Procedural Layers are non-destructive, algorithmically generated textures and patterns that offer infinite variation. These layer types can help you create materials like wood grain, speckled metal, and patterned stone. They can be more powerful when used as mask layers, but also as regular layers, and they have additional settings in Material Properties.

Scatter #

Introduced in Toolbag 5.03, Scatter Layers make it easy to distribute randomized elements across your mesh’s surface. For example, rocks, fragments of moss, bits of trash, and other detritus can easily add variation and believability to your textures. Scattered elements rely on the brush system, so you can load brush presets from the Library or create your own.

Unlike manual painting, the scatter remains non-destructive, so you can change its placement, density, brush shape, projection, and material properties at any time.

Scatter Layers have a new Visibility mask stack, too, which acts as a binary mask, so each scatter point will either draw at full opacity or not, depending on the mask’s contents. If you want the scattered points to fade out, a traditional soft-blended mask stack can also be added.

Setting	Description
Scatter Space	Determines the coordinate space used to generate and position the scatter points. 3D – Generates the pattern in 3D space. The result does not depend on the UV layout and can continue across UV seams. This mode is useful for consistently sized details distributed across complex geometry.  UV – Generates the pattern in UV space, allowing its scale, direction, and placement to be controlled through the model’s UV layout. This mode is useful when the pattern needs to follow a specific surface orientation. UV seams may interrupt the pattern, while overlapping UVs may produce repeated details. Decal – Generates the pattern inside a decal projection area. Move, rotate, or scale the decal to control where the scatter appears. This mode is useful for localized effects that should not cover the entire model.
Scatter Style	Determines which type of scatter pattern is used and what form its elements take. Point – Places one brush shape at each generated point. Its appearance is controlled by the Brush Tip and Material Properties settings.
Placement	Controls the distribution pattern for positioning the points. Grid – Arranges the points in a regular, evenly distributed pattern. Use Grid placement for ordered surface details or as a starting point for controlled procedural patterns. Random – Places points in a random pattern. The resulting arrangement is controlled by Count and Random Seed. Use Random placement for natural and irregular surface details.
Count	Sets the number of generated scatter points. When Placement is set to Grid, the number of points can be set separately for the X and Y axes.
Position X	Sets the horizontal position of the scatter pattern.
Position Y	Sets the vertical position of the scatter pattern.
Offset X	Offsets the scatter points along the X axis from their regular grid positions.
Offset Y	Offsets the scatter points along the Y axis from their regular grid positions.
Offset Random	Adds random variation to the point offsets, making the grid less uniform.
Offset Random Seed	Generates a different random offset pattern without changing the offset amount.
Random Seed	Generates a different variation of the current random distribution without changing its other settings.

Grout Scale Y	Sets a secondary, relative height value for the space between tiles.
