I will show you also how to auto screentone speech bubbles for that dark foreboding feeling.
Click on the text tool, it's the icon that looks like the letter A. Click on your art work in the panel area you wish to use text. The properties panel will appear as above. Where I have pointed out in red, tick for out line. Change the number up or down for the thickness of the white outline.
Tick and adjust the other options for other effects. Now for the speech bubble click where I marked in red the tab called Dialogue Balloon Settings.
Click generate Dialogue Balloon and a new window will appear. Hit ok when you are satisfied with the shape. Don't worry about size or colour yet. We do that elsewhere.
Where I marked in red this is your settings, from colour to size to using tones instead of standard white. You can simply adjust the size by clicking the blue corners and when you move it the text moves as well. Below the Generate button is select dialogue balloon from materials. This is where all the premade samples are and you can simply select and tinker with and change it. To your needs. Mostly these premades are perfect.
Now lets move on to wiggly text. This is easier than some think. Firstly use the text tool again and type out your sound effect. I am going good ol' Swish.
When you have your text, in the layers tab you will see your text and what it says. Right click and rasterize Keep original and hide it from view by clicking the eye icon. Now select with square selection tool around your text. Go to edit tab. Move and Transform and go to MESH EDIT! Not perspective or skew, mesh!! This is something a lot of people seem to miss.
You will see your selected area has red lines with a lot of points. As displayed below.
Now place them in odd places to fully distort and wave your text. See mine below for an example.
Hit ok when you're happy and you will have smooth and wiggly or weirdly distorted text.
You can 100% use the other transform tools but for wiggly and like we see in comics, use mesh. Perspective is best for that tiny to huge text and then mesh to make it wavy. Of course you can use this mesh feature on any raster image and to my knowledge tones. As long as it is selected and you have the layer you wish to distort selected, it should work. Hope this helps out a bit. Any questions, just ask.
Next tutorial is perspective ruler, other rulers and focus lines as well as other uses for the render tab.
