When it arrives to make retopology, Blender doesn’t really have much in the way of special tools built into it. A few very useful add-ons, such as outline and (or their bundled combination have been created by third-party developers to help with the retopology method, but they don’t ship with Blender by default. That said, if you find that sculpting and modeling are your preferred aspects of 3D computer graphics, you’ll be going through the retopology process a lot. In that position, investigate and eventually purchase those add-ons. But it’s still useful to know what Blender can do on its own as well. Retopology add-ons can get you part of the way there, but most of the time, you still need to finish with Blender’s native tools.

When a model is created as a polygon network using a 3 UV coordinates can be created for each peak in the grid. One way is for the 3D modeler to open the triangle grid at the joints, automatically laying out the triangles on a flat page. If the mesh is a UV sphere, for example, the modeler might transform it into a rectangular projection. A UV map can either be developed automatically by the software request, made manually by the artist, or some combination of both. Often a UV map will be developed, and then the artist will adjust and improve it to minimize seams and overlaps. If the model is balanced, the artist might overlay reverse triangles to enable painting both sides at the same time.

Dynamic topology is a vital check sculpting procedure, adds and eliminates details on-the-fly, as long as regular sculpting just effects the build of a engage.
This makes it possible to sculpt complex shapes out of a simple grating, rather than just adding details onto a modeled base lattice.
