| • | To apply a lighting effect |
You can add light sources to an RGB or grayscale image to create the illusion of spotlights, floodlights, or sunlight. You can specify the type and number of light sources, the intensity of the light, and the color of the light. You can also create embossed reliefs by applying a preset or modifying color channel information. You can use a preset light and texture style, or you can customize a preset style and save it in the preset list.
