Hi all,

Do you know how to highlight the lung? I was able to find some sort of preset setting that I really liked on the left panel, but I haven’t been able to find it since.

Thanks!

I would recommend to use [LungCTAnalyzer extension](https://github.com/rbumm/SlicerLungCTAnalyzer) to visualize the lungs.
