Zbrush Retopology Class - creating a low poly head using ZRemesher
Duplicated low poly head below; orange/black dotted lines indicate the 'ZRemesher Guides Brush'.
Using symmetry mode 'X' I drew on the guides (around the eyes, mouth, nose and neck)
Setting the Target Polycount to 2 - Quad count was around 7000
Setting the Target Polycount to 1 - Quad count was around 3000
Generating 'dummy' head geometry for retopologising
Duplicate the highpoly head - rename to 'Decimated_head' > Zplugin>Decimation Master>Pre-process current (NOT ALL!)> set percentage of decimation (e.g 10%) > press Decimation Current.
Export Decimated_head subtool as an obj file
Save!!!
Preparation for retopologising in Maya
Quad Draw tool does not support the 'X' symmetry function, so we have to delete half the head, work on that and then duplicate, mirror and merge
Using the quad draw tool, to draw live 'magnetic' quads onto the head.
We deleted most of the quads around the eyes, mouth and nose, as these areas are the ones that are likely to have most deformation when it comes to animation.
Quad draw and 'CTRL' then allow for multi-cuts and additions of edge loops to create good details
