I have joined this hand with the main body with a Boolean Union modifier. However, the union has produced some mesh imperfection along the joined lines as you can see in the second photo.
The joined line in between the mesh seems to be quite fuzzy and the only way I can find to partially correct it is with a creese and smooth brush in sculpting mode. The result is never totally smooth.
Is there a better way to do it?
Here is a pics of the mesh as requested.
