View Full Version : which route is best to take when importing maps from zbrush?

06 June 2009, 08:31 AM
I've been given mixed advice on how to do this..

i want to export displacement and normal maps from zbrush to maya

When i first saw stuff on this i was shown to follow these steps

lay out the UVs for the model
export model parts as obj
import them into zbrush
save the level1 import as a morph target
up the sub divisions and start doing zbrush stuff
once done bring back the subdivisions to level 1
switch to the morph target
create normal and displacement maps
plug normal map into the bump map connection of the material in Maya and change it from bump to tangent space normals
plug displacement map into displacement connection of the material
create an approximation node and fiddle around with the settings

however when doing this i get all sorts of weird artefacts or funny parts where the maps would get compressed despite the UVs being completely flat

it was suggested by someone that i export the morphtarget level 1 model into maya

it was also suggested that i follow these steps

export obj file to zbrush without touching the UVs
up the sub divisions
start doing zbrush stuff
bring back the subdivisions to level1 when done
create the maps
export the new level 1 model from zbrush as obj
import the new model into maya
apply the maps

which way is better?
