Houdini 20.0 Nodes Geometry nodes

Volume Splice geometry node

Splices overlapping volume primitives together.

Since 10.0

The Volume Splice operation splices overlapping volumes together. The volumes have to be axis-aligned with matching voxel sizes. This sort of output is common from distributed fluid sims.

The input primitives are grouped together by their name attribute. A new volume is created for each group large enough to contain all the source volumes. Each voxel of the new volume is copied from at most one of the source volumes. If more than one overlaps, the voxel closest to the center point of the primitive is used.


This node currently only works with standard Houdini volumes. It does not work with VDBs.
