Two problems - first, the size of the V3 figure can be too much for Wings. The solution to this is to only export the bits you need - select a subset and exclude the head, hands, fingers and feet unless you really need them. These are where the majority of the problems occur. A second problem is that Wings tends to split V3 into dozens of tiny groups, so if you do get V3 into WIngs you will need to select all and combine to produce a useable figure.
