Hi everyone,  
I did a segmentation of a brain with a tumor (specifically the MRBrainTumor2 in BuiltIn). I’m having trouble with the save operation. How can I get 2 different mhd files for the two objects? In the save list there are only these objects (see photo). I have to use the two images to build a tetrahedral mesh with vmtk.  
Thanks in advance

When you export a segmentation to a labelmap then by default only the visible segments are exported. So, you can have two labelmap volumes, each containing one segment by showing one segment, export, showing the other segment, export.

For volumetric mesh generation I would recommend to use SegmentMesher extension, which can generate multimaterial tetrahedral mesh directly from segmentation.
