We introduce the creation of textures using Pencil+ 2 Material's [Advanced Settings] / [Gradation Offset Map].
We shall create a texture where the light curves like in hand drawn illustrations.

Create a sphere primitive so that it is easy to observe the curving light effect.
Go to the [Create] panel and press the [Geometry] button, then select [Standard Primitives]. Finally press the [Sphere] button in the [Object Type] rollout.
Create a Pencil+ 2 material and configure a simple texture using 2 gradations.
We now completed the basic preparation and can start working on the creation of the actual texture. *See the tutorial "Using Pencil+ 2 Materials" for an introduction to the creation of materials.
Go to [Pencil+ 2 Material] / [Gradations] rollout / [Advanced Settings] / [Gradation Offset Map] and check the [Enable] check box.
Press the [Map] button, select [Mask] in the [Material/Map Browser] and press [OK].
- Press the [Map] button in the [Mask Parameters] rollout, select [Falloff] in the [Material/Map Browser] and press [OK].
Adjust the [Falloff] parameters.
Choose [Fresnel] from the [Falloff Type] pull-down list and adjust the curve in the [Mix Curve] rollout so that it looks like the one shown here.- Our texture now makes the light curve around the sphere.
However, regardless of the light, our texture creates an edging effect. We shall therefore define the curvature area.
Press the [Mask] button in the [Mask Parameters] rollout of step 5, select [Gradation Ramp] in the [Material/Map Browser] and press [OK]. 
Set the [Gradient Type] in the [Gradient Ramp Parameters] rollout to [Lighting] and adjust the light curving using the [Gradient Bar].

Tips!
You can emphasize the hand drawn image appearance, as shown in this image, by similarly assigning a map in [Pencil+ 2 Material] / [Basic Parameters] rollout / [Glossiness Map].
