I’m trying to dynamesh a portion of a model so I can better smooth out that specific area. But I’m left with this result how can I better accomplish this.
Hello @APersistant-Beginner
You can partially Dynamesh by hiding all but the polygons you want to Dynamesh, and performing a Dynamesh.
However, when you partially Dynamesh, you’ll be left with ugly geometry where the Dynamesh geometry meets any other geometry. Furthermore, that localized geometry is just going to be changed the next time you do a full Dynamesh. In most cases, it would be better to Dynamesh the entire thing as one.
If you want specific topology in one location on a mesh, this is something that would be better done when you are establishing export quality topology on your mesh and dont expect it to change again. ZRemsher has more options for partial-remeshing and produces somewhat better results than Dynamesh.
I tried partial-remeshing / freeze borders but it didn’t give the result I needed. So I went ahead and just did a full dynamesh of the entire thing & these artifacts popped up. Using close holes only increases the amount. I figured increasing the dynamesh resolution to max would get rid of it but it doesnt. What do I do?
I was actually concerned about this from your screenshot, but I was distracted by the thread topic. 
Dynamesh doesn’t work with meshes that are overly thin or 2D. Until you fix those areas and give them a bit more thickness, the problem will become worse as you Dynamesh, until the entire mesh eventually disintegrates (really!).
Try Ctrl-Z to the point from before you Dynameshed, then use the inflate brush to add a little more volume or thickness to the problem areas. Giving the inflate brush a low ZIntensity will make it more forgiving, and easier to gradually build up volume. Turning on Brush> Automasking> Backface masking may make it easier to work on two surfaces that are very close to each other.
This is assuming the mesh in those areas isn’t actually 2d. This doesn’t appear to be the case from the screenshot, but if it is you will need to extrude a bit of thickness to your geometry.
