Your Blender asset. Tested inside the real engine.
Give it your .blend. FixMyMesh runs the imports in the Unreal, Unity or Godot installed on your PC, shows exactly what broke, fixes what it can on a copy and retests. No editor to open.
Windows 10 and 11 · 3 free tests at launch

Other checks read the file. FixMyMesh runs the import.
A validator reads your scene and predicts the result. FixMyMesh measures what each engine actually received.
Three steps. One window.
- 1
Pick a .blend and your engines
One file or a whole pack. No test project to set up.
- 2
Let it run
Real imports, in the background. No opening Unreal, then Unity, then Godot.

Read, fix, retest
Fixes go on a copy. The retest is one click.
What broke, where, and how to fix it.
Checked in every engine: geometry, scale, normals, UV, materials, textures, collision, LODs and more.
Export it as one HTML file to keep, or to send with your delivery. See a sample report
Normals · Unreal Engine 5.8
WARNING- What changed
- Smooth shading turned faceted.
- Likely cause
- The importer recomputed the normals.
- Fix
- Choose Import Normals and Tangents in Unreal, then retest.
Example
It fixes what it can. Then it proves it.
No more hunting for causes or redoing imports by hand. FixMyMesh fixes a copy, never your original, and retests it in the same engines.
Automatic
Safe fixes, like an unapplied rotation. Undone if they make things worse.
With your OK
Fixes that change your intent, like applying scale, wait for you.
Up to you
Engine settings stay yours: the report names the one to change.
Try it on your own files.
