Even tough each LiveClay tool is different, the all share the essential action that is dynamic subdivision.
The 2 fundamental settings controlling this in 3DCoat are: Detail and Smoothing.

The detail slider control the degree of subdivision the brush perform along the stroke. It goes from 0 to 3.
High values will produce sharp strokes or very clear stamps (if stamp mode is used).
The triggering of subdivision is highly related to brush radius, smallest brush radius will automatically trigger subdivision.

The smoothing slider control the amount of smoothing tat is performed along the stroke. It goes from 0 to 1.
High values will give a very smudgy claylike feel that will even smooth surrounding areas, while lower values are very useful to produce nicer strokes, especially when spacing is activated in pen options.

A lot of Liveclay tools are empowered with 2 different set of controls:
- Procedural noise.
- Tool blend factor.

Procedural Noise let user add different types of noise effects to thei brsuh strokes. When mixed with the normal behavior of the tools some very interesting results can be achieved, ranging from distressed paper to granite or bumpy skin.

The Settings

Noise Amplitude: This settings control the overall scale of the applied noise. Smaller values will produce more grainy textures while larges values can generate more rocky effects for example.
Hard checkbox: checking this will provide sharper noise.
Type of noise: Various types of noise can be selected there. Basic, Perlin and six different Voronoi noise.
Level of details: This settings control the level of local subdivision performed by 3DCoat when applying the noise effect. It is entirely independent from the chosen LiveClay tool own lever of detail.
Slider range from 0 to 8 but higher values can be entered. Sometimes to achieve desired effect much higher values are needed.
Note that since 3DCoat is performing local subdivision for both the chosen tool and the procedural noise at the same time, so high values will impact performance.

Tool Blend Factor is a very important addition that is present in many LiveClay tools.
Those controls are there to let user decide what is going to happen when strokes intersect with geometry.

Using those controls 2 effect can be achieved:

3DCoat can either trigger a near voxel-like behavior, meaning the stroke will organically merge with the geometry it collides with
alternatively 3DCoat can automatically repel the colliding geometry.

Merge action: there you can either select NONE or REALTIME DETECTION.

To activate either repel\merge Realtime Detection MUST be selected.

Selecting NONE is equivalent to turning tool blend factor off.

Note that realtime detection is an heavy process and it can impact performances significantly depending on the other settings values like Level of Detail.

Collision actions: There you can choose either MERGE or REPEL.
