The Isotropic Remesh operation results in a uniform polygon distribution across the topology. This is useful for when the topology of a mesh is used for complex calculations such as for soft-bodies, simulations, and animations.
To perform an Isotropic Remesh operation in InstaLOD Studio, choose Isotropic Remesh from the Mesh Operations menu at the top of the Mesh Operation Settings panel.
¶ Settings
The following overviews the mesh operation's settings:
- Edge Mode: Determines the method used when calculating the length of the edge.
- Target Edge Size: Determines the length of the generated edges based on the chosen
Edge Mode. Increasing the size will increase the length of each edge. - Precision: How many refinement iterations to execute. More iterations results in a higher degree of isotropy. A higher precision setting will increase processing time.
- Welding Threshold: Welds vertices based the chosen distance threshold. This is done as a pre-pass before the operation occurs. Welding vertices can be used to close holes on the input mesh.
- Geometric Feature Angle In Degrees: Preserves the geometric features of the input mesh based on the chosen dihedral angle. Feature angles above the threshold will be preserved.
- Collapse Threshold: Collapses edges based on the
Target Edge Sizein favor of preserving geometric features over isotropy. Lowering the percentage will preserve smaller geometric details.

Collapse Thresholdsetting, please read the following article: Preserving Mesh Details with Isotropic Remesh.
¶ Feature Preservation
These settings determine which features of the input mesh to preserve when running the Isotropic Remesh operation.
- Preserve Color Splits: Preserves the color splits of the input mesh.
- Preserve UV Splits: Preserves the UV splits of the input mesh.
- Preserve Normal Splits: Preserves the normal splits of the input mesh.
- Preserve Volume: Preserves the volume of the input mesh.
¶ Normal Recalculation
- Recalculate Normals: Recalculates the normals of the output mesh using the specified
Hard Angle Threshold. - Hard Angle Threshold: When recalculating normals, polygons are smooth when their normals are under the threshold in degrees.
¶ Advanced
- Deterministic Execution: Makes the algorithm deterministic at the cost of speed.
¶ Edge Mode and Target Edge Size
The following table shows how the Edge Mode and Target Edge Size settings work together:
| Edge Mode | Target Edge Size |
|---|---|
| Automatic | Scales the automatically calculated target edge size. |
| Absolute | A precise value for the target edge size. |
| BoundingSphereRelative | A relative size based on the bounding sphere radius of the input mesh. |
