You have an auto generated clothing morph that needs to be adjusted or fixed, and you want to replace it with a modified morph. We will outline the steps to complete this fix.
Using a clothing item, like a cap as an example. When you dial the child morph the brim gets warped and broken. You aren't happy with this morph and need to replace it with a fixed version.
You can either fix the morph in your modeler or save the smoothed version and use that as your morph. When you reload the new morph into DAZ Studio with Morph Loader Pro..., use the Overwrite Existing: Deltas Only option and it will replace the old broken morph that studio generated with your fixed morph. Here's the workflow broken down into steps:
In studio, scale the child up to 100 percent (this is necessary to get the cap to scale correctly with the child morph).
There are two options here:
Using Morph Loader Pro, import in your fixed morph target, using the Overwrite Existing deltas only option. This will replace the broken auto generated morph with the fixed version.
Test the morph, and make sure the problem is resolved (sometimes you have to spin the child morph dial on the figure to reset the morphs and see the changes).
Save your new fixed morph target, by either re-saving the cap again as a .dsf file, or you can choose just to save the child morph target out as a DSF morph file (which is the preferred method).
Tip: Always work on the different character shapes with their scaling set to 100 percent. Your morph will develop scaling issues if you work on a character that has scaling set to anything but 100 percent.
