Clothing Distortion on thin bodies (between and under breasts)
I have tools for fixing that unnatural crease between the breasts that occurs in many clothing items. These stretch the clothing fabri straight across the cleavage. I am working on a project where I have the opposite problem. The clothing item is a sprorts bra that looks natural on Genesis 8.1. When I apply certain character full body morphs the clothing distorts between and under the breast. I have been able to repeat this using thin body morph, or smaller breasts that the default G8.1F. The distortion is opposite of what my tools, fixers and helpers are designed to correct. Instead of an unnaturally deep cleavage, I have a raised triagle between the breasts, which extends about a half way under the breast. I was able to get a fairly smooth area by cranking the smoothing iterations up to 30, but then I lost the "tension wrinkles" between the breasts that made this garment so attractive.
I also tried applying a dForce Dynamic Modifier with contraction set to 99 and simulating. After plaiyng with several settings I got something close, but it did not look great.
Short of exporting the garment to OBJ, taking into Zbuish or Blender, applying a smoothing modifier, then painting (scultping) the wrinkles back in, exporting to DAZ, transfer rigging or creating a morph...(are we tired yet?) Are there any tricks people have discovered to make this better within DAZ? Again the problem is: Raised traingle in a garment, between breasts when applying thin body morph or reducing the breast size from the default G8.1F.

You may be abl;e to use a dForm to pull some areas back, using a weight map to restrict the effect. With clothing that is smooth or where the adjustment needed is slight a Push Modifier, again weight mapped, may also be useful but it moves the surface in/out, so it will tend to grow or shrink wrinkles rather than moving them along the same path as the flat areas.
Have you tried turning off limits and applying a negative value on these?
If you actually have Zbrush to use, I find you can fix a lot of those kinds of issues with the move brush set fairly large size for major moves, then set small for tweaks after that, then a really light touch with the smoothing brush after that. The move tool shouldn't mess up the fine details, the smooth brush will, so that's why you need a light hand. I am sure the sculpt tools in blender can do similar, but I have zbrush, and GoZ makes it a breeze to go back and forth.
I'm having a similar issue, but mine is with a thicker, bustier body. I'm not trying to hijack the OP's thread, so if someone wants to tell me to get out, I'll be happy to start my own. But I'm curious about what causes the issue circled in red, and if there's a way to fix it without bringing it into Blender. I tried that, but there was just too much distortion for my limited skills to be helpful. I also tried playing with the weight maps, and even went as far as removing them completely, but that didn't seem to make any difference at all.
There was another thread discussing this recently, and it's not currently an easy issue to fix.
Most (well made) clothes will have correctives for most of the breast morphs in Daz's main morph pack (e.g. https://www.daz3d.com/genesis-8-female-body-morphs for G8F, and the appropriate equivalents for other generations), so sticking to those can help a lot, but it's not perfect and the moment you start getting into unsupported PA morphs you've got a whole new pickle. While it's a port in a storm, Fit Control cannot possibly perfectly account for every possible way a vendor may have morphed a figure, so its results are varied and often tedious to reach.
I have my own method to fix distortions in the breast area - big or small - but it's complicated to set up manually (although nearly automatic once set up) and it's something I'm still trying to get automated to make it more accessible to others.
Matt, would you mind to share how you fix the breast distorsion ? I'm in need of help on a larger character...
I wish solution on breast problem also.
The method would be very impractical for others to follow without access to custom tools I'm still refinining. While I'm hoping and planning to release it to other people in future, it's currently in an alpha state that's not ready to be inflicted upon the world.
One thing you can try if you're familiar with the transfer utility - export a base obj out of your clothing item in default state, smoothing turn off. Look through your library of clothing and find one that has a similar design - bodysuit or t-shirt, and then use transfer utility to fit your obj to that clothing item (not the figure). Dial up the morph and since your morph is now following the clothing item it should have less of an issue. Export that and import as a morph into your clothing item with the problem. :)
