Strange behavior of Curves

ZBrush Usage Questions
#1

Hello everybody!
Recently i’ve been watching ‘Mastering Zbrush with Paul Gaboury’ at Visualarium where he, besides other things, explains how curves work. I tried to replicate some of the tricks but found that some of the curve’s options simply do not work! I must note that Paul used 4R3 version of Zbrush and i tried to do the same things in 4R4 Patch 2 and 4R5. I know, many things changed in newer versions, but options like Max Points and Curve Falloff should function the same way as in 4R3, shouldn’t they??

Well, here are the main issues:

  1. Max Points simply do not work! [time on video 45:10]

  2. Curve Falloff strange behavior with Curve Editable brush (and with others) [time on video 43:18]

  3. Curve TriFill and QuadFill brushes do not snap to surface when Snap button is on. Only the first dot snaps, but the rest of the curve is parallel to canvas (regardless of the brush size). In Paul’s example it did snap [time on the video 39:20]

I’m not a newbie to zbrush, but i just can’t get those to work! I’ve checked all brush and curve related settings but with no luck. Maybe i’m missing something? Not that i can’t live without this functionality, but this is weird…
Please, somebody help me out with this! Thank you!

Has anyone encountered a similar problem? Nobody uses curves this way?? :slight_smile:

You posted no images, we don’t know what you’re trying to do either. It would help to help you.

Thank you for giving your attention! I’ve reuploaded images. It’s strange because they were there just yesterday :confused:

Try the CurveSnapSurface brush instead of CurveTriFill. Maybe masking the cheek area and using extract would accomplish what you need. And, I read somewhere that painting with any brush other than the Standard brush may lead to unexpected results.

I do use CurveSnapSurface instead of TriFill. Yes, there are workarounds, but why functions do not work as advertized?? In my examples I used the same brushes as in aforementioned video and nothing works. I tried with Standard brush - the same story - Curve Falloff is not working and Max Points is totally ignored… :frowning:

If your curves are not snapping to the surface and you have ‘Snap’ enabled then go to the ‘Picker’ palette and use ‘Cont Z’ instead of 'Once Z".

Thank you, zber2! My bad, I completely forgot about that option. One problem solved! :slight_smile:

I found this question through a search on the forum for a similar question I have. It seems that drawing the initial curve on the surface is not a problem, but when you start dragging the curve around to reposition it, it starts to come off the underlying surface and no longer seems to track (or stick to) the parent subtool. Is there a function somewhere to make the curve continue to stick to the background subtool while you drag it? Or can you reproject it back onto the background surface once you’ve dragged it about?

thank you,

Hello there ! I , too was struggling with the same problem with curve tri fill brush. And I was nearly frustrated. In the ZBrush classroom videos, they haven't shown the necessary settings. But, THANKS-BE-TO-GOD ! I found it. Under the stroke palette, click " CURVES". Then turn on " SNAP", " BEND", " LOCK START", " LOCK END ".

And now, the curves won’t pull off from the target surface.

P.S. After drawing the curves, don’t forget to click on the model. I was doing the same mistake. And I was not getting the subsequent forms. The shapes would diappear ,if I drew the new one.

Have a Blessed day !!!
