Processor Layers reference Input Maps from the texture project, such as Curvature or Ambient Occlusion, to help you easily create complex and convincing weathering. These are of great use as mask layers and when building Smart Masks, but they can also be used as regular layers and have additional settings in Material Properties.

Color Selection #

The Color Selection layer allows you to create a mask based on Material ID, Group ID, Object ID, or UV Island input maps. This is primarily used to mask separate mesh parts containing different material definitions.

Setting	Description
Source	Select the input map to generate the selection. An appropriate input map must be loaded in the texture project for this to function.
Color	Edit the color for this entry.
Color Dropper	Choose the color to sample from.
Threshold	Sets the color-matching sensitivity.
Delete	Remove this color selection entry.
Add New	Add a color selection entry.

Curvature #

The Curvature processor references the Curvature input map and helps to define the convexities and concavities of the mesh, making it useful when needing to mask or define borders and cavities.

Setting	Description
Intensity	Sets the strength of the curvature processor.
Invert Icon	Inverts the curvature processor.
Contrast	Sets the contrast of the curvature processor.
Contrast Center	Sets the middle point of the contrast effect.
Sharpen	Sets the sharpness or softness of the details.
Edge Intensity	Sets the strength of the edges or convex regions.
Edge Thickness	Sets the width of the convex regions.
Cavity Intensity	Sets the strength of the cavities or concave regions.
Cavity Thickness	Sets the width of the concave regions.

Direction #

The Direction processor layer references the normal input map and is useful for adding direction-based details such as snow, ice, dust, leaks, and more.

Setting	Description
Direction Axis	Sets which direction axis to use.
Intensity	Sets the strength of the direction processor.
Invert Icon	Inverts the direction processor.
Contrast	Sets the contrast of the direction processor.
Contrast Center	Sets the middle point of the contrast effect.
Sharpen	Sets how sharp or blurry the details are.

Dirt #

The Dirt processor references the Normal, Curvature, and Ambient Occlusion input maps. You can add a custom texture or a grunge map from the Library to create dust or dirt in the mesh cavities.

Setting	Description
Intensity	Sets the strength of the dirt processor.
Invert Icon	Inverts the dirt processor.
Contrast	Sets the global contrast of the dirt processor.
Sharpness	Sets how sharp or blurry the details are.
Grunge Map	Click to load or replace a texture map for the grunge effect.
Tri-Planar	Enable tri-planar mode for seamless texture projection.
Grunge Blend Mode	Sets how the grunge map is blended in relation to the other components of the dirt processor.
Grunge Intensity	Sets the strength for the grunge texture.
Grunge Invert	Inverts the grunge texture.
Grunge Contrast	Sets the contrast of the grunge texture.
Grunge Scale	Sets the tiling for the grunge texture.
Direction Intensity	Sets the strength of the direction effect, which isolates regions facing up and down.
Direction Invert	Inverts the direction effect.
Direction Contrast	Sets the contrast of the direction effect.
Crevice Intensity	Sets the strength of the crevices or concave areas, which is useful for defining where dirt or grime should appear on the micro-scale.
Crevice Contrast	Adjusts the contrast of the crevice effect.
Occlusion Intensity	Sets the strength of the occluded areas, which is useful for defining where dirt or grime should appear on the macro scale.
Occlusion Contrast	Sets the contrast of the occluded areas.
Reset Defaults	Resets to the original settings for this layer.

Height #

The Height processor layer references the Height input map and helps to define the displacement of the mesh, making it useful when needing to mask or define height detail.

Setting	Description
Intensity	Sets the strength of the height processor.
Invert Icon	Inverts the height processor.
Contrast	Sets the contrast of the height processor.
Contrast Center	Sets the contrast for the height processor.
Sharpen	Sets the sharpness or softness of the details.

Occlusion #

The Occlusion processor references the Ambient Occlusion input map and helps define the lighted and shaded areas of the mesh, making it useful when masking or defining cavities.

Setting	Description
Intensity	Sets the strength of the occlusion processor.
Invert Icon	Inverts the occlusion processor.
Contrast	Sets the contrast of the occlusion processor.
Contrast Center	Sets the contrast for the occlusion processor.
Sharpen	Sets the softness or sharpness of the occlusion details.

Scratch #

The Scratch processor references both Curvature and Ambient Occlusion input maps. It includes a Grunge Map slot to break the edges and a Scratch Map slot to add extra details.

Setting	Description
Intensity	Sets the strength of the scratch processor.
Invert Icon	Inverts scratch dirt processor.
Contrast	Sets the global contrast of the scratch processor.
Sharpness	Sets the softness or sharpness of the grunge details.
Occlusion Intensity	Sets the strength of the occluded areas, which is useful for defining where dirt or grime should appear on the macro scale.
Occlusion Contrast	Sets the contrast of the occluded areas.
Grunge Map	Click to load or replace a texture map for the grunge effect.
Grunge Tri-Planar	Enable tri-planar mode for seamless texture projection.
Grunge Blend Mode	Sets how the grunge map is blended in relation to the other components of the scratch processor.
Grunge Intensity	Sets the strength for the grunge texture.
Grunge Invert	Inverts the grunge texture.
Grunge Contrast	Sets the contrast of the grunge texture.
Grunge Scale	Sets the tiling for the grunge texture.
Scratch Map	Click to load or replace a texture map for the scratch effect.
Scratch Tri-Planar	Enable tri-planar mode for seamless texture projection.
Scratch Blend Mode	Sets how the scratch map is blended in relation to the other components of the scratch processor.
Scratch Intensity	Adjusts the intensity of the scratch texture.
Scratch Invert	Inverts the scratch texture.
Scratch Contrast	Sets the contrast of the scratch texture.
Scratch Scale	Sets the tiling for the scratch texture.

Reset Defaults	Resets the original settings for this layer.

Thickness #

The Thickness processor references the Thickness input map and helps define the thickness of mesh parts, making it useful when defining areas that include subsurface scattering.

Setting	Description
Intensity	Sets the strength of the thickness processor.
Invert Icon	Inverts the thickness processor.
Contrast	Sets the contrast of the thickness processor.
