I mostly got started by looking at the polycount wiki's subdivision page. I just learned to be more efficient with how many loops I put down and I weld extra vertices together until I get something resembling the bottom image. It also helps to use symmetry or array modifiers, so I can mirror all topology changes…
I realize I'm a little late, but I just had to share my experience. What's funny is that so far, I haven't really had any bad habits in terms of modeling. Not even in Zbrush. I skipped most of them and taught myself everything I know so far correctly from the start. Although when I started with high poly to low poly…
I used to: Model using almost only extrusions and some bevels due to fear of having bad topology, avoiding triangles and ngons like plague. Now: I use chamfers, booleans, bevels and every tool and modifier I know to break the shape, prioritizing form over topology and making my life a lot easier when unwrapping. I used to:…
