Scaled model looks like an alien

Hello,
I'm using the "upper lower body" model to do a series of tests.
I have added a series of markers to the model,
- Original model with markers
- Original.png (175.03 KiB) Viewed 381 times
and when scaling it completely deforms the body.
- scale model.png (144.86 KiB) Viewed 381 times
However, if I use the "rajagopal2015" model, the scaling does it correctly.
Does anyone know why it happens?
Thank you

Thanks for the response, it has been very useful. Although I had to do the scaling with version 3.3 of opensim, with version 4.0 it did not work for me

Now when making the inverse kinematics fails and the following link appears:
InverseKinematicsTool Failed: AssemblySolver::assemble() Failed: SimTK Exception thrown at Assembler.cpp:871:
Method Assembler::assemble() failed because:
Optimizer failed with message: SimTK Exception thrown at InteriorPointOptimizer.cpp:261:
Optimizer failed: Ipopt: Maximum iterations exceeded (status -1)
Assembly error tolerance achieved: 0.00391609566089032 required: 1e-006.
Does anyone know why?
