Mesh Form is a highly flexible tool that lets you apply various textures such as clothing.
Prepare an illustration, whose the skirt has no texture.
Open ①the Material tool, and select ②"Clothe Patterns (Color)".
Select ①"Tartan check 01(red)".
Once the texture is applied, open ①the Tool Selection window and select ②Transformation tool.
Select ①Mesh Form, to adjust the size of the material.
①Division Xlets you change the horizontal partition by dragging the slider left and right.
②Division Y lets you change the vertical partition by dragging the slider left and right.
By increasing the number of divisions, you can distort the image as precisely as you want.
Here is a comparison to show the difference in smoothness.
Dragging ①the Smoothness slider left and right will let you adjust the smoothness after transforming.
Turning ①Repeat on will let you use the repeat function.
②Repeat X lets you change the horizontal density of the shape by moving the slider left and right.
③Repeat Y lets you change the vertical density of the shape by moving the slider left and right. By using the repeat function, you can adjust the density of the shape to fit your illustration, for a more natural expression.
①Phase X lets you change the horizontal position of the pattern by dragging the slider left and right.
②Phase Y lets you change the vertical position of the pattern by dragging the slider left and right.
By turning ③Interpolationon, you can smoothen the pattern of the material.
Once you are finished fixing the settings, drag ④the handle to distort the material to fit the skirt.
Once you are done distorting the material, tap on ①✓ to finish.
Open ①the Layer window, and select ②the current layer and turn on ③Clipping, to prevent the material from sticking out of the drawing.
Apply the texture to the base in the same manner, and you are done.
