Polygon Grouping and other Questions

ZBrush Usage Questions
#1

Hi Guys, I’m back with more stupid questions again :stuck_out_tongue:
forgive me …

Those multi-color polygon group formed when u r using ‘Zsphere’, is what i’m refering to …

  1. True, u will get them when u go by zphere creation method.
    but if i want an imported model (obj file) to also have such a group,
    how do i ‘prepare’ it in my other software first before i import to zbrush ?
    Is it by ‘assigning different materials to different polygons’ ??
    How many methods r there ??

    Also, besides, imported objs, what about a cylinder polymesh for example.
    This is created in Zbrush, but not using zsphere, so by default, there’s no
    grouping to it. If i really need to create some customised grouping for future editing, how do i assign grouping to it ?

  2. About materials …
    Up until so far … I only know about exporting basic texture and
    displacement and normal maps. But what about materials properties ?
    What if i want to export this model to other software along with the
    materials properties i created in Zbrush too ??
    I really do not know if this can be done … further more there are
    certainly some ‘self-customed’ materials used in zbrush … how do we export them say into xsi or max.

Thank you guys millions …
ps : im not as confused anymore but still confused … hah

Shift+Ctrl to select polygons for grouping (you can let go of Ctrl to inverse selection). Go to Tool>Polygroups>Group Visible. Do this as much as needed to define the mesh to your requirements. This is not an option on Zsphere models, They must be made into a polymesh first.
About Materials, I know less than you do…sorry

Hi !
Thanks so much :slight_smile:
I didn’t notice that ‘Group visible’ button at all until u mentioned it :eek:
right under my nose …

You cannot export material (shader) into other program from zbrush. every prog use its own material methods.

what you can do is bake material effects (reflections, cavity etc) into texture and then export texture, but you know - that is not the same as material…

#5

You can also use ZBrush to generate maps that other rendering engines will use: specular, reflection, luminence, etc. I have written a tutorial about it here.

Thanks guys :slight_smile:
now i’m less confused than before haha …:lol:
