Pixel Layer

A Pixel Layer is the main object type used in a Heightmap.

It consists of a 2D pixel grid that can store color, material, and height information.

Pixel Data

Each pixel can store:

• a color index,
• a material index,
• and a height value.

This data is used to generate voxel-based heightmap content.

Pixel Layers and Pixel Objects

A pixel object is any object that contains or displays pixel data.

This includes Pixel Layers and Pixel References. Use Pixel Layer when referring to this specific editable object type, and use pixel object only when a concept applies to both.

For more information, see References.

Pixel Layer Properties

Size	Defines the size of the pixel grid.
Overlay	When enabled, a pixel is visible only if the pixel directly below it is also visible.
Height Mode	Defines how the height values of this layer interact with the layers below.

Height Mode Options

• Set: Uses the height value of the current layer and ignores the height below.
• Keep: Ignores the height value of the current layer and keeps the height below.
• Add: Adds the height value of the current layer to the height below.
• Subtract: Subtracts the height value of the current layer from the height below.
