ZModeler and ripple

ZBrush Usage Questions
#1

Im sure this is an old problem…
I have here a small object which im trying to model with ZModeler.

Only way to avoid most of rippling is to scale size of the object. Is there any other way to do this?

ZBrush has an ideal scale it likes to work at. The oldest problem seems to be a lack of understanding or practice. Lose about 1/2 or more of those points and work deliberately when moving and scaling things with that new ZModeler brush. :wink:

Well less philosophy and more solutions, maybe next time. There is reason why i use lots of polygons and why some objects needs to be strictly at certain positions.

Some of this applies. http://www.zbrushcentral.com/showthread.php?192644-Applying-Dynamesh-at-full-resolution-is-very-blocky&p=1132132&viewfull=1#post1132132

Kake:
Which ZModeler stuff did you use when this happened?

#6

And is that possibly a ZRemeshed sphere, rather than a QSphere or QCube which both allow you great freedom in the Initialize pallette in several regards, letting you set enough divisions to block in a form quickly.

|It shouldn’t matter what sort of object hes editing, if ZModeler is causing ripples I want to know what he did to make it happen. That way I can try it my self to see what happens and why. This keeps me from sending him off on merry goose chases for no good reason.

I use DynaMesh all the time with ZModeler, and things that have been ZRemeshed and things made from ZSpheres. Theres NOTHING wrong with doing that.
I very rarely need the initialize thing. In fact I think I have used it maybe three times, its neat, but thats about it.

It happens at least with QMesh and Extrude functions. Objects varies from QSphere to PolyMesh3D Cylinder. I can repeat this all the time with projects no matter what is the workflow. The problem is that if object goes smaller and smaller, the ripple effect deepens. I thought this was some kind of setting problem in general.

AHHA!
I got it to happen too, you are using QMesh and Extrude to shrink your object right?
I think you need to use something else, that sort of not what they were intended to do.

Try using Scale in the Deformation Pallet, XYZ under Size in the Geometry Pallet or Scale with the Transpose tools.
All of those should work, differently from each other but they don’t wrinkle your object.

I actually LIKE what this does, I shrank a ZRemeshed sphere down ten or twenty times and then back up, its a neat effect!
It keeps all the wrinkles and stuff when you get it back to normal size so this is great for making semi-random lumps…

“Try using Scale in the Deformation Pallet, XYZ under Size in the Geometry Pallet or Scale with the Transpose tools.

This is exactly how i treat objects, but it still happens.

#11

this is odd…
I think I broke it.

Now Im having similar problems even after restarting ZBrush…

#12

Reboot the machine (I know you don’t want to turn it off) :wink:

#13

I had to reboot, that stupid tablet service dies all the dammed time…

So this is an odd problem and I don’t see why it happens but it might help explain Dougs deeply encrypted hintings.
Try the exact same process with a cube instead of a sphere and tell me if this happens still.
It looks like ZBrush isn’t coping with the smoothness of a sphere in the same way it copes with sculpted or angled objects.

Using QMesh with PolyLoop:


  • If you work on a Sphere3D that has been PM3D’d things work fine.
  • If you Dynamesh it It works fine, effecting only one “polyloop” or in this case strip.
  • If you ZRemesh it things change, you will get odd effects, like what you are seeing, and others, for me the ripple thing only happens when I shrink the object a lot.
  • If you work on a Cube3D (or anything other than a sphere as near as I can tell) everything should work as expected.

So to decrypt what Doug may or may not have said, a pure ZRemeshed Sphere3D screws with ZModeler. Or something.

#14

You broke the code :wink: Workflow ( or method of working), however you wish to term it can make or break you. Steps taken deliberately and in the proper sequence will help you get more done with less frustration.

#15

So after experimenting it looks like you can work with anything OTHER than a ZRemeshed Sphere3D and things work as expected.
Something odd about that…

If you sculpt it a little, and by little I mean a tiny amount, and THEN ZRemesh it it works fine.

This seems like a bug to me.

#16

I know of one thing for sure that would help me feel less frustrated.

@zber2 So nice of you to join us with your technological expertise (after 2 days), do you have something helpful to say here? :confused:

#18

do you have something helpful to say here?

Careful there Doug, ZBer has been teaching people on this site ZBrush for a very long time, and he is very very good at it.
