ZBrush How to make 3D hollowing effect chart

The standard geometry in 1.ZBrush is a parameterized object, and parametric objects cannot be subtool under the extract command, so the parametric objects must be converted first.

Select Tool>sphere3d and create a sphere in the ZBrush. Click Tool>make polymesh3d to convert the parameterized sphere into a polymesh sphere for extract command. As shown in the figure.

To make more detail, enlarge the segment of the sphere, click Tool>geometry>divide to add the sphere to the fourth level subdivision (this step depends on the reader's computer configuration, the higher the better). As shown in the figure.

2. If the mask shape is determined, the mask can be created by holding down the CTRL key, and the mask on the sphere cannot meet our needs because the mask cannot be positioned precisely. As shown in the figure.

and the map because of the relationship between the UV distribution can be accurately distributed on the model, we can use the precise mapping of the ability to determine the mask distribution, the answer is yes. The Mask by intensity command under tool>masking controls the mask distribution according to the intensity of the texture grayscale.

Click Texture>import or click the picture position to asilefx_alpha_0329 the footage. As shown in the figure.

The rotation view found that the distribution of the map does not want our ideal, the two sides more poles, as shown in the picture, this is the distribution of UV, as long as the distribution of UV adjustment.

Click tool> geometry>lower res to reduce the sphere subdivision to the first stage, select TOOL>TEXTURE>UVP the UV distribution of the sphere to regulate Cheng distribution, so that the distribution of the map to achieve a more satisfactory effect. As shown in the figure.

Note: 1. Only in the lowest subdivision can adjust the distribution of UV, otherwise there will be the following prompts.

Under 3.tool>texture, there are several kinds of UV distribution, the calculation model has advantages and disadvantages, the choice depends on the situation. Returns the fourth level subdivision of the sphere, tool>masking>mask by the intensity option, so that the mask is distributed according to the grayscale of the map.

Select texture off under the texture menu, or select it as shown in the figure, remove the map, and find that the mask hides the black part of the map in the opposite direction we need, holding down the CTRL key and clicking the view so that the mask is reversed to reach our desired mask. As shown in the figure.

4. The next step is to use the extract command to produce a new hollow object.

Click Tool>subtool>extract to produce a new object with a certain thickness according to the mask of the sphere, and create a new layer in the Subtool, as shown in the figure.

Turn off the display of the sphere, you can see the hollow effect of the ball.

5. The edge of the hollow sphere is not very smooth, this is because the quality of the texture and the breakdown of the sphere, as long as a smooth, you can achieve the effect we want, as shown in the picture.

Select Tool>deformation>smooth, and select XYZ to tune its value to 100, as shown in figure.

Note: The smooth number of hollow spheres can be determined by the degree of smoothness, the resulting edge smoothness is also related to the subdivision, the higher the initial edge is more smooth.

6. Use the same method using figure asilefx_alpha_0347 to build another hollow sphere with different patterns. As shown in the figure.

Only to turn off the ball display after the discovery of two hollow spheres, as shown in the following figure, does not meet our requirements. We can use deformation to adjust the spatial relationship of two hollow spheres to achieve the desired effect.

Select the second set of hollow sphere layer (choose that floor empty sphere operation can according to personal preference), select Tool>deformation>size, select XYZ to adjust its value to-20. The two-storey empty sphere became a small one.

Observation found that because the map in the middle of the sphere is bound to have stretching, resulting in the hollow effect in the middle is relatively simple, in order to ensure its artistic effect, can be hollow ball slightly recommended rotation to rotate, so that the overall complexity of the enhanced.

Select the second set of hollow sphere layer (choose that floor empty sphere operation can according to personal preference), select Tool>deformation>rotate, select XY to adjust its value to 90.

Note: The XYZ under deformation is the axis that the selected command can affect, when adjusting smoothness and size, open three axes because the effect is to be done on the whole, and when rotating, as long as in a plane, so just select XY. This model is finished. As shown in the figure.
