OpenSim Scale Issue

I need to scale my data on a Full Body Model. I found this Adjusted ULB Model which works on OpenSim 3.3 version.

When I try to scale the model on my laptop (Windows 64 bit), the scaling doesn't happen well (screenshot attached).

But when I scale the same data on the same model on a Desktop (Windows 64-bit), the scaling seem to be fine but the model appears distorted once the RRA is done. I'm unable to figure out what the problem must be.

Hello,

My recollection is that this was an issue with visualization rather than scaling due to the fact that the model uses custom geometry/mesh files that the scaled model can't find. If you save the scaled model in the same folder as the original/pre-scale model and reopen it, it will display correctly. I remember this issue was fixed in the 4.0 code base so the problem should be fixed in the latest 4.4+ distributions. Please let us know otherwise.

Best regards,
-Ayman
