I have been trying to unwrap my model after following some online tutorials on this topic, in the tutorial, the instructor said that all sharp edges should be selected and then marked as seams for whatever hard surface models you are making, is what the instructor recommend right? Because right now there are tonnes of small islands as shown in the photo (mainly placed near the boundary after I unwrap the model w/ all sharp edges marked as seams)
On the other hand, what is the 'correct' workflow in packing islands to make the UV map user friendly? Should I place islands that are of the same object together in the UV map to make it more intuitive for users(for example all selected mesh of my model in photo packed together in certain area of the UV map)? Or no one cares about the positioning of these small islands actually (I plan on texturing the whole model later)?
