Save settings

Filename

Specifies the file to be used when saving weights. This is a simple ASCII text file for easy custom manipulation outside of Maya.

Weights

Lets you select the type of weight to save.

Save Weights

Saves weights for all points of the deformed Muscle object specified in the Node field.

Load settings

Filename

Specifies the file to be used when loading weights. Click the button to browse and select a file containing saved weights.

Weights

Sets the type of weight to load. You can save from one type and load onto another if the weight types are compatible.

Normalize

Turns on/off automatically, but you can override the value to determine whether loaded weights are normalized to 1.0 for each point. This setting has no effect on simple per-point weights.

Load By

Specifies if loading occurs by point order/index or by point position. Point position loads are slower but allow for mirroring of weights, as well as reloading onto topology that may have changed.

Point Position Match Tolerance

A value of 0 or higher sets the distance at which point position loading must match the distance from the original surface. A value of -1 means disable/ignore tolerance.

TipRight-click the Tolerance field to select a preset Tolerance value.

Prune weights to

When checked, weights that are loaded are pruned to the specified number of decimal places. The default is 3, so a weight of 0.12345 becomes 0.123.

TipRight-click the Prune decimal places field to select a preset number of decimal places.

Mirror Pos.

This is used during point position loading to mirror the loaded points. This is typically used in conjunction with the Search/Replace fields.

Search/Replace

Used with the Mirror Position option. After a matching point is found, this does a Search/Replace on each original influence so that loaded weights can be applied onto a mirrored side. For example, if a Search/Replace is set to _L and _R and a point is found to be weighted to a muscle named MuscleBicep_L, when the weight is loaded it is instead applied to MuscleBicep_R.

Select Influences from File

When a weight file is saved, it also contains information on what original bones/muscles/capsules were used. Clicking this button re-selects the original influences based on the data in the file. This option works in conjunction with Search/Replace, so it can be used not only for reselecting all influences, but for selecting mirrored influences.

Load Weights

Loads the weights from the file onto the mesh that is deformed from the specified Muscle deformer node. This works for selected points. If no points are selected, all points on the object are automatically selected and loaded. When loading weights for mirroring it is important to only select the points on the side of the object you want to load so that the original side remains intact.
