How do you simply add clay to the crease and grooves?

Hi guys - I’m having trouble actually “building up” clay on my tool.

So, what I want to do is, in essence, “add clay” like you would in real life sculpturing. Add mass? might be it.

Now, I don’t know all the brushes so I might be using the wrong one - I tried this using “Clay Build up” (BCB) but that doesn’t really do what I want to (See diagram attached - i want to achieve the right side of it. A natural build up, as if I just added more clay to it)

It works on smooth surfaces of the tool - literally, builds up clay. But when it comes to grooves or creases, it doesn’t build up on the groove itself, but somehow only on the sides of it. It just builds up around it and messes up the tool.

Any way to get around this? Is it the brush? Any geometry subtool mode to solve it?Or is this impossible? (The tool is created in Rhino 3D, I hope that’s not an issue)

I’m sure there are many options but simplest would be to reduce your brush side and smooth along the crease. That will surely raise the deepest pasrt of the valley ahead of the valley walls. Then use clay build up or other brush as required.

For more local control consider using Masking: Mask by Cavity or Peaks & Valleys to mask the deepest recesses or mask by hand. Then invert the mask, blur a little and smooth locally with a brush or globally with functions in the Deformation menu (polish, smooth and so on).

Hi there and thanks for the reply - So I reduce my brush size, and when I do this, is there a particular brush I should use? Or may I use clay buildup brush and make it small 8or perhaps enlarge the tool/object too…)

Sorry if I wasn’t clear., What I said was Smooth which is a brush function. Hold the Shift key down on any brush and stroke over the area of interest. Focal Shift, Intensity, Size can be adjusted for smoothing alone while holding down Shift.

If you’re new to Zbrush then check out Michael Pavlovich’s Intro to Zbrush. An easy to search playlist covering all the basics.

Hi Tobor8man

Ah that helped, I really zoomed in and very carefully smoothed and built and smooth and…that worked. A bit painstaking though but I will make do with it - thanks!

Sorry I’m late to the discussion, but the regular “Clay” brush does this. However, it is one of the brushes that changes its behavior somewhat depending on whether Sculptris Pro is enabled.

  1. Use Dam Standard with Sculptris mode active to sculpt a deep furrow in the mesh.

  2. Select the regular “Clay” brush (not Clay Build Up, not Clay Tubes), disable Sculptris, and run it down the length of the furrow. You should see it “spackle” in the cavity.
