This is useful because details are only shown when the player is close enough to see them. These are interchanged as the player moves closer or further from an object. In video games it’s common to have several versions of a model. In this way we can preserve the details we get from high-resolution work, but still generate a model that runs smoothly with animation. Getting a good UV unwrap is necessary for textures and materials that comprise the surface of the final model.Īnd the best part: we can use high-polygon models to make textures for the topologized version! It’s also easier to UV unwrap a low-poly model than one with many polygons.
Through retopology we recover a more efficient 3D surface that’s better for painting and animating(either for movies or video games). The process of sculpting in tools like ZBrush or Blender results in high resolution models with many unnecessary polygons. The main use of retopology is to get a polygon mesh at a smaller file size that’s useable for animation.

The new retopologized mesh will be free of distortions and other problems that are often present in free-sculpted 3D meshes. Retopology allows artists to create organic, high-resolution models from the start using a workflow that’s much more fluid than the old box-modeling technique.Īlso if you retopologize your models it becomes easier to add textures to sculpted models. Image source by yudhi prilla The Benefits of Retopology It’s often desirable to retopologize the mesh by hand so the results can be fine-tuned. There are tools to auto-retopologize a 3D model so that’s always an option too.īut depending on the tools, and the model, you can expect varying degrees of success. Sculpting high-res models is faster and more natural so it’s much easier. It is more common to start with a high-resolution model and work backwards. Today box modeling is considered old-fashioned.
It is necessary to limit the polygon count of any 3D model when it’s used for animation. This is because complex meshes are difficult to animate. Later more details could be added, but the original mesh would be preserved for animation. The surface of a character would be approximated using the simplest forms possible. Why RetopologizeģD artists used to rely on techniques like box-modeling to create their objects. While it sounds intimidating, retopology is an important part of the sculpting workflow. By overlaying a low-polygon mesh onto a high-polygon mesh you can get something that’s perfect for animating and easy on your processor.
And too much detail will slow down even the most powerful computer. The downside is that you have to create a lot of polygons to sculpt the curves you need. Sculpting is a more intuitive process that lends itself better to how artists think and work. The problem with this approach is that it’s very technical and difficult. In the past a 3D artist would painstakingly build a mesh polygon-by-polygon. It can be a difficult process, but the basic idea is to create another mesh that simplifies the original HD asset. Retopology is the process of converting high-resolution models into something much smaller that can be used for animation.

On the video I showcase retopo, I saw now that I cut some of it, but it was around 7 to 15 seconds per object even on my not very powerful laptop. Mostly again with CAD models “auto edge” on, can have difficulties, or increase significant processing times, mostly with bad geo, try to turn it off. With long triangles (tipical from imported cad data) retopo can have problems, thats the reason we have an updated subdivide tool, (even if you increase polycounts, if the triangles are more seamless, retopo will be faster. Make use of the new meshcleaner modifier, to clean non manifold tris and other problems. Check the mesh, with cad data, comes a lot of nasty triangles. First do a prooptimize and bring your original 15M to 100K, for example, will be easier to digest for retopo. If you are working with a 15M polys scan, and your objective polycount its 10K.
