Warning: GetRefFrame Contained scale

hello.

after rebuild the Physics asset of my character i got this warning (lots) each time i open the physhics asset.

LogPhysics:Warning: FConstraintInstance::GetRefFrame : Contained scale.

What mean?

Bump! nobody can explain a bit what mean?

FTransform FConstraintInstance::GetRefFrame(EConstraintFrame::Type Frame) const
{
FTransform Result;

	if(Frame == EConstraintFrame::Frame1)
	{
		Result = FTransform(PriAxis1, SecAxis1, PriAxis1 ^ SecAxis1, Pos1);
	}
	else
	{
		Result = FTransform(PriAxis2, SecAxis2, PriAxis2 ^ SecAxis2, Pos2);
	}

	float Error = FMath::Abs( Result.GetDeterminant() - 1.0f );
	if(Error > 0.01f)
	{
		UE_LOG(LogPhysics, Warning,  TEXT("FConstraintInstance::GetRefFrame : Contained scale."));
	}

	return Result;
}

As you see Constraint’s transform contains Scale component, but I don’t know how You did that;) Maybe your skeletal mesh is broken or You upscaled constraints in PHAT:)

I have same issue

"

LogPhysics:Warning: FConstraintInstance::GetRefFrame : Contained scale.

"

Is there any way to fix it?

In my case the reason was that my Blender model had objects whose scale was not 1.0, 1.0, 1.0. I had to ‘Apply Object Transform’ (select ‘Scale’) in Blender on the scaled objects, re-export and then the error was gone.
