FAMILIAR PROBLEMS. SMALL FIXES.
Almost ready.
Just one thing looks off.
You found the model. You found the animation. Get past the little mismatches that stop you using them.
Keep the look.
Standing right.
Moving wrong.
The character stands normally, but its arms or legs turn the wrong way with another animation. Match a compatible rig, then try the motion.

Included in Trial
Your Blender model stays as it is.
Interactive illustration, not a live Blender or Unity connection. The right pane illustrates what the imported model can look like in Unity; actual results depend on your export and import settings. It does not automatically repair every import. Full features are labeled.
INSIDE BLENDER
What the panel actually looks like.
Three views of the same panel: static models, rig matching, and the free trial.
STATIC MODELS
Size, direction, origin.
Three buttons, each applied to a copy — the original keeps its shape and materials.
RIGGED MODELS
Two rigs, one direction.
Point at the model rig and at a reference rig that already animates; matching fixes the bone axes so the same motion lands the same way.
FREE TRIAL
Start with orientation.
No time limit and no usage limit on the trial. Rig matching and reference motion are part of Full.
ONE SIMPLE START
Try one fix.
See what comes next.
The trial works on your own static models. Keep the result, export it normally and use it as often as you like.

A good fit for this trial
Trial: static models
Use a static mesh. Imported Empty parents and custom normals are supported. Prepare orientation, export an FBX, and check the result in Unity.
Full: compatible rigs
Full matches rigs with matching bone names, hierarchy and compatible resting shapes. It also handles overall direction and uniform size differences.
Tested on macOS with Blender 5.2 and Unity 2022.3. Downloaded samples were checked in Blender; Unity checks use generated FBX samples.
Before you start
What happens to my originals?
The add-on creates a separate result and hides the originals while you check it. Select the result and use Restore original to remove it and bring the originals back.
Is animation matching included in the trial?
No. The free trial includes static model orientation correction. Rig matching and reference motion belong to Full; you can preview them in the website demo.
