Be careful counting on the softening brush to fix you problem. I haven;t used Hex in years but if I remember correctly the softening brush is very similar (if not exactly) like the smoothing tool in Argile. If the joint is jumbled up as much as you imply I've found that simple smoothing can actually work against you. What I;ve found makes fixing these problems is a technique that wasn;t reasonable from a time perspective until Morph loader came out. Now how I work on these problems is in increments.

I move the joint into a partial pose, say just to the point where the mesh really starts to distort, but before it becomes too distorted to work with readily. Export and "repair" the joint in your modeling program. THen use morph loader to import the morph to the clothing.

Now morph the joint further but leave the new morph set at 1, this will typically cause the joint to further distort but again not as much (the new morph is sort of a half fix). When the bending again gets to the point of being distorted but before it becomes too distorted to work effectively with, again export it and the newly posed figure and make another correction.

Repeat this as needed. When  you have the joint fully posed and a morph you like you can edit the CR2 removing the incremental morphs and creating a JCM out of the final morph.

Like I said, before morph loader this would have been days or weeks of work, now I've got it down to hours to do this.

An added bonus is that some of the incremental morphs can be used in conjunction with each other to create the appearance of a JCM that, for example creates a Bulge at one point during the joint bend, but then reduces the bulge as the joint is bent further. These "compound", if you will, JCMs are something I'm experimenting with now. It;s not fully worked out but if you want to experim, some useful info I used to make these type of morphs work together can be found here, in a thread by lesbently.
