'PosInterpol' : Unresolved object error

i have follow the instruction of “How to setup your own MoCap driven Model”,and i am facing the problem of "‘PosInterpol’ : Unresolved object ",can you tell me how to solve this problem in more detailed procedure?


This error will typically occur if you try to create a marker driver using a name which you do not have in the C3D data.

Please try this:

Exclude all markers in the markers.any file

One by one include the markers.
If you get the error again please ensure that the markername being used in the same as you have in the C3D file.

The names used in the C3D file can be seen in the modeltree as Main.ModelSetup.C3DFileData.Points.Markers

Best regards

I’ve got the same error and recognized that the marker names of the pelvis also appear in the “Mannequin.any” and not only in the “Markers.any”.

After changing the marker names in the “Mannequin.any” the model was loaded.

Maybe this info should be added to the wiki:

Not sure which one I may edit?


We would very grateful if you can contribute to the wiki.

We are in the process of moving the wiki to github, so updating it there would be the way to go.

I had to rename that particular file you were looking at since the system didn’t like ‘:’ in the filename. The new link is:
