Hello,

I am currently working with the MASI model. I scaled the model with the marker data. Unfortunately, I found that some body parts were missing after scaling although the scaled model works perfectly. What can be the reason for missing the body parts after scaling?

I have attached the figures. Thanks for your time

I believe this may be just a visualization issue. Could you try loading the scaled model back into OpenSim and see if the bones show up again?

Hello,

Thanks for your reply. I tried loading the scaled model. It's the same. My original model has all bodies.

If any part is missing after scaling, is it a big issue or it is just visualization?

Hello,

This is a visualization issue. Scaling can not lose bodies (by construction) which you can verify by checking the navigator panel and the model tree of the scaled model. The issue boils down to resolving the geometry search path for the mesh files of the scaled model which can be resolved by saving the scaled model in the same folder as the original model and then reloading, or by changing the geometry search path preference as suggested by Carmichael.

Hope this helps,

Thanks Mr. Ayman. The problem is solved now.
