Ретопологія – Retopology
Retopology is the process of simplifying the topology of a mesh to make it cleaner and easier to work with. Retopology is need for mangled topology resulting from sculpting or generated topology, for example from a 3D scan. Meshes often need to be retopologized if the mesh is going to be deformed in some way. Deformations can include rigging or physics simulations such as cloth or soft body. Retopology can be done by hand by manipulating geometry in Edit Mode or through automated methods.

Remeshing is a technique that automatically rebuilds the geometry with a more uniform topology. Remeshing can either add or remove the amount of topology depending on a defined resolution. This technique is especially useful for sculpting, to generate better topology after blocking out the initial shape.

Voxel – Воксель
The Voxel Remesher uses OpenVDB to generate a new manifold mesh from the current geometry. It produces a mesh with perfectly even distributed topology and it does not have any performance penalty once the new mesh is calculated. This makes the voxel remesher great for sculpting as it is possible to sculpt at a much higher level of detail than using other features like dyntopo which often adds more performance overhead.
- Розмір Вокселя – Voxel Size
The resolution or the amount of detail the remeshed mesh will have. The value is used to define the size, in object space, of the Voxel. These voxels are assembled around the mesh and are used to determine the new geometry. For example a value of 0.5 m will create topological patches that are about 0.5 m (assuming Preserve Volume is enabled). Lower values preserve finer details but will result in a mesh with a much more dense topology.
- Адаптивність – Adaptivity
Reduces the final face count by simplifying geometry where detail is not needed. This introduce triangulation to faces that do not need as much detail. Note, an Adaptivity value greater than zero disables Fix Poles.
- Виправити Полюси – Fix Poles
Tries to produce less Poles at the cost of some performance to produce a better topological flow.
- Preserve
- Volume – Об’єм
Tells the algorithm to try to preserve the original volume of the mesh. Enabling this could make the operator slower depending on the complexity of the mesh.

Reprojects Face Sets onto the new mesh.
- Color Attributes
Reprojects the Color Attributes onto the new mesh.
- Воксельна Перебудова – Voxel Remesh
Performs the remeshing operation to create a new manifold mesh based on the volume of the current mesh. Performing this will lose all mesh object data layers associated with the original mesh.
Quad – Чотирибічник
The Quad remesh uses the Quadriflow algorithm to create a Quad based mesh with few poles and edge loops following the curvature of the surface. This method is relatively slow but generates a higher quality output for final topology.
