Not sure if this has been posted before but I am having problems with DynaMesh. When I retopo a part of my mesh create creases for it then DynaMesh it I’m left with Like a peace of clay of a mesh instead of a mesh with better poly flow. But If i do this with a primitive in ZBrush it works fine. Am I doing some thing wrong?
I will update this post with a video of the problem. Thank you for your help in advance!
Perhaps try making a very minor adjustment to the mesh, using the project dynamesh option, or subdivide it once more first, just to give dynamesh something new to calculate?
Dynamesh (and other zbrush features) depends on the absolute scale of the tool, so if your geometry is really “small” then even very high values won’t be enough, as in your video. Unfortunately I don’t think there’s any clear “world” scale indicator in ZBrush so it can be hard to tell when your tool is “small” except for when things go wrong. What I’d do is use subtool master to merge all subtools (uncheck preserve existing subtools), then use transpose to scale up 200-300% or so, then select the merged subtool and run groups split.
Dynamesh subdivision is depending on objekt size.
The cube is much bigger than your object -> more subdivisions 
Try it out!
Take your object, scale it several times to 100 under deformations in tool palette.
Subdivision will be much higher.

Thanks you guys making it bigger did work. Where did you find this information at? Is it in the zbrush documentation?
Do you guys think that this may happen in the opposite direction? Having a trully BIG tool, bigger than “real world” scale may affect dynamesh functionality?
Thanks!
If it’s too big (way bigger than Preview window), the odds are that you will get a memory error because your machine wouldn’t be able to handle that many polygons. So, no, it doesn’t hold true in the opposite direction. I have already experienced this on my own machine. The bigger the tool, the more the resolution. See my response to your question in the thread above this one for a possible solution to your problem.
