Hi Burr, could you maybe describe a bit what you mean by "bulge location" ?

The way Blend works, there's basically a kind of bulging happening at every single location along the blend, the bulge factor controls whether you want something that's kind of taut like this:



Or whether the blend shape bulges out more from its connecting edges like this:



But that kind of shaping is something that comes into play at every single connection point between the 2 edges, it's not like there is just 1 single point where there is a bulge, it's part of how every connection is made between the edges being blended.
