How to Create a Pearl Brush from Gradient Meshes in Adobe Illustrator

preview

In today’s tutorial we will learn how to control transparency of gradient meshes with the help of blending modes, and by adjusting color transition between mesh points and changing its opacity. Moreover after reading this tutorial, you’ll be able to create Illustrator brushes from gradient meshes of any difficulty with the help of free Mesh Tormentor plug-in. Let’s get started!

Tutorial Details

Final Image

As always, this is the final image that we’ll be creating:

Step 1

Open Adobe Illustrator and create a new document (File > New). In the dialog box, set the RGB color mode and the size of the artboard, which depend only on your personal preferences.

Step 2

Take the Rectangle Tool (M) and create a rectangle with linear gradient fill. I used two colors for this gradient: R= 233; G = 230; B =228 and R= 158; G = 143; B =138.
pearl02
This created rectangle will be used as our background, so you can use completely different fill. But the background should exist as an object.

Step 3

Let’s begin creating our pearl. Take the Ellipse Tool (L) and draw a circle with light-brown fill R= 235; G = 230; B =227.
pearl03
And now transform our circle into a gradient mesh. To do so, go to the Object > Create Gradient Mesh… and in the dialog box set a number of rows and columns which is two.
pearl04

Step 4

Take the Mesh Tool (U) and create a new mesh point by clicking on the point A.
pearl05
Now we need to recolor a couple of mesh points. Use the Direct Selection Tool (A) to select them. The points’ location and their new colors are indicated on the figure below.
pearl06

Step 5

Create an ellipse with the color of fill R= 247; G = 239; B =235 with the help of the Ellipse Tool (L) and rotate it to some angle with the Selection Tool (V), as it is indicated on the figure below.
pearl07
Transform the ellipse into a gradient mesh (Object > Create Gradient Mesh).
pearl08

Step 6

Select and color the center point of the gradient mesh into brown R= 189; G = 166; B =154.
pearl09
Now select the entire gradient mesh and set the Multiply blending mode in the Transparency panel.
pearl10
This action allowed us to make the light edges of the gradient mesh semi-transparent. I want to remind you that white became transparent after the Multiply blending mode application.

Step 7

Let’s create some highlights on the surface of our pearl. Create one more gradient mesh in black (R= 0; G = 0; B =0) as an ellipse as we did in our previous steps. Color the center point of the gradient mesh white.
pearl11
Select the entire gradient mesh, then in the Transparency panel, set the blending mode to Screen.
pearl12
As you can see, the edges of the object became transparent, since black becomes transparent after application of the Screen blending mode.

Step 8

I don’t like the way transparency is spread from edges to the center of the object. So let’s see how we can control the transparency in gradient meshes. The distribution of color between adjacent mesh points depends on the length ratio of handles on their connecting mesh line, i.e. if I want to distribute some transparency to the center I need to reduce the handles of white point and increase the handles of black points on the outer edges of the object.
pearl13
Undoubtedly, these actions changed the picture, but this is still not quite the effect I’m trying to reach.
pearl14

Step 9

Select all the points which are located on the edges of the gradient mesh (the central point should remain unselected) and set 30% Opacity in the Transparency panel. Starting with Adobe Illustrator CS5, we can control the mesh point opacity.
pearl15
Now, I finally have the desired result.
pearl16

Step 10

Using the described technique, let’s work on creation of some more highlights on the pearl. Its location is indicated on the figures below.
pearl17
pearl18
pearl19

Step 11

Now, let’s use the principles described above to create a drop shadow. The points that are located on the borders of gradient mesh are white and have 0% opacity. The central point is colored in grey R= 140; G = 140; B =140. The Multiply blending mode is applied to entire gradient mesh.

Step 12

The pearl is ready, let’s group all its objects for our convenience (Cmd / Ctrl + G). Now we can create brushes from this group despite the fact that Illustrator’s brushes cannot contain gradient meshes.
pearl21
The opportunity became available only due to free Mesh Tormentor plug-in, which you can download here. After installation of the plug-in, open its panel (Window > Mesh Tormentor)
pearl22

Step 13

Select a group with a pearl, then click on the Make BMG button in the Mesh Tormentor panel.
pearl23
Drag the received objects into the Brushes panel, then choose Scatter brush in the opened dialog box.
pearl24

Step 14

Leave the brush’s parameters unchanged in the opened dialog box of Scatter Brush Options. We’ll work with parameters after our brush is created and applied.
pearl25
Take the Paint Brush Tool (B) or any other drawing tool and create an arbitrary path.
pearl26

Step 15

And now let’s specify the brush settings. To do so, click twice on the icon for this brush in the Brushes panel, which opens the dialog box with parameters. Check the Preview option to observe the current changes.
pearl27
Everything is ready to transform the brush stroke back into gradient meshes. Keep the path selected, go to the Object > Expand Appearance.
pearl28

Step 16

Click on the Convert BMG into mesh in the plug-in’s panel.
pearl29
As you can see, we received a string of pearls, which are gradient meshes.
pearl30

Step 17

If in your work you use Graphic Tablet, then you can set the brush size to be determined by pressure. You also need to set a range for the size of your brush.
pearl31
The brush with such parameters allows to create an illusion of perspective, where objects that are closer to the viewer look bigger than the ones further away.
pearl32

Step 18

After transformation of the brush stroke into a group of gradient meshes (Object> Expand Appearance, then click on Convert BMG button), we need to change the sequence of the pearls on the left part of the necklace so they’re perspective appears from front to back.
pearl33
The sequence of the pearls can be altered with the help of the Send Backward command (Cmd/Ctrl + [ ) and Send to Back command (Shift + Cmd/Ctrl + [ ).
pearl34

Step 19

In additional to the drop shadow we added previously, we also need to add a shadow from the neighboring pearls to enhance the realism of the perspective. Create a circle with gradient mesh fill from brown to white. Apply the Multiply blending mode to it and place it on one of the pearls.
pearl35

Step 20

Now we need to hide parts of shadow which extends beyond the neighboring pearl. Select the gradient mesh which forms the shape of the neighboring pearl, then go to the Object > Path > Offset Path and set the offset value to 0 px.
pearl36

Step 21

Move this path up from its current group to above the form of a shadow in the Layers panel.
pearl37
pearl38

Step 22

Select this path and a form of the shade and go to the Object > Clipping Mask > Make or use Cmd/Ctrl +7 shortcuts.
pearl39
Using this technique create shadows on other pearls.

  1. I loved the Pearls tutorial. However I found the steps from 22 onwards a little confusing. I did manage to create a “shadow” and placed this around the pearls but moving the layers around was confusing. I was happy with my finished project though. I will definitely be attempting more of them. Thnaks.
