ZRemesher will recreate a new polygonal structure for your model, with a controlled flow of polygons and a global polycount value. In seconds you can convert a 200,000 polygon DynaMesh to a 10,000 poly retopologized model with a natural flow of polygons.
The fully automatic solution will give very good results for most of your needs but there will be times when you want more control. For that reason, ZRemesher can control local polygon directions by drawing control curves on your original model to drive its polygon flow and edge loops.
ZRemesher can be found in the Tool > Geometry sub-palette. It requires a PolyMesh3D object such as an imported mesh, DynaMesh or ZSphere adaptive skin. If you wish to use it on a parametric primitive you will need to first use the Make PolyMesh 3D feature. If your model is a ZSphere or a ZSketch in preview mode, you must first create an adaptive or unified skin before you can use ZRemesher.
The process for using ZRemesher is to select the subtool you would like to remesh, set a target polycount (say 20,000), and then click.
DynaMesh maintains the uniform resolution and polygon distribution of your mesh.
