Zbrush- Generate normal map without projecting details ?
polycounter lvl 7
Hello polycount, I have a question, and I can't find an answer anywhere !
So, my question is, is it possible to generate normal maps from Zbrush, without going through the painful reprojection phase ?
In my usual workflow, I do my high poly in Zbrush, retopo in Max or another program, and then use Xnormal to generate my maps (and it does a very very nice job); but, for some reason I need to do it within Zbrush.
So the method would be to import the low poly > subdivide it > use "Project All" to get the detail from the high poly back onto the subdivided retopologized mesh, and generate the normal map...
But I find the projection in Zbrush really clumsy -but maybe that just me-, I often get a lot of ugly artifacts and even after playing with the cage, the parameters, and the ZProject brush, I can't get as good results as with Xnormal (I guess even 3Ds max render to texture would work better)...:poly127: My main concern is that I loose a LOT of time in the process
(One thing to mention, is that I'm working with pretty low resolution meshes for my low-polys (Something like 400 triangles)
So could I just have my high poly and low poly as separate subtools and generate a normal map?
(Sorry for the mistakes, and sorry if the question has already been asked
)

Pretty interesting, but I'm not sure that a final anwser, I'll keep looking, I mean, this is a pretty important feature to have, isn't it ? oO
