# ============================================================
# Installs Blender (3D modelling, animation, compositing) via
# Flatpak and POV-Ray (a classic CPU ray-tracer with its own
# scene-description language) via pacman.
#
# Blender is delivered as a Flatpak to get the upstream official
# build with all drivers and Python scripting enabled.
# POV-Ray comes from the official Arch repos because it is a
# small, self-contained CLI tool with no sandboxing concerns.
#
# These are grouped together because POV-Ray integrates with
# Blender via the Blender2POVray addon, allowing Blender scenes
# to be rendered with POV-Ray's photorealistic ray-tracing.
