Geografting and Transfer Utility Geometry for Noobs Questions

I am trying to geograft an object to a G3 figure in DAZ studio. I exported in .obj, and edited the mesh by removing some verts and then filling in the exposed face on the side. Then I reimported as an obj. I am not sure if I am using the right settings to reimport. The only guide I could find about reimporting into DAZ was for dealing with morphs, and that was for dealing with something that was originally exported as a .dae and then back to .obj later... so I am wondering if that is the issue. The resulting import is coming with extra connections to the verts in the geometry that are not there in the original or in blender. I tried to run Transfer Utility anyway, and it does rig the object to the parameters of the general area where it originally came from, but it shrinks the object, not keeping it aligned to it's original geometry.
Hopefully the pictures below will explain. I am also unsure if I am proceeding correctly down the path to achieve my final result, which should be a geograft that visually removes the left arm below the shoulder and replaces it with this object's flat surface. Will I be able to extend the texture onto this object as well, or am I going down the wrong path to this goal?

Your mesh is being triangulated on export from Blender - check the export options.
Do the vertices around the edge of the graft still match the vertices on the base figure? They must be exactly the same for the graft to weld (though the hiding of unwanted polygons doesn't depend on that)..
I was able to avoid the triangulation (thanks for pointing that out Richard). However, I am still getting extra other geometry, not just the diagnal lines from triangulation, but it's as if when exported from DAZ, every face is doubled... if that makes sense. For each polygon in DAZ, it has been divided into two equal halves when imported into Blender. This is .obj to .obj, and before I have made any edits. I thought maybe that was just normal, as I am new to this, but I wonder that it might be a symptom or the cause of what is happening when importing back in? The "edge" of the group, the loop of verticies along the seam between the shoulder and the arm, is still initially lined up to the same position when it's imported in, but the newly imported object still has double the verticies than the geometry from the original source. When I run transfer utility, it shrinks it and moves it slightly toward the interior of the figure as seen in the third photo above. The triangulation is gone, but otherwise, same other issues. The object is rigged, but in the wrong place and with double the verticies as the source object exported had.
Shrinking sounds as if there was a moprh applied to the figure when exported, the doubling up sounds as if there was soemthign else in the scene, such as a Geemoetry shell or a second copy of the figure.
Hm, I am working from a fresh new file, where I have only placed a single figure and nothing else for the export, so it doesn't seem like it could be a duplicate figure unless something really buggy is going on. I am not sure what a Geometry shell is, but I have done nothing but just add the figure to the scene. There IS only one body morph applied, but rather, it is UN-applied... I do have another bug where every figure I place in the scene starts with the Tween Julie morph applied, since I have this and many products, but I just set that back to 0 since that's not what I'm trying to work with. Maybe that's the problem? I am trying to use a different figure, but no matter what figure I use (female I mean, but that's the character I'm trying to work on) it always initially starts with this morph. Is this possibly the cause? I have a ticket in to DAZ, but haven't heard back yet. Has anyone else had this issue, and know how to correct it? Maybe it's related to my issue for this thread... tried uninstalling and reinstalling, and problem persists.
That sounds as if either Tween Julie has its default value set to 1, or some other morph is set to 1 by default and is set to drive Tween Julie. Look under Currently used in the Parameters pane Editor tab - click the gear icon on Tween Julie's slider, or any other character slider that appears there, select Parameter Settings, and look at the Default Value; if tween Julie's default is non-zero simply reinstalling it should work, if it's a non-Daz morph then it may be simplest to set the default value to 0, click Accept, and then use File>Save As>Support Assets>Morph Asset to resave that morph (using the defaults in the options dialogue, which should ensure it overwrites the original version). I suspect it is a third-party morph, and that it is also applying some scaling.
Ok, this topic has morphed into a different one, however, it still seems like there might be some relationship between these issues. Maybe, not sure. When I save the Morph, it asks me to select a node or nodes. I just select the whole figure node, and then hit accept. It seems to do a lot of stuff, saving the asset... but it just saved it to "product" and nothing appears different (which I would think is good since we are trying to overwrite). However, the default is unchanged the next time I load the figure. These are not 3rd party figures, and no third party content is being used in the scene, nor have I gone in and installed any 3rd party content into folders meant for DAZ official content or messed intentionally with anything manually. This is very strange. I just load up an official content purchased from DAZ store like Victoria 7 figure or a figure based on that, and even though I saved the morph with 0% on the Julie morph, it doesn't seem to take, it's still doing it on the next time Ioad one of said figures.
I'm not sure that you were in the right place by your description of the save options.
When you load a Genesis # figure all DS format content directories are scanned for the asset folder, and all morphs are added, so having third-party content in another location won't block it. What morphs are listed in the Currently Used group in the Parameters pane?
I'm just getting started with geografting myself, but I have a couple ideas you might try.
First, I suspect the doubling of polygons is actually a quadrupaling; each polygon divided into quarters. If that's not the case, my solution probably won't work. The Genesis figures are all SubD figures, so before exporting, make sure the figure is set to "Base" instead of "High Resolution" (under Parameters > General > Mesh Resolution). That will keep it from exporting the subdivisions.
Second, you may be able to avoid the shrinking problem (assuming it is caused by some figure morphs) by checking the "Reverse Source Shape From Target" option on the Transfer Utility.
I'll be interested in knowing if any of that helps. Hope so.
Ack! I just noticed the year on these posts. Well, if it's still an issue for you, hope this helped.
