When i started rigging in Maya, i found the way of weighting, using mainly painting tools, a little weird in some cases. It was quite annoying to weight some vertices in fast and accurate way. So i decided to develop a tool that emulates the weigting tool that is available in 3D Studio Max.
Using this tool, it is quite easy to set, scale, add or substract a small amount of influences from a pool of vertices with just a couple of mouse clicks. I found it astonishingly fast weighting fingers, lips, eyelids, and generally, places where i want the weight to be decreasing following loops or rings.
It has been developed using Python and PySide with custom Widgets ( for every row in the list of joint influences ). I have also added the possibility of Live Update the scene while user modifies influences using sliders shown in the picture, thought this option might become slow depending on the number of vertices being modified.
Anyone interested in using it, just give me a little whistle!!
