problem about custom seq

[michaelz9436]

Thank you for your work.
when I trained the pre-packed data hold_bottle1, everything is okay without errors and the result is acceptable.
but when I export the images in hold_bottle1 to follow steps in custom.md to create own data to train, the following problem happened:

Exported canonical to ./logs/9ff31eb9c/mesh_cano/mesh_cano_right_step_2800.obj
2025-06-12 10:20:27.884 | ERROR | src.hold.hold:meshing_cano:166 - Failed to mesh out object
Exported canonical to ./logs/9ff31eb9c/mesh_cano/mesh_cano_right_step_misc.obj
2025-06-12 10:20:28.497 | ERROR | src.hold.hold:meshing_cano:166 - Failed to mesh out object

I checked hand-obj alignment and it seems okay. Why does this happen and what does it suggest?
Also I'm wondering if you generated the packed data strictly the same as the instructions in custom.md.
Thank you for your time.

This happens usually when your object failed to learn any geometry. This is usually caused by incorrect data preprocessing.

Or you run marching cube on an incorrect volume where there is no density.
