TGeomanager openGL small parts missing

Geometry
1

Hi all,
I am using a gdml file to check the geometry through TGeomanager.
There are a few small parts in the geometry that are missing in the openGL.
However, I can see these small parts when I make them larger by increasing the dimensions. Is there a solution for this?
Thank you.

You could try to change the Level Of Details (LOD) in the TGLViewer

TGLViewer *glViewer = dynamic_cast<TGLViewer*>(gPad->GetViewer3D());
if (glViewer) glViewer->SetLOD(16);

But @matevz or @agheata can most probably help you more on that subject
