Ok, I’m working on a space battle scene, does anyone have any useful tips or hot keys for modeling a spaceship?
One good one is to use clipping when needed.
I imagine the Discombobulate script is the only Blender function that might be of particular interest to spaceship modelers. In Edit mode, Mesh menu -> Scripts-> Discombobulate. Use it for greeble, if you want a Star Wars-type imperial star destroyer. But why limit yourself to that trite style? I think your question is way too broad. Any of Blender’s tools is useful for making spaceships, and which you use depends on your design.
