Retopologises the parent mesh
Retopologise
Method #
This node generates a Signed Distance Field representing original mesh, then samples it using a Marching Cubes algorithm. The resulting mesh maintains the general shape of the original, but with a more consistent polygon density and a simplified shape. This process removes UVs and weight maps, while colours are resampled along with the vertices. UVs may optionally be resampled onto the new mesh using the “Retain UVs” option, but the retopologisation will introduce new discontinuities in the UVs.
This node is useful for reducing polygon counts of very dense meshes for use in other processes such as particle emission or collisions or to regularise the topology of a mesh for further deformation.
Parameters
These properties control the core behaviours of the node.
Parameter Details Resolution
The voxel density used to genereate the new mesh. Higher values will generate more geometry, more closely matching the original mesh.
Inflate
Offsets the surface from the original mesh, useful for softening complex areas or removing erroenous geometry.
Resample Vertices
If enabled, the vertices of the new mesh are resampled to lie exactly on the surface of the old mesh. this may introduce errors and artefacts in the new topology but provides a closer visual fit to the original mesh.
Retain UVs
Generates extra vertices along the uvs of the mesh, to maintain consistency in the UVs.
