Can be accessed by clicking the icon next to the Condition Mask layer (and next to Degree); this gives even more access to various ways to apply your material layer.<\/p>\n\n\n Height\/Color Limiter Conditions<\/strong><\/a>: Select how the depth, color, and Gloss of your brush strokes are affected by colors, height, and other parameters.<\/p>\n\n\n\n A condition mask is used to apply effects or paint based on specific conditions of the model’s surface, such as curvature or ambient occlusion. This function allows you to, for example, paint more in a cavity, more on peaks, or more on a specific color or even a mask. <\/p>\n\n\n\n Conditions refer to paint masking options that allow you to restrict painting to specific areas of a model based on surface curvature, lighting, or other criteria.<\/p>\n<\/blockquote>\n\n\n\n This is often used in the Paint Room with Smart Materials to target specific areas like crevices or raised surfaces. It\u2019s a helpful way to paint in detail, such as grime around nuts or rusty colors in rust spots.<\/p>\n\n\n\n <\/p>\n\n\n\n Smart Material Method: <\/strong><\/p>\n\n\n\n Conditional Painting:<\/strong><\/p>\n\n\n\n Remember to set it to Always<\/em> when you finish using this option.<\/p>\n<\/blockquote>\n\n\n\n To use any condition remember first to Edit > Calculate curvature and AO maps.<\/p>\n\n\n . Using a Smart Material (recommended):<\/strong> This non-destructive method uses a procedural material layer that automatically masks itself based on the model’s geometry. Go to the Textures menu at the top of the interface, select Calculate Occlusion. . Create a new layer and attach a Smart Material:<\/strong> Next, apply a new Smart Material that uses the baked textures to create the mask.<\/p>\n\n\n\n In the Layers panel, create a new layer where you want to apply your paint or effect. . Adjust the Smart Material:<\/strong> To customize your mask, edit the attached Smart Material.<\/p>\n\n\n\n Right click the Smart Material attached to your layer to select “open the Smart Material Editor” detaching it first. . Conditional painting:<\/strong> For a more direct, manual approach, you can activate the Concavity masking mode on your brush.<\/p>\n\n\n\n Select a painting tool, like the Paint Brush, from the Tools panel.At the top of the interface, locate the “Conditions” dropdown menu with the different masking conditions. It is usually set to No Masking by default. <\/p>\n\n\n\n On the upper right side you can adjust degree & contrast<\/p>\n\n\n Remember that Conditions only work on freeze for sculpt surface mode or Surface Paint on vertex on Paint Room.<\/p>\n\n\n\n But the standard sculpting<\/em> brushes do not respect conditions, only work on Freeze mask to restrict where surface sculpting tools will be applied to the surface of the model.<\/p>\n<\/blockquote>\n\n\n\n Always:<\/strong>\u00a0Applies to every pixel of the layer. More on Bumped:<\/strong>\u00a0Acts stronger on pixels that extrude outward. Only displacement of the current layer is taken into account. These two condition options seem to only work on layers with displacement applied. 1.<\/strong> First, you need to add Conditions<\/strong><\/a> to Degree value (more on convex like example) to see \u201cvase\u201d options. – Overall Cavity Modulator![\"\"](\"https:\/\/3dcoat.com\/documentation\/wp-content\/uploads\/2022\/09\/heightcolorlimiter.jpeg\")

Step 1: Bake the texture maps. First, 3DCoat needs the model’s curvature and ambient occlusion data to understand its topology.<\/p>\n\n\n\n
In the dialog box, you can adjust settings like depth and contrast. Click Calculate.
Go to the Textures menu again and select Calculate Curvature. In the dialog that appears, you can adjust the “cavity” and “long-range” intensity to define the scale of the details you want to detect. Click Calculate. <\/p>\n\n\n\n
In the Smart Materials panel, find a material that works as a base. For a simple mask, a standard dirt or rust material is a good starting point.
Right-click the Smart Material and select Attach to current layer.
The Smart Material will apply itself to the selected layer using its built-in conditions, which often include curvature or AO. You can now paint on this layer and the effect will be confined to the crevices. <\/p>\n\n\n\n
In the editor, navigate to the layer that controls the crevice color (e.g., the “Dirt” or “Cavity” layer).
Click the condition icon to open the Condition settings. Here, you can adjust parameters like the Cavity Width, Cavity Degree, and Contrast to fine-tune exactly how the mask appears in the crevices.
Once you have your desired masking value, attach again and you can either paint on the layer, fill it with a new color, or continue modifying the smart material. <\/p>\n\n\n\n
Change the condition to Concavity. This will ensure that your brush strokes only apply to the concave (crevice) areas of your model.
Paint on your model. You may need to adjust the brush’s falloff to get a more precise effect.<\/p>\n\n\n\nThese conditions are<\/h3>\n\n\n\n

More on Concave:<\/strong>\u00a0This applies to areas that are more concave and lets you fill crevices. The condition allows acting stronger on concave areas. The cavity map will be generated as a separate layer automatically.
More on Convex:<\/strong>\u00a0Applies to more convex areas, applying the material to more rounded external surfaces. The condition allows acting stronger on convex areas. The cavity\/curvature map will be generated as a separate layer automatically.
Less on Concave:<\/strong>\u00a0Similar to More on Concave, but applies in the opposite form by allowing a little less in concave areas and a little more in convex.
Less on Convex:<\/strong>\u00a0Similar to More on Convex, but applies in the opposite form by allowing a little less on convex areas and a little more in concave.
More on Flat:<\/strong>\u00a0Applies only to flatter surfaces.
More on Curve:<\/strong>\u00a0This applies only to more curved surfaces.
More on Lit:<\/strong>\u00a0The condition allows you to act stronger in lit areas. Uses an Ambient Occlusion map to determine placement: you need to calculate the ambient occlusion map to use this condition. Use Edit\u2192Calculate Occlusion.
More on Shadow:<\/strong>\u00a0The condition allows you to act stronger, darker shaded areas. You need to calculate the ambient occlusion map to use this condition. Use Edit\u2192Calculate Occlusion.
More on Top:<\/strong>\u00a0Applies only to the upper areas of the surface.
More on Bottom:<\/strong>\u00a0Applies only to the bottom areas of the surface.
More on Sides:<\/strong>\u00a0Applies only on the sides of the surface. The condition acts stronger on the sides of the model.
More on Bright:<\/strong>\u00a0Acts stronger on bright pixels. The only color of the current layer is taken into account.
More on Midtone:<\/strong>\u00a0Acts stronger on pixels with medium brightness. The only color of the current layer is taken into account.
More on Dark:<\/strong>\u00a0Acts stronger on dark pixels. The only color of the current layer is taken into account.
More on Picked:<\/strong>\u00a0Acts stronger on pixels with a color close to the currently picked color. The only color of the current layer is taken into account.<\/p>\n\n\n\n
More on Dent:<\/strong>\u00a0Acts stronger on pixels that extrude inward. Only displacement of the current layer is taken into account.<\/p>\n\n\n\n

2.<\/strong> Focus on a new edit icon -it looks like a vase-, this was added and did not exist before, and it is with the spin edges that the update function is configured. It is the additional cavity width: The 0 value means that the cavity is taken from the materials settings as-is.
Values less mean sharper cavity, more than 0.5 – widening of the cavity. Or course, you need an RGB cavity layer in the scene to vary the cavity width.
It works only on such conditions<\/strong><\/a>: more on concave, more on convex, less on concave, less on convex, more on flat, and more on curved (you can use any of these modes).
