Retarget Batcher via ARP

NOTE: This tool requires that you already have Auto-Rig Pro installed in Blender. If you don't have Auto-Rig Pro, you can buy it here (I have no affiliation with makers of Auto-Rig Pro, but it is a pretty useful tool): https://blendermarket.com/products/auto-rig-pro

This extensions will reset a set of FBX animations to a common rest pose and export them in groups to a series of GLB files.

The purpose of this tool is to fixup Synty's animation libraries and package them into GLB libraries that are easily usable within Godot.

Known Issues

Root-motion animations need some work, but the in-place animations should all be good.

Tested Blender/ARP Versions

• Blender 4.3
• AutoRig Pro 3.73.29

Basic Instructions

• Install/enable Auto-Rig Pro in Blender.
• Download the extension release zip and drop into Blender to install.
  • fix_synty_anim_to_godot_with_autorigpro_v1_0_0.zip
• Purchase Synty animation packs and unzip Blender source files under a common directory.
  • Synty Store
  • The T-Pose from ANIMATION - Base Locomotion is needed (or you'll have to create your own T-Pose).
• Unzip all Synty animation packs you own under a common folder.
• Start new Blender project and delete all objects in the scene (the cube, camera, and light).
• Go to "Fix Synty Anim To Godot With ARP" tab in the side panel ("N" menu on the Viewport).
• Click "Batch Retarget" once to have "Anim Config CSV" automatically setup with preconfigured CSV that references all known Synty animations.
• Set "Import Path" to root folder containing all your Synty animations.
• Set "Export Path" to root folder that will contain all exported GLB files (one for each "group" name in the Anim Config CSV)
• Click "Batch Retarget".
• Wait a while (maybe 20 minutes on a reasonably fast machine).
• Your export path will now contain GLB files usable as animation libraries in Godot.

To use the GLB files in Godot:

• Drag and drop GLB files into your Godot FileSystem.
• Select each GLB file, go to "Import" tab.
  • Change "Import As" to "Animation Library"
  • Check "Import as Skeleton Bones"
  • Check "Trimming", "Remove Immutable Tracks", and "Import Rest as Reset".
  • Click "Reimport"
  • Click "Advanced"
  • Select "Skeleton3D" in scene browser. Create bone map (or use synty_anim_bone_map.tres in extension folder)
  • Click "Reimport"

To add animations to your character:

• With AnimationPlayer for your character selected:
  • In Animation tab, click Animation button then "Manage Animations"
  • Load library and then pick one of the GLB files you imported.

Notes about generation of synty_anim_metadata.csv

• List was generated by initially crawling folder, dumping list of FBX names, and remove non-animation FBXs.
• loop column was calculated in Excel as follows:

=AND(NOT(OR(ISNUMBER(SEARCH("_Begin_",A2)),ISNUMBER(SEARCH("_End_",A2)),ISNUMBER(SEARCH("_ReturnTo",A2)),ISNUMBER(SEARCH("_To",A2)),ISNUMBER(SEARCH("_Enter",A2)),ISNUMBER(SEARCH("_Exit",A2)))), OR(ISNUMBER(SEARCH("Idle",A2)),ISNUMBER(SEARCH("Walk",A2)),ISNUMBER(SEARCH("Run",A2)),ISNUMBER(SEARCH("Sprint",A2)),ISNUMBER(SEARCH("Shuffle_",A2)),ISNUMBER(SEARCH("Crouch_",A2)),ISNUMBER(SEARCH("_Additive_",A2)),ISNUMBER(SEARCH("_Loop",A2))))

• root_motion column was calculated in Excel as follows:

=OR(ISNUMBER(SEARCH("RootMotion", A2)),ISNUMBER(SEARCH("_RM_", A2)))
