So in the first image, certain meshes are somehow “instanced” so that editing one mesh affects the others. Anybody know how this is done?
Then, the view mode is changed to isolate one of them and he is able to free draw boxes to select an area (as well as the back faces) and extrude etc. Totally lost here as well.
Finally, when exiting this isolated view mode, all his edits have applied to all connected meshes.
If anyone has the time to explain these steps to me I would be incredibly grateful!
