Thanks for all the help guys really finding tricks to make my workflow convert to blender!
Some odd interactions learning the f2 addon for retopo which is rather good! but too do so need a shrink map + Mirror modifiers which upon alot of testing mirroring manually and the modifier seem to play by different rules an the shrink wrap wont even do anything too the already modified mesh, is this due too adding them later in the workflow?
An example of my old workflow.
In Maya i normally would do one side with it off then “Mirror -Z merge 0.5cm” So the faces in the center would line up perfectly.
