Retopology Retopology is the act of recreating existing surfaces with optimized geometry, in terms of memory usage. Also allows for topology to be fit for animation, allowing models to deform and move in a correct manner. To retopologise, we first decimate our sculpt, significantly reducing the polygon count, then export it as an FBX into Maya. In Maya, the Quad Draw Tool is utilised to create new faces over the mesh whilst retaining the shape of the model. When using the Quad Draw tool, TAB is used to extrude faces, SHIFT+LMB is used to smooth regions, CTRL+LMB creates an edge loop and you can weld vertices together by dragging them using LMB. CTRL+SHIFT+LMB deletes regions of the retopology. In areas of sharp deformation, such as the eyes, shoulders and hips, it can be useful to consider creating topology in a series of concentric circles, allowing for more detailed deformation. To demonstrate the retopology process, I have created a high-topology sculpt of an alien head. ...
