Static models

A static model is any geometrical model imported "as is", without modification by CGA rules, textures, or individual vertices within CityEngine. They can be moved, scaled, and rotated but the geometry and the textures cannot be edited. This makes static models a good choice for landmark or hero buildings in your scene.

Note:

• Since it isn't possible to apply CGA rules to static models use Shapes instead. Static models are imported from formats such as OBJ, DAE, FBX, glTF, USD, and KMZ/KML.
• After importing, static models are linked to the source file. Consequently, renaming or moving the source file breaks the reference in the scene. In this case CityEngine replaces the missing model with a white generic cube. Select it and check the entry Asset_file in the Inspector to fix the reference.

Place a static model

A static model can be positioned and scaled as you wish within the scene by the means of the Move Tool (W) , Scale Tool (E), and the Rotate Tool (R).

The origin of the model is centered and bottom-aligned (except for KML import). This can be changed in the Inspector.

Move, Scale, Rotate Tools. Note the bottom-aligned point of attack / origin of the tools.

Settings in the Inspector

As static models are referenced only, the adjustments made here are not be saved in source data. The settings are saved in the scene and re applied to the source when reopening the scene.

Asset_File	Location of the asset in the workspace. Especially useful in case the reference to asset got broken.
Material_Colorize	Colors the model to increase visibility of an object in the scene. Setting it to white (#ffffff) turns tinting off.
Material_Transparency	Control the transparency of the model.
Mesh	Cleans up and reduces the geometry. It can help to improve the frame rate in the viewport.
Normals	Control the shading of the model. Choose between all soft or all hard edges in the model. Auto determines the hardness of an edge based on the angle between the adjacent faces and the hardness of adjacent edges. By default, the settings as defined in the source data are (keep original).
Pos_Bottom_Align	Places the origin of the model to the bottom or to the center of the model.
Pos_Center	Places the origin of the model to the center or to location as it is defined in the source file. If Pos_Bottom_Align is set, the vertical center is overridden (default, except fot KML import).
Pos_zUp	Some models are created in a z-up coordinate system instead of the CityEngine y-up system. Use this switch in order to correct this.

Align static models to a terrain

Static models alignment is a tool to align static models to arbitrary terrains (map layers with attribute "elevation" defined) or to the y=0 level. All currently selected static models and all static models of the selected layers are aligned.

1. Select the models you would like to align to a terrain
2. Click Layer > Align Static Models to Terrain...

Parameters

Heightmap	The terrain to align the shapes to. All terrain layers and attribute layers with attribute named "elevation" are listed here.
Offset	Specifies how far the model is placed above or below after alignment.

Note:

The model is not draped onto the terrain. The point of origin only is placed exactly onto the terrain (offset not included). Therefore other parts of the model might disappear in the terrain or hover above it.
