"Facet is too small or too narrow."

[ggalgoczi]

Trying to import a very detailed model. The sides of the facets are in the order of micrometer. I keep getting the following warning / error message and my model is not imported correctly. The SurfaceTolerance is in the order of 0.001 nm in G4 by default, so this should not be an issue.
