too.

@fbrennan: Consider updating pkgver scheme to preserve consistency across different blender packages in AUR.

pkgver() { cd "$srcdir/blender" printf "2.81.r%s.%s" "$(git rev-list --count HEAD)" "$(git rev-parse --short HEAD)" }

This would make repology versions report more usable

thanks ;)

Thanks guys, I'm working on getting it to build myself with the new changes. A state of flux is an understatement, the new development branch differs significantly from the old one so please allow time for things to stabilize :-)

This is now no longer the blender-2.79 branch. Recently blender dves have moved the blender-2.8 code into master (this PKGBUILD compiles from master) and the PKGBUILD and build options haven't been updated yet.

Things are currently in a state of flux so it may take a while to get things worked out.

I got this to build by adding the following changes to the PKGBUILD:

Note I'm not sure if python-numpy should be depends or make-depends, so I added it as depends in the diff.
