Substitute Geometry Options

Old Geometry Options

When both these options are off, your original piece of bound geometry is deleted on substitution.

Retain old geometry: When on, the original piece of bound geometry, its skeleton, and its influences are not deleted on substitution.
Move Old Geometry To A Layer: When on, the original piece of bound geometry, its skeleton, and its influences are not deleted on substitution and they are placed in a new display layer. The display layer in which the old piece of bound geometry, its skeleton, and its influences are placed is named [old geometry’s name]Shape_oldSkin.

Select one of the following options.

Disable Non-Skin Deformers: When on, disables any non-skin deformations on the original piece of bound geometry as they transfer to the new piece of geometry. To re-enable the deformations on the new piece of geometry, reset the node state for each deformer.; When off, transfers only skin deformations from the original piece of bound geometry to the new piece of geometry.
Move New Geometry To A Layer: When on, the new piece of geometry is placed in a separate display layer from that of the original piece of bound geometry on substitution. The layer in which the new piece of geometry is placed is named [old geometry’s name]Shape_newSkin.
Re-weighting Distance Tolerance: Specifies how rapidly the influence of joints on the new piece of geometry decreases with distance from each joint. The greater the Re-weighting Distance Tolerance, the more rapid the decrease in influence with distance. The lower the Re-weighting Distance Tolerance, the further the influence of each joint. This option is useful when the new piece of geometry has extra vertices that the original piece of geometry does not have, and you want to include them when re-weighting the skin.
