Auto Rigging for Godot 4: RigMaster vs Mixamo vs Rigify vs AccuRIG
Last updated 2026-11-02 · Written by the Cosindra team; see the disclosure below.
For a humanoid in Godot 4, RigMaster rigs your mesh in the browser from 18 joint markers and exports a Godot glTF whose 53 bones, Root included, already carry SkeletonProfileHumanoid's names, so every required bone maps by name at import; in our test in Godot 4.7.2 on November 1, 2026, all 17 required bones mapped and borrowed clips matched the source within about a degree at the arms with Fix Silhouette on. A rig costs 15 credits on a free start, and the Godot conversion adds none. Mixamo (free with an Adobe account) and AccuRIG (free) rig to their own skeletons, which Godot's importer tries to map by bone-name patterns when you pick the humanoid profile, and Rigify in Blender (free and open source) is the hand-built route; we have not tested those three in Godot. Godot itself is free and open source under the MIT license.
Disclosure: we build RigMaster. Facts about the other tools were read on their official pages on November 2, 2026 (Mixamo's on November 1, 2026); the Godot steps follow Godot's own documentation and our test.
Is it free and what does it cost?
Cosindra is free to start with no card: the Starter plan gives 30 credits a month, eligible new accounts also get 50 one-time signup credits, and Starter includes one free download shared across products. Paid plans start at $9.99 a month (BYOK, 150 credits a month), and one-time credit packs cost $5 for 50 credits, $10 for 100 or $20 for 200, with credits that never expire. In RigMaster a rig costs 15 credits with 5 free polish rounds, and the Godot conversion adds no credits. For the others: Mixamo's own site offers "Sign Up for Free" (read November 1, 2026); Reallusion calls AccuRIG "a free software"; Blender is free and open source software; Godot is free and open source under the MIT license (official pages, read November 2, 2026).

What Godot needs from a humanoid rig
Godot plays an animation by bone path, so two rigs share clips only when their bone names and rest poses agree. At import you give the Skeleton3D a BoneMap with SkeletonProfileHumanoid (56 bones, 17 of them required), and the Rest Fixer lines the rests up with Godot's T-pose; Godot's documentation says Fix Silhouette is not needed for T-pose models and should be on for A-pose models. Godot recommends glTF, can import a .blend file by calling Blender, and imports FBX through ufbx.
RigMaster's Godot glTF: the route we tested
RigMaster (ours) converts the finished rig on the server, free: 53 bones, Root included, every one a profile bone with the profile's own parent, so the BoneMap fills in by name, with up to 8 bone weights per vertex like the Unreal FBX. In our test on November 1, 2026 in Godot 4.7.2, with Quaternius' CC0 animation library as the source, the clips played with the arm segments within 1 degree of the source and the legs within 3.2 degrees once Fix Silhouette was on; without it the arms sat 55 to 61 degrees off, because the rig rests in Manny's A-pose. The same rig also gives you the UE5 Manny FBX and a Mixamo-named FBX.
Mixamo, Rigify and AccuRIG in Godot
Mixamo is the most common free source of a rig and clips; in Godot you set SkeletonProfileHumanoid on its skeleton and let the auto-mapping match its names, which Godot's docs say works by pattern and can be fixed by hand. Rigify builds a full control rig in Blender for free, and its deform bones are what you export and map. AccuRIG is a free desktop rigger that saves FBX and USD. We have not tested any of these three in Godot, so check the BoneMap for red entries whichever you use.
Honest limits
RigMaster's Godot file carries a Root bone, but we have not played root motion clips on it in Godot, and we tested Godot 4.7.2 on macOS only. All the auto-riggers here are for humanoids. Starter includes one free download, shared across products. More downloads come with a paid plan (from $9.99 a month for 150 credits) or a one-time credit pack ($5 for 50 credits, $10 for 100 or $20 for 200), whose credits never expire and which opens downloads for 15 to 30 days.
Who should pick what
RigMaster
You want a humanoid that maps to Godot's profile by name with no renaming, tested in Godot, from markers you place in the browser.
Mixamo
You want a free rig plus a free animation library, and checking the BoneMap yourself is fine.
Rigify
You work in Blender, want a full control rig, or the character is not a humanoid.
AccuRIG
You want a free local rigger with good hands and will map its bones in Godot.

Common questions
Is it free and what does it cost?
Cosindra is free to start with no card: the Starter plan gives 30 credits a month, eligible new accounts also get 50 one-time signup credits, and Starter includes one free download shared across products. Paid plans start at $9.99 a month (BYOK, 150 credits a month), and one-time credit packs cost $5 for 50 credits, $10 for 100 or $20 for 200, with credits that never expire. In RigMaster a rig costs 15 credits with 5 free polish rounds, and the Godot conversion adds no credits. For the others: Mixamo's own site offers "Sign Up for Free" (read November 1, 2026); Reallusion calls AccuRIG "a free software"; Blender is free and open source software; Godot is free and open source under the MIT license (official pages, read November 2, 2026).
Does Godot have an auto-rigger?
No. Godot retargets: a BoneMap maps the skeleton your file already has to SkeletonProfileHumanoid. Rig the mesh in another tool first, then set the BoneMap at import.
Do I need Fix Silhouette in Godot?
Godot's documentation says it is not needed for T-pose models and should be enabled for A-pose models. RigMaster's rig rests in an A-pose, and in our test Fix Silhouette took the arm error from 55 to 61 degrees down to about 1 degree.
Can I play Mixamo animations on a RigMaster character in Godot?
Godot can share clips between any two rigs mapped to SkeletonProfileHumanoid, so it should work once the Mixamo file has its own BoneMap. We tested with a CC0 animation library, not a Mixamo download.
Is Cosindra free, and what does RigMaster cost?
Yes, you can start free with no card. The Starter plan gives 30 credits every month, and eligible new accounts also get 50 one-time signup credits. A rig costs 15 credits and includes 5 free polish rounds, so the 80 credits of a new account's first month cover 5 rigs. Starter includes one free download, shared across products, and Apply in UE5 through the free desktop app is never download-locked. More downloads come with a paid plan (from $9.99 a month for 150 credits) or a one-time credit pack ($5 for 50 credits, $10 for 100 or $20 for 200), whose credits never expire and which opens downloads for 15 to 30 days. The face rig is a paid-plan feature.
