Zbrush offset?

Jonas Ronnegard

Hi this might seem stupid, but up until now i have only done some touch up on assets using zbrush, so i havent really done anything tiling.

So here is my question, Is there anyway to start from a plane in zbrush, sculpting for example a rock surface, and get it tiling inside of zbrush without having to edit the maps in photoshop. is there a zbrush offset?

cryrid

The entire document can be offset interactively with ~

If you're just sculpting a plane though and want to stay in edit mode, you'd probably be better off turning on wrap mode (Brush>> Curve)

sorry understand now, thanks

been trying the wrap mode out now, works great except i still get a seam is this something i can do something about inside zbrush?

bugo

try painting only in the middle, you cant paint in the lines even using ~
Or you will get a seam

cryrid

If its a planar mesh, you may have to go into Transform>> Modifiers and limit the axis when sculpting along the edges. Then it will only push it up, instead of up and out.

I'm late with the edit, but here's an example anyway:

The axis in question for the modifier (and sym) may depend if your sculpting along the top & bottom or the sides, and symmetry is really only valid if you're aiming for a symmetrical wrap.

bugo: Then what would be the meaning of using wrap?

cryrid: thats true, that explains it, thanks

Orb

Yeah cryrid method works nice,

i'm using personally the wrapmode at 2 instead of 1, with a plane that have a bit more surface around it. It's just an other way to achieve it.

i might not have understood everything correctly but with the Z axis checked it no longer goes beyond its original size, problem now is that i cant use box alpha for my brushes , any way to work around this?

Jonas Ronnegard

orb: if use wrap mode 2 then i would still have to limit axis right?

Computron

Orb, that's clever! What if I want to displace my mesh with a CrazyBump Height map first, is there any way to tile that inside of zBrush?

no, that's the point of wrap mode 2.

cryrid

You'll need all three axis if you want to drag an alpha on that is meant to affect more than one direction (as most are). That is where Orb's method will come in handy vs just wrapping standard brush strokes. Otherwise you'll have to draw down the alpah's you want first in the center of the mesh, offset the document to move them to the edges, and then project the result back onto a new plane (zproject or matchmaker or displacement, etc). It's still quick, but it means more tools to manage and keep track of.

Computron: true i drank a redbull and thought about it again and i understand now allmost 5am here, really need to finish this.

thanks for all the help people.

Jonas Ronnegard

btw really thanks for sharing orb, its great being able to watch the texture tile as you work on it, can see what sticks out the most right away.
