Introduction to Retopology

Introduction to Retopology

As modern workflows have incorporated more sculpting, the previous techniques of box-modeling and poly-modeling have seen less use. In place of these older workflows is a new synergy between artistically-driven sculpting and technically-minded poly-modeling, through a process known as Retopology.

Introduction

Fundamentals of Topology

Before learning about retopology we first need to brush up on our topology knowledge.

Visualizing Retopology

Before starting retopology it's a good idea to tweak Blender's shading display options, improving your workflow.

Retopology Methods

There are many ways to retopologize an object in Blender, let's learn the essential ones, building the foundation of any workflow.

Retopology in Practice

Let's take what you've learned and apply it to a real, sculpted object, retopologizing it with clean mesh flow.

Putting Your Skills to the Test

Nothing compares to real practice; let's put your new knowledge to the test and retopologize a complex, sculpted model.

As modern workflows have incorporated more sculpting, the previous techniques of box-modeling and poly-modeling have seen less use. In place of these older workflows is a new synergy between artistically-driven sculpting and technically-minded poly-modeling, through a process known as Retopology.

Retopology is the act of recreating an existing surface with more optimal geometry. A common use-case is creating a clean, quad-based mesh for animation, but it’s also used for most any final object that needs textured, animated, or otherwise manipulated in a way that sculpted meshes are not conducive to.

    As I was working on the exercise I found precise selection of vertices and edges difficult (I often end up selecting vertices on the back of the object if the surface is incomplete). Is there a setting to hide those or do I have to use h or alt-b? Backface culling does not really work when Hidden wire and X-ray are on.

    Can retopology be used on a ground setting as well? Like an open field for example with a lot of geometry? Or is it really meant for characters? My goal is to make a field of grass, apply the particle system, then reduce the geometry of the bumpy ground.

    what is retopology final form should be? i recently bought retopoflow (contours & polystrips) but still have no idea what is the final form should be like

      i mean should i resculpting again cos retopology result has only the basic shape of my model..what about the detail of our model like crease, etc ?

      • Hey baiaqi, the final form of your retopology depends on a few things, but most prominently it depends on your specific needs and the shape its self. In other words, if you’re creating a game model your requirements may be less than that of a film model. There is no one answer, the ideal result depends entirely on your specific needs.

        I realize this isn’t a very helpful answer, but it depends</em.

        Since you're unsure I'd suggest starting a thread in the Community Forums and asking for input and guidance there; just be sure to include screenshots of your current High and Low-res models, along with details of what the model is for.

    The download file is the correct one for “Adapting Mesh Display for Retopology” but the download file is labeled “02_03_shading-options” (?)

      That’s correct; my numbering got off as I originally had a couple other lessons to further compliment that chapter. These lessons may yet get added, but are not necessary for the course.

    Quick question, but where can I find the model file?
