I would like to work on this issue

Assigned! Its probably an issue in vtkF3DMetaImporter:245

Some minor update on the topic, since some time passed. Unfortunately, I didn't have much time last week and only worked a bit on it. But so far I didn't find any obvious to me issues in regard VTK state related to this issue (VTK-level visibility seems okish). So I am trying to track how visibility is tracked down directly to shaders/drawing as I do not understand why they are visible/invisible in a way they are.

Hum, I'd have expected this to be more straitgorward, I can take a look if you want.

Maybe give me just a little bit more time. In general I am still exploring VTK and 3D graphics.

I got a bit sidetracked focusing on visibility, but the real issue was that all actors were being rendered in the same position—not just one being visible. You were right about the location in the code; it was in the constructor called at this line. I'll create a merge request soon.

Damn, I should have thought of that!
