Hi,
my problem is that I’d like to render the detector with RayTracer(X) since OGL produces this kind of artifacts. These artifacts are not visible in the OGL image posted above, but become visible when incrteasing the zoom level to very high values.
“Garbage” was not relative to the OGL image but to the RayTracer one, which is a flat gray field. But I understand that it could be the outcome of the geometry being a tessellated solid imported from GDML, right? I didn’t imagine RayTracer had problems with that since I read that it “can render any geometry that Geant4 can handle” (see this presentation, slide 60).
