Delta Mush

Smooths the mesh while retaining detail based on a relaxed default pose.

Use the Delta Mush operator to filter deformation artifacts and create smoothing effects. The Delta Mush operator provides vertex data .

Delta Mush Parameters rollout

Relax group

Strength
Controls how far vertices move during each smoothing operation.
Iterations
Sets how many times to repeat the smoothing process.
Pin Borders toggle
When enabled, pins boundary vertices to their current position so they do not move during smoothing. This option is particularly useful when working with multiple objects, or multiple elements within a single object, that share open edges.

Mask group

Mask with Vertex Colors toggle
Masks off areas of an object using a vertex color.
This setting is useful for controlling the strength of the Delta Mush, specifically to preserve detail on smaller features.
Map Channel
Sets the map channel assigned to the selected vertex color.

Rest Pose group

Capture Rest Pose button
Sets a default, neutral pose for the purposes of calculating smoothing operations.

Deform group

Deform menu
Specifies the current deformation: either Relaxed Base Mesh, Relaxed, or Relaxed Delta.
