Please check out this model, I can't generate Full Body data for it

[spikebor]

Could reproduce the issue by adding a root bone to the skeleton in the blueprint editor, then clicking generate.

The issue happens because most bones in your Slime character are far outside of the mesh, and the sampler fails to assign a particle to voxels in the voxelized mesh because they're very far from the voxel mesh bounds.

This can be prevented by performing a bounds check, with no ill effects. Please find attached a patched version of ObiSoftbodySurfaceBlueprint.cs.

let me know how it goes,

kind regards,

Yes I did have a root bone set.
The patch you sent does fixed the issue, thank you!
Btw the character Full Body Soft Body and the Obi Bone is somewhat having the same functionality, that is letting character does 2-ways contact with the environment colliders.
If you have to choose for your project, what is your go-to solution?
