Having trouble preserving high-res details with Dynamesh/retopology

ZBrush Usage Questions
#1

I seen in the documentation that Freeze Subdivision Levels is supposed to allow you to retopologize while keeping the high-res details, but I’m having trouble getting it to work properly.

I made a mesh from scratch with Dynamesh, and now I need UV’s, and my mesh is too high detail to create them on the high-res version…

My primary issue is that when I unfreeze a low res version I only get a small portion of the high res details back? For example if I take a 1million ActivePoints mesh and use Dynamesh then unfreeze it will get to around 100,000 ActivePoints back?

Basically I need a way to load a retopologized mesh (with UV’s) on to my high res dynamesh, not sure how to go about that properly as I can’t figure out how to get Freeze Subdivision Levels working properly by the limited documentation on it?

I can’t do reconstruct subdivision levels past 1mill activepoints at the moment either…

Any advice would be appreciated. Thanks

Usually what I do if I ever need to take my high-res DynaMesh and add UV’s later is to first duplicate the mesh. Now on the duplicated mesh I drop the DynaMesh rez all the way down so that I have a mesh with a reasonable Active Point count. Next I turn off DynaMesh and then subdivide the model back up to the same (usually more) Active Point count as the original high-res mesh, and then project the subdivided model to my DynaMesh. This effectively creates a subdivided model at the same resolution (or higher) than my DynaMesh, that has all the same detail as before, but now I can drop the subdivision levels and create UV’s.

Hope that helps.
