What options should we adjust to get more object meshes?

[hanjoonwon]

The existing mesh generation method results in a bg+fg mesh, but currently the bg is not displayed properly and my goal is to get only fg mesh as much as possible, so I modified the code to display only fg.

What options can I adjust or how can I get only the FG to come out without the surrounding stuff?
