Copy From Meshes

The weights are copied from the other meshes bound to the same Skeleton. The weights are copied by projection. So the closer the target mesh shape matches to the source meshes shape, the better will be the weight copy results.

Copy weight from …

All recognized Weight sources are listed in the Weight Sources widget. Here you select the meshes from which your target mesh shall receive the weights.

Important: Currently only meshes can be used as weight sources when they are bound to the same Avastar Rig. You must select at least one weight source mesh before you can do a weight source copy.

Tip: You can click the white circle icons to hide meshes, but then you probably want to enable the Display hidden Sources option as well (image)

Display hidden Sources

List all bound meshes for this Armature. Hidden meshes will have their white circle icon turned off (empty circle icon).


  • You can click the circle icon to toggle the Mesh visibility.
  • You can click the select icon to toggle the Mesh selectibility.


Copy from all listed

Use all meshes displayed in the list, regardless if they are selected or not

Mesh Copy options

You have further options to specify what exactly the generator shall create for you. See below for a more detailed description

Keep empty Maps

The generator always creates all Target maps, even if they turn out to be empty. Normally you do not want to keep empty weight maps. However this option allows you to change that at will

Clear Target maps

When enabled then the weight maps are cleared from all weights before the weight generator adds new weights to them. This is ideal when you want to renew entire weight maps.

However sometimes you want to recreate the weights only for a subset of selected vertices (see next option). In that case you may want to keep the weights of the deselected vertices unchanged. In that case you will disable this option.

Smooth Weights

After generating the weights perform an additional smoothing step in order to make the mesh behave a bit smoother when animated. You need to experiment with that a bit. You may like it or not.

Selected Verts

Generate weights only for the selected vertices. This allows you to fine control for which exact parts of your meshes weights are generated or regenerated.

Note: The Clear Target Maps is disabled when you select Selected Verts option. However, all weights are erased for the vertex selection before the weights are copied over from the other meshes.



Selected Bones

Generate only for the selected Bones. This allows you to fine control for which exact parts of your Rig you want to generate or regenerate the weight maps. Please take care here when you also enabled the previous option Selected Verts, because you can easily end up with no weights at all generated when the selected bones are not close to the selected verts
