Changelog

All notable changes to Pr3tz are documented here.

[Unreleased]

Minimum Blender version raised to 5.0 — bl_info["blender"] updated to (5, 0, 0). Blender 4.x is no longer supported. Drops all legacy compatibility shims:
- _get_action_fcurves now uses the Blender 5 layered Action API only (no action.fcurves fallback).
- Principled BSDF shaders use Blender 5 canonical input names directly: "Specular IOR Level", "Transmission Weight", "Coat Weight", "Coat Roughness".
- Removed "Specular" / "Clearcoat" / "Transmission" key-in-inputs guards.

Full modular rewrite: knot_animation.py split into 10 focused modules under knot_animation/
20 built-in shader presets (up from 7 in 1.x)
Per-knot material overrides — color, roughness, metallic, emission strength
Per-knot animation rates: spin phase, revolution phase, height pulse, scale oscillation
Smooth geometry transitions with Linear / Quadratic / Smoothstep easing
Random playlist generator with configurable min/max ranges for every parameter
Bake & Export operator with split-file support for distributed render farms (SheepIt)
Blender 5.0 layered-action API support (_get_action_fcurves compatibility helper)
FitTimeline and FitPlaylist operators
Global Reactivity factor for audio-reactive animation
preview_resolution / render_resolution split for fast viewport + quality renders
Camera shake baked to delta_location keyframes during export
Headless align_matrix monkey-patch for crash-free command-line rendering

Handler no longer uses bpy.ops or reads bpy.context.space_data — safe in all execution contexts
Material cache keyed by preset ID — no rebuilds on every frame

knot_animation.py: procedural torus knot animation with hardcoded 10-knot config list
7 shader presets
No playlist editor, no transitions, no export
