Hard Aurface Modeling Questions of a NOOB

[Psyk0]

I'm assuming you mean..."when i subdivide my mesh in zbrush it turns to a smooth surface instead of remaining hard edged"

If so then you need to add support edges (selected in red below) the outpout of the subdivided mesh will be hard edged as shown with the green check mark.

You could also try the crease option in zbrush before subdividing, see if that helps.

Another option would be to assign smoothing groups to your mesh and tick the "use smoothing groups" within the subdmodifier, collapse the mesh and export that to zbrush, the draw back of course is you lost your low poly cage.

Thank you for the reply Psyk0 !

Yes that exactly what I mean, when you subdivide an object at ZBrush its like doing a Turbosmooth modifier in 3Dsmax…

You have to have a lot of geometry close to the edjes to hold up its detail and retain its sharp edge (as you show in your example) ….

Isn’t there an option to add this geometry automatically without having to connect and weld a ton of vertesies….

I mean is there a way to automatically subdivide my odject and increasing its polygons, but without smoothing it at all?

Yes, like i said earlier...

You could also try the crease option in zbrush before subdividing, see if that helps.

Another option would be to assign smoothing groups to your mesh and tick the "use smoothing groups" within the subdmodifier, collapse the mesh and export that to zbrush, the draw back of course is you lost your low poly cage.

If you need more precision i'll make a quick how-to.

Simply deactivate the "Subdivide Smooth Modifier" in ZBrush before subdividing the model ("Smt" button in the Tool -> Geometry menu).

You should add some additional edge loops to your model though before you import it into ZBrush. Make sure all polygons are as equilateral as possible (have 4 edges of equal length). Avoid elongate/ drawn-out polygons. You will not be able to sculpt on those without producing unwanted artifacts.
