Weights

Updated: 30 Oct 2024

These nodes control where other deformers are effective using per vertex or per polygon weightmaps. These can be connected to any Generated Weightmap input, to focus the areas the deformer affects the geometry. Some nodes, such as the Particle Mesh Emitter, can also use a weightmap to affect their how they use the geometry, such as spawning more particles in weighted areas.

You can preview the weightmaps effet on the mesh using the preview weightmap option in the Property Editor.
Weightmaps, like all other nodes in Notch, are processed based on their position in the Nodegraph. So make sure to place your weightmap nodes above the deformers they will apply to, and be mindful of the deformer stack you are creating.
