I’m encountering an issue where the “Offset Uniform Scale” parameter doesn’t work at all when importing character models in Unreal Engine 5.7.0. All import settings are default except for this scale parameter—no matter how I adjust its value, the imported character model doesn’t scale, and remains the same size as when Offset Uniform Scale is set to 1.
The same model imports normally in UE5.6.1, where the Offset Uniform Scale parameter works as expected to scale the model. I’m not sure if this is a bug in the new version or if there’s a new setting logic I’m missing. Could anyone help me figure out how to resolve this?
Current importer seems to be broken and not apply what I want. I found you can switch to the legacy importer by putting “interchange.featureflags.import.obj false" into the console for importing obj files. I have to also select "do not create new material" so that it doesn't automatically create and give it one.
I had the same problem as the original poster, “Offset Uniform Scale” and “Offset Rotation” were not affecting the imported object at all. Switching to the legacy importer as described here and worked perfectly to get those two parameters working again.
This does sound like a regression or change in the UE 5.7 FBX import pipeline, especially since the exact same asset behaves correctly in 5.6.1.
As a quick check, I’d try importing the mesh into a fresh 5.7 project and verify the FBX import settings with the same value while keeping the rest of the settings identical. It may also be worth checking the asset’s transform/scale before export and whether the skeletal mesh is being imported with an existing skeleton.
If the parameter has no effect at all—even with a large value like 0.1 or 10.0—while other import settings work normally, that would make a 5.7 regression more likely than an FBX setup issue. Comparing the same FBX in 5.6.1 and 5.7.0 is probably the best way to isolate it.
There might be something else at play here as mentioned by Neil.
I did a test on 5.7.4 from the launcher, on a new project, with a FBX containing skeleton and animation sequence. Uniform Scale is applied when the “Bake Meshes” option is ticked.
Which file format are you importing? Do you import the skeleton with it? Can you share the file with us in DM? Are you using the Interchange import, i.e does your import dialog look like this? Are you doing an asset import, importing the fbx file directly in the content folder?
