FBX Scale Report

See what unit scale an FBX file declares, before the engine does

Blender add-on · Blender 4.2+ · GPL-3.0-or-later

Reports the unit scale declared inside every FBX file in a folder, and names the ones that are wrong. Reads the files and changes nothing.

What it does

Reads the file's own declaration, not what Blender made of it
Says what it could not read instead of staying quiet
Text, CSV and a self-contained HTML report
Works from the command line without Blender, exit code 1 on a broken scale

What it looks like

A report listing five FBX files, each with the unit scale it declares and a verdict of ok. — Every file gets a line: the declared factor, what it means in metres, and whether it is a problem.

A report listing files with broken scales first, marked bad, and a binary file marked unknown. — Problems come first, each with the reason. Binary files are reported as not read rather than skipped.

The same check run in a terminal, ending with exit code 1. — The same code without Blender, and an exit code a build pipeline can read.

Requirements

blender 4.2 or newer
python 3.9 or newer, for command-line use
os Windows, Linux, macOS

What it does not do

Read this before you decide. It is the reason the list above can be believed.

It does not fix the scale. Changing a factor is a decision about intent, and a tool that silently corrects it destroys work.
It does not read binary FBX. It says so, by name, rather than reporting a file it could not read as fine.
It does not modify anything — not the FBX files, not the scene.
