I was wondering if people use dynameshed models with sculpted detail and poly paint as their high poly? or do they usually just bring in evenly distributed polys on a model into zbrush and increase the subdivision.
I would say 95% of the time I use Dyanmeshed meshes to bake and retopo with. Sometimes I Decimate it sometimes I dont. Sometimes I just knock down the Dynamesh res and just use that as my bake/retopo.
Its all polygons and vertices in the end. Sometimes its quicker to make a model with dynamesh. Sometimes you have an existing basemesh that works well enough on its own, sometimes you have to create one. (You can replace 'quicker' with 'better' too; when revisions are involved it can be easier to have lighter geometry)
