Just a warning: The current version has performance issues, it stutters like crazy even on beefy setups. It seems they didn’t get the level streaming implementation of UE5 right on the first try. This will probably get fixed for 1.0, but currently it’s painful playing in some parts of the map.

Handheld battery powered X-ray devices exist and are widely available. I used to work with those. In Germany you need a permit to operate them. https://www.thermofisher.com/order/catalog/product/de/en/XL2
