# Hull These settings control the main body of the spaceship, such as the number of hull sections, number of subdivisions, transformations and other shape altering properties like extrusion bumps.

These are the **Hull** properties and what they do: ### Hull Sections These determines how many numbers of hull sections the ship has by extrusion.

### Tolerance Normal threshold which determines if the faces needed to extrude the hull can include faces in the x and z axis.

Generally left to default values but exposed if you want some weird shapes. ### Auto Smooth Auto smooth angle for the mesh if using **Limit Smooth: None** and **Shading: Angle** in the **Plating** section.

### Triangulation Angle threshold by which to triangulate faces. This is used to make certain faces look angular or alter its shading.

### Quadify Angle threshold by which to quadify faces. This activates after triangulation. Triangulation is used in the mesh to basically to make most of its structure look angular then quadification is used to quadify the mostly flat faces that does not need the triangulation effect.

{% hint style="info" %} *The Auto Smooth, Triangulate and Quadify properties can affect the ships topology as well as its shading.* {% endhint %} ### Origin Mode This comes with two options: **Dynamic** and **Static** and determines the way the hull is extruded to form its sections. When using **Dynamic**, the hull sections will be extruded randomly in the front or back of the ship.

When using **Static**, the hull sections will be extruded only towards the front or the -y axis direction unless inverted.

### Hull Length The total length of the hull section. The resulting hull length will be randomized between the values of the mix and max properties.

### Edge Cuts This involves two properties which are the **Count** and **Seed**. This generates lateral edgecuts in random hull sections with the amount controlled by the **Count** property. The **Seed** property is used to randomize which of the hull sections these edge cuts are generated.

{% hint style="info" %} *Generating more faces this way creates more shape variety when using plating details or wing extrusions.* {% endhint %} ### Base Move Moves the mesh in the local x, y and z axis.

### Base Scale Scales the mesh in the local x, y and z axis.

### Base Rotation Rotates the mesh in the global x, y and z axis.

{% hint style="info" %} *The Base Rotation property rotates the mesh in global space meaning all proceeding detail will also rotate with it which is useful for aligning the ship to other objects in the scene.* {% endhint %} ### Bevel Offset The bevel properties are the primary control for the overall shape of the hull sections where all the other shape affecting properties follow.

They ensure that shapes generated from other settings create more variety compared to just being extruded from a simple cylinder. ### Bevel Segment The number of segments when beveling the hull sections.

### Bevel Profile This is made to generate the star shape profile when facing the front of the ship which of course you can modify like a normal bevel profile resulting to other shapes.

The bevel properties are key to generating the shape of the ship and when viewed from the front will give you an idea on how some details can be accidentally generated and made to look convincing.

### Section Scale The scale of the extruded hull section face. This is randomized between the values of the min and max properties.

### Section Interval The number of hull section count before the **Section Scale** property can take effect. For example, if you have 3 section intervals, this means scaling will only occur in every third hull section.

In Figure 18, you can see the ship has a total hull section of 8 so when the scale interval reached this number all of them have the same scale because the scaling only started at the 8th hull section. ### Uniform Scale Percentage for which uniform scaling can happen on a hull section. By default, the section scaling creates a random value for the x and z axis.

This property ensures that a particular hull section will have a single value used for scaling in the x and z axis making it look more cylindrical. ### Bump Mode This determines which elements are used for the bump effect. This bump is another shape altering property like the bevel properties.

There three options which decides what element you want to bump or offset: **Edge**, **Face** or **Both**. ### Bump Limit This controls what part of the mesh will be bumped or offset. **None** means all edges or faces can be used for bumping. **Adjacent** means an edge or a face can only be bumbed if it is one edge or one face away from a bumbed edge or face.

{% hint style="info" %} *Figure 21 is an extreme example but clearly demonstrates the difference between the two limits.* {% endhint %} ### Bump This contains the properties: **Count** and **Seed**. **Count** determines the number of edges or faces to be bumped and **Seed** randomizes which of them in the mesh will get offsetted.

### Bump Offset This determines the strength of the bump or offset. This is randomized between the values of the min and max properties.

### Offset Seed Random seed control for the bump offset property.

### Subdivision This contains two properties: Level and Smooth. Level is the amount of subdivision for the mesh and Smooth is the amount of subdivision smoothing.

The smoothing here is different from the Hull Smooth property as this is connected to the subdivision operation and smooths its result. This is exposed only for more shape variation possibility. ### Hull Smooth This represents the true smoothing property for the mesh and smooths all the vertices subdivided or not.

### Post Subd The level of subdivision for the subdivision modifier added to the mesh. This modifier will be intact in the modifier stack of the resulting starship mesh.

### Triangulate The percentage of faces to be triangulated. This is generated after the **Auto Smooth**, **Triangulation** and **Quadify** properties above to influence the pattern created by the plating details.

### Hull Seed This is the random seed control for all the hull properties above and randomizes their result if possible.

You can consider the hull seed property as the master control for the rest of the section seeds as changes in the hull will greatly affect the rest of the sections below it.
