How to mask + clean Extrude

ZBrush Usage Questions
#1

Hi Guys,
I’m having trouble doing a mask + clean Extrusion in Zbrush. I’m using Deformation-> Inflate or sometimes using Ctrl + Transpose Move Tool but at the end the result is the same :frowning: It has sharp/rough ridges around the mask like this:

I saw many people did beautiful engravement on their design and stuff. Something like this:

I understand that we need to increase the subDiv to a higher level then perform the mask + Deformation-> Inflate will eliminate the sharp/rough ridges.

But is there a way to achieve this without going through higher subDiv level ? Because if we keep increasing all the objects/parts in our character, the polycount would be ridiculously high right ? Or what method you guys usually do ?

Thank you very much :slight_smile:

People generally create fine detail at high degrees of subdivision, then capture that detail in the form of normal or displacement maps for use in external applications. So yes, you’d need to subdivide quite a bit to get clean detail for what you’re doing, but in the end you’d create a normal map to be applied to a low poly version of that object in another app.

However, you can make use of the slicing tools to slice clean lines into geometry, then Transpose-extrude the resulting polygroup shapes. If done correctly, this should result in a very clean extrusion even at low poly. This is only really suitable for simple shapes.

the other way could be make polygroups from polypainting…

Another possibility is to make with hardsurface-techniques self the shape clean and as low-poly first (depend on your complexity of your final shape that you want have finally.)
Then you can crease the surfaces of this low-poly result and later divide this shape and see what you can more do with your work or what not: Polish and or give polygroups, or transform in Dynamesh-Highresolution and work more on it, ect…):
