tool> masking
Intens: The strength by which masking is removed by the Row/Col/Grd commands. Use different Sel/Skp settings with different Int amounts to vary masking strength on different parts of the object. Default is 100%. Range is 0% to 100%.
Blend: The degree to which a new masking operation mixes with an existing mask. This lets you, for instance, combine a Row/Col/Grd mask with an Alpha mask. To use, create a mask, then set the Blend amount, and then apply a second mask, and so on.
Intens: Blend: how to use it ?:rolleyes:
