problem when exporting trained marker set to bvh

[vaserchi]

Hello,
I am trying to export into bvh a file that contains a trained marker set with relative bones and bones chains. After solving the asset, I tried to export it into a format containing the skeleton information. I could export into fbx, but not into bvh format. I am not sure what the problem might be: the pop-up window for the bhv export gets displayed and stays on the screen for very little time; no file is exported. I get no errors. Has anyone already experienced a similar problem ? Maybe I am doing something wrong when defining the bones relationships. How could I get more information on the error (if any)? I tried already to have a look at the error log interface, but it is empty

Thank you
Valeria

Hi Valeria,

This issue you’re facing — the BVH export pop-up flashing quickly and no file being saved, with no error messages — is indeed frustrating and not uncommon in workflows involving marker-based skeleton solving.

Hi Valeria,
yes, I've seen similar issues before—BVH export can silently fail if the skeleton isn’t fully hierarchical or properly mapped. Double-check that all bones are correctly parented and that there's a single root. Also, try exporting from a simplified version of your rig to isolate the issue.

For more details, enable verbose logging (if available) or check if there’s a console output during export. Sometimes, re-validating the skeleton structure helps too.

Good luck!

What helped me was baking the animation to a basic skeleton first, like the default HumanIK or something super clean, and then exporting that. Also, try collapsing constraints and making sure there are no hidden or non-deforming bones messing things up. The exporter can be finicky and won’t always throw proper errors, so even if the log is empty, something under the hood might still be breaking it.
