Does CGAL support 3D meshing of multiple objects?

I would like to mesh multiple (about 25) objects all at once using CGAL. However, only one or two objects are output. Is this a bug in CGAL?

I use Gray_level_image to mesh. The range is from 1.0 to 3.0 and I use float as number type. Also, 1.0 to 2.0 is set to be in the spatial domain, 2.0 to 3.0 is the object domain, and I set 2.0 as isovalue.

In the upcoming CGAL version, there is a new example in the documentation, documented in the manual at 3.4.1 Domains From Segmented 3D Images, with a Custom Initialization. You can find the code in our Github page. That new example explains how to detect all connected components of the domain coded by the 3D image, and use a custom initialization to ensure that the initial mesh will have vertices on all connected components before the mesh refinement algorithm is launched.

That example is about a 3D segmented image (values at each voxels are integers) whereas you have a 3D gray-level image, but the method would be the same.
