建筑定制

UNIGINE provides a set of built-in materials for generated buildings: they are inherited from mesh_base and named according to the rules. You can also create your custom textures and set up materials. However, your textures should meet a set of requirements described below.UNIGINE 为生成的建筑提供了一套内置材质：它们继承自 mesh_base 并根据规则.您还可以创建自定义纹理并设置材质。但是，您的纹理应该满足下面描述的一组要求。

Four types of textures should be prepared for a building: a texture for the basement, a texture for the wall with windows (and sometimes doors), a texture for the solid wall, and a texture for the roof. The UV map of each part of the building depends on the size of the wall segment that is shown on the texture.应该为建筑物准备四种类型的纹理：地下室的纹理、带有窗户（有时还有门）的墙壁的纹理、实心墙的纹理和屋顶的纹理。每个的 UV 映射建筑物的一部分取决于纹理上显示的墙段的大小。

注意

Textures for walls differ depending on the part of the building they are applied to: if a texture is applied to Basement, it should depict Basement and Underground Basement.墙壁的纹理根据它们应用于建筑物的部分而有所不同：如果纹理应用于 Basement，它应该描绘 Basement 和 Underground Basement。

• For Underground Basement and Basement, a single texture for a wall is applied. The texture height corresponds to the height of all these parts (in sum), and the texture is stretched vertically to fit this part of the building.对于 Underground Basement 和 Basement，应用单个墙壁纹理。纹理高度对应于所有这些部分的高度（总和），并且纹理被垂直拉伸以适应建筑物的这一部分。

• For the Ground Floor, an individual texture is applied. The texture height is applied to the building using the Row Size value as the floor height.对于 Ground Floor，应用单独的纹理。纹理高度使用行大小值作为楼层高度。

  For Upper Floors, a single texture for a wall with windows is applied.For Upper Floors, a single texture for a wall with windows is applied.

  There are two parameters — Rows per Texture and Columns per Texture — that form a grid for this texture.There are two parameters — Rows per Texture and Columns per Texture — that form a grid for this texture.

  

  The texture for the upper floors with windows is applied wherever possible along the wall from the first floor upward and from the center to the building corners horizontally and is cut according to these imaginary grid lines, creating one surface. Edges are tiled using the solid texture and form another surface.The texture for the upper floors with windows is applied wherever possible along the wall from the first floor upward and from the center to the building corners horizontally and is cut according to these imaginary grid lines, creating one surface.

  There are two parameters — Rows per Texture and Columns per Texture — that form a grid for this texture.有两个参数——每个纹理的行数和每个纹理的列- 为这个纹理形成一个网格。

Edges are tiled using the solid texture and form another surface.上层带窗户的纹理尽可能沿墙壁从一楼向上，从中心到建筑物的角落水平应用，并根据这些假想的网格线切割，形成一个表面。边缘使用实体纹理平铺并形成另一个表面。

• For Roof, two textures should be applied — for the roof and the ridges. Ridges are used to cover the connection of two roof planes.对于 Roof，应该应用两个纹理——屋顶和山脊。脊用于覆盖两个屋顶平面的连接。

  Roof texture屋顶纹理
  Ridges texture山脊纹理

  The roof material can be used as is or change the color based on the imagery data. Enabling the corresponding option allows multiplying the material albedo by the color taken from the imagery data.屋顶材料可以按原样使用，也可以根据图像数据更改颜色。启用对应选项允许将材质反照率乘以从图像数据中获取的颜色。

注意

Each material should be inherited from mesh_base.每个材质都应该从 mesh_base 继承。

For materials to be correctly applied by Sandworm to the generated buildings, follow these rules:要让 Sandworm 正确地将材料应用于生成的建筑物，请遵循以下规则：

• Define a prefix that a group of materials applied to walls (basement, ground floor, and upper floors) will use.定义一组应用于墙壁（地下室、底层和上层）的材料将使用的前缀。

  You can use the source data material value as the prefix of the material. In this case, the material will be applied automatically to all buildings that have this value assigned.您可以使用源数据材料值作为材料的前缀。在这种情况下，材料将自动应用于所有分配了该值的建筑物。

  Roof materials also can use a key value of source data as a prefix. In this case, the material will be applied automatically to all roofs that have this value assigned.屋顶材料也可以使用源数据的键值作为前缀。在这种情况下，材质将自动应用于所有指定了该值的屋顶。

  If your source data don't have material details, you can choose an arbitrary name.如果您的源数据没有材料详细信息，您可以选择任意名称。

• Materials should use the following name postfixes:材料应使用以下名称后缀：

  • *_basement_sw — material for Basement and Underground Basement, a mandatory material which is an anchor for other building materials, except roofs.*_basement_sw — 用于地下室和地下室的材料，这是一种强制性材料，是除屋顶以外的其他建筑材料的锚。
  • *_ground_sw — material for the Ground Floor wall without doors and windows*_ground_sw — Ground Floor 无门窗墙的材质
  • *_ground_windows_sw — material for the Ground Floor wall with doors and windows*_ground_windows_sw — 带门窗的 Ground Floor 墙的材质
  • *_upper_sw — materials for the Upper Floors wall with doors and windows*_upper_sw — 带门窗的 Upper Floors 墙的材质
  • *_upper_windows_sw — materials for the Upper Floors wall without doors and windows*_upper_windows_sw — Upper Floors 无门窗墙的材质
  • *_roof_sw — material for Roof*_roof_sw — Roof 的材料
  • *_ridge_face_sw — material for the Roof ridges connecting the roof sections*_ridge_face_sw — 连接屋顶部分的 Roof 脊的材料

The basic set of building materials is available in the /core/materials/buildings/ folder. /core/materials/buildings/ 文件夹中提供了基本的建筑材料集。

Naming Example命名示例#

Let's assume we have an area with buildings, which can be made of bricks or wood. If we use OSM data with their specific naming, we should use the following prefixes for building materials:假设我们有一个有建筑物的区域，它可以由砖块或木头制成。如果我们将 OSM 数据与他们的具体命名，我们应该使用以下前缀来进行建筑材料：

Building	OSM Value	Material Names
made of bricks用砖块做的	brick	brick_basement_sw.mat brick_ground_sw.mat brick_ground_windows_sw.mat brick_upper_sw.mat brick_upper_windows_sw.mat
made of wood木质的	wood	wood_basement_sw.mat wood_ground_sw.mat wood_ground_windows_sw.mat wood_upper_sw.mat wood_upper_windows_sw.mat

Then, the roofs of these buildings can be covered with tiles, metal, or concrete. According to the OSM roof material naming, we should name the roof materials as follows:然后，这些建筑物的屋顶可以用瓷砖、金属或混凝土覆盖。根据 OSM屋顶材料命名，我们应该将屋顶材料命名如下：

Roof	OSM Value	Material Name
covered with tiles用瓷砖覆盖	roof_tiles	roof_tiles_roof_sw.mat roof_tiles_ridge_face_sw.mat
covered with metal用金属覆盖	metal	metal_roof_sw.mat metal_ridge_face_sw.mat
covered with concrete用混凝土覆盖	concrete	concrete_roof_sw.mat concrete_ridge_face_sw.mat
