SlackBuildsOrg/graphics/yafaray-blender

This package lets you export your scene from within Blender to
Yafaray.

This script builds the Blender plugin, which is automatically
installed in /usr/share/yafaray/blender.

A link to the main plugin file is put in /opt/blender/script, but you
can change this editing the BLENDER_PLUGIN_DIR variable inside the
script.
