Okay so I’ve been having this issue where I have the body and head separate from eachother and when I merge them together and try my best to smooth out the crease that’s between the two it’s still a noticeable line and it doesn’t look to clean. Any ideas oh how I can merge the two subtools and get it to look well connected? Any help would be greatly appreciated! 
You didn’t say how you did it. Merging with Dynamesh might give a better result.
Merge down does not create a continous topology. Only the vertex sharing the same X,Y,Z of both subtools will be welded if the weld button is active in the merge options.
If you want to have a continuos topology you will have to create a new one and reproyect all details. You can do this by Remesh or Dynameshing.
Thanks so much! I’ll definitely be doing that. I did that and a combination of the smooth and polish brush to clean it up properly so it’s not visible anymore. I really appreciate the help.
