I see this option is available via the "kabob" menu. Some color overlay shows up, but not in the right place.

For comparison, same study in OHIF v2

Yes, I had moved the layering button into the menu for future functionality.

The segmentation alignment issue is being investigated and will hopefully be addressed soon.
