Bmesh is the Blender's new modeling system. It's core feature is n-gons support, which allows us to use polygons with more than 4 sides. In this introduction tutorial we'll talk a little about Bmesh, it's benefits, and see the new tools that take advantage of the n-gons for now: the new knife tool, dissolve, inset... and finally, we'll take a look to Mesh Lint, an add-on that checks our mesh and spots triangles, n-gons and errors for us, so we're able to solve them, and deliver a techinically perfect topology in the final model :)
When we sculpt an object, is easier to increase the mesh resolution, and only care about shapes. That's why retopo exists, it's a technique that allows us to take that sculpted object, and "recreate" it with the desired topology, once we already have the shapes. On this tutorial, we'll see how to do it.
This time, we're going to use the techniques learned on the previous tutorial for modelling at least actual objects. Just basic shapes, but you'll get the idea so you will be able to create more complex models.
