Houdini 20.0 Nodes Geometry nodes

Labs Fast Remesh geometry node

This node performs Houdini’s native remeshing operation on partitioned geometry, processing each piece in parallel which greatly reduces the calculation time of traditional remeshing.


Parallel Processing

Partition By

Connectivity and Bucket Size will have options to partition by connectivity, UV islands, and clusters of primitives. Custom Attribute partitions geometry by a custom primitive integer attribute.


3D Connectivity

Partitions geometry based on individual connectivity.

3D and UV Connectivity

Partitions and geometry based on separate UV islands. Remeshing by connectivity is included in this option.

Bucket Size

Partitions geometry by clustering primitives.

Target Bucket Size

The target number of polygons in each cluster. A lower value will generate more clusters.

Bucket Seed

Randomize geometry clusters.

Attribute Name

The name of the custom primitive integer attribute used to partition geometry.

Visualize Partitions

Assigns a random color to each partition.


Remesh Target Type

Target Edge Length sets the target edge length directly.

Target Polycount sets the polycount goal of the output geometry.

Ratio of Average Input Edge Length sets the target edge length to be a ratio of the average input edge length.

Ratio of Input Polycount sets the polycount goal of the output geometry to be a ratio of the input geometry.

Adaptive Remeshing remeshes based on the curvature of input geometry.

Target Edge Length

Target length (in Houdini units) of resulting triangle edge lengths.

Edge Length Ratio

Ratio of the target edge length to the average input edge length. A ratio of 2 will make edge lengths twice as long.

Target Polycount

Target polycount goal for resulting mesh. Higher remesh iterations will more closely reach this goal.

Polycount Ratio

Ratio of the target polycount to the input polycount. A ratio of 2 will double the amount of polygons.


Target Edge Length Min

Minimum target edge length.

Target Edge Length Max

Maximum target edge length.


The rate at which edge lengths are allowed to change from one triangle to the next. Higher values generate fewer triangles but the overall quality is lower.

Remesh Iterations

Increasing this increases the quality of the generated mesh but takes more time. More iterations will produce triangles that are more equilateral. Increasing this parameter while performing Adaptive remeshing may cause holes in geometry.


The amount of additional smoothing to apply after remeshing.


Remesh Seams

Resulting seams can be visible in the resulting mesh, especially in adaptive remeshing. Remesh Seams only remeshes these affected areas, blending them into the whole mesh.

Fuse Remaining Seams

Fuses remaining partitions into a complete mesh.

Recompute Normals

Recalculates the normals of output geometry.
