Easy Way to Create Bas Relief 3D sculpture Using Zbrush

Have you seen Bas relief sculpture on the walls of cave before? Do you want to draw your realistic face in the coin sculpture? 

Bas Relief is a kind of sculpture in which the figures are raised a few inches from a flat background to give a three-dimensional effect. However new possibilities open up that we never learn it before.

In this tutorial, we are going to show you how to create bas relief into the 3d model using Zbrush.  You might need to draw on a coin design or medallion design etc. Let’s come take a look at how it’s done. This tutorial is help you to new idea and a lot of tips and tricks. Let’s start your design journey.

 

Examples of Bas Relief Sculpture

For this project you’ll need the following:

Laptop & Computer
Zbrush Software
Pen Tablet – we are using Wacom for this tutorial


 

1. Create an alpha mapping images using Adobe Photoshop

We are using alpha to create bas relief sculpture.

What is Alpha?
An Alpha is a grayscale intensity map. It can be used to represent intensity, masking, and similar things. For example, bump maps and displacement maps (both in ZBrush and in other programs) are both alphas; the grey intensity represents the height or depth of the bump or displacement.

Often times image from Photoshop are used in Zbrush or other programs, such as After Effects, Maya, and Blender that support alpha channels. This grayscale channel has black areas to indicate transparency and white sections that are opaque.

The alpha channel can be found in Photoshop’s Channels palette and is labelled as channel #4.


2. Saving the image as a JEPG or PNG format files, the alpha channel is included with the image


3. Open Zbrush


4. Create a Cylinder model


5. Hit Edit Mode and Make polymesh 3D

Click the Edit button on the Top Menu Bar then Make polymesh 3D on the right Menu ToolBox.


6. Scale the coin model

We can adjust the scale – Thickness of the coin model.


7. Use DynaMesh

DynaMesh is newest base mesh generation tool. It has been designed to create low and middle resolution sculpting stages, making it a perfect way to create your base mesh before diving deeper into all the powerful traditional ZBrush sculpting and editing tools.

Go to right Menu ToolBox > Select Geometry > DynaMesh


8. Import Alpha Image

 


9. Select Mask Pen Tool

Masked areas are not simply on/off. Instead, they can be unmasked, partially masked to some degree, or fully masked. The effect that operations such as sculpting have on masked areas of a model depends on the intensity of the mask at each point.


10. Masking Intensity

Once painted mask by intensity. You can paint masks on your object directly by holding down the CTRL key while painting on the model.


11. Press Arix Z (Blue) + Drags your mouse


12. Clear a Mask

Hold down the CTRL key and drag on the canvas outside the model. Any visible amount of dragging will do.


13. That’s it. We just completed base 3D Coin Sculpting
