Right clicking over a thumbnail makes it the current selection and opens a Context Menu. The only option on the context menu is Copy Address. Selecting this will copy the file path of the selected thumbnails HDRI file to the Windows Clipboard. The Status Bar will update to reflect the copied path. You can then paste the file path directly into the TurboCAD Render Scene Environment Editor. This is a great time saver when creating cubical maps from within TurboCAD.
