Hi,
I found an issue with blender. Our packaged version it's not able to run the
Voxel Remesher, I think because OpenVBD[^1] is not included in our package.
Every time I use the Voxel Remesh tool it says:
"Voxel remesher failed to create mesh"
But the Quadriflow remesher works fine.
I searched a little bit in the code and I found the following:
Here is where the error message appears (object_remesh.c:147):
``` c
new_mesh = BKE_mesh_remesh_voxel_to_mesh_nomain(
mesh, mesh->remesh_voxel_size, mesh->remesh_voxel_adaptivity, isovalue);
if (!new_mesh) {
BKE_report(op->reports, RPT_ERROR, "Voxel remesher failed to create mesh");
return OPERATOR_CANCELLED;
}
```
So it means the `new_mesh` is not created. Checking the definition of the
`BKE_mesh_remesh_voxel_to_mesh_nomain` function we get this
(mesh_remesh_voxel.c:296):
``` c
Mesh *BKE_mesh_remesh_voxel_to_mesh_nomain(Mesh *mesh,
float voxel_size,
float adaptivity,
float isovalue)
{
Mesh *new_mesh = NULL;
#ifdef WITH_OPENVDB
struct OpenVDBLevelSet *level_set;
struct OpenVDBTransform *xform = OpenVDBTransform_create();
OpenVDBTransform_create_linear_transform(xform, (double)voxel_size);
level_set = BKE_mesh_remesh_voxel_ovdb_mesh_to_level_set_create(mesh, xform);
new_mesh = BKE_mesh_remesh_voxel_ovdb_volume_to_mesh_nomain(
level_set, (double)isovalue, (double)adaptivity, false);
OpenVDBLevelSet_free(level_set);
OpenVDBTransform_free(xform);
#else
UNUSED_VARS(mesh, voxel_size, adaptivity, isovalue);
#endif
return new_mesh;
}
```
I also checked blender package and I doesn't look like it includes OpenVDB, so
this makes sense.
As this is a powerful tool and enables much better workflows for sculpting I
think we should add it.
I'll try to add it myself, if you are ok with that.
Best,
Ekaitz
