I have the following problem. I modeled slightly open mouth. When I click re-Dynamesh the mouth stitched. Even if I set Resolution = 2048. What is the solution?
There exist not a solution.
Dynamesh will always refresh the mesh to distribute the mesh.
Only what you can do is, to active the Re(Projected) button on Dynamesh.
But that help also not so much.
But you have to do anyway later a ProjectAll process (duplicate your Model and project with that ProjectAll function,the details, step by step). For receive a divide levels Model.
For that, learn to work with that process: ProjectAll.
Search in YouTube or so, for that ProjectAll process/detail transmission.
Sorry for my english.
If it helps what I do is use the move tool to move the edges of the mouth far enough away from each other so that the Dynamesh won’t consider it to be a whole within the mesh caused by a sculpting/modeling error. Then move them back into a satisfactory position.
OR my more recent preference is to make a SubTool clone of the current model (to retain any current high-res detail, if any exists), and then with either the clone or original, doesn’t really matter, you can use Zremesher to significantly reduce the polygon count and redistribute the polygons evenly across the mesh. In most cases, especially when the mesh you’re working is already made of purely quads, this should be enough to make everything neat and tidy without have to resort with Dynamesh, and I’ve encountered one experience when Zremesher stitched any unintentional pieces of my mesh together. However, in the case in which that fails to get exactly what you what, after having used Zremesher (my go to settings are “Adaptive” with the number set to between 20-100, depending on complexity), you’ll want then want to use Dynamesh at 2048 and there’s some space between the lips, you should be able to get away with them not stitching together.
Hope this helps!
you can also try making the surface of the lips separate poly groups and dynamesh with groups turned on.
