I want to make a brain. I know how to model the basic shape but I don’t know how to make all those little details… should I make a bump map or what?
Bump map, spec map, reflectivity/gloss map.
maybe this will help-> http://www.joelertola.com/tutorials/tutor_frmset.html
its done with LW and with a little help from Illustrator but I think the general idea can be applied in Blender.
Good luck with your brain…
