Autodesk FBX Export
"Autodesk FBX technology is one of the most widely used and supported platform-independent 3D data interchange solutions in the industry today. FBX plug-ins are included with Autodesk Maya and Autodesk 3ds Max software-providing high levels of interoperability between these packages - and with Autodesk MotionBuilder software, which supports FBX natively." -- Autodesk
CityEngine 2017.0 uses FBX 2017.0.1 (external link). CityEngine writes FBX files with the internal FBX file format 7.5.0.
Specific Export Options for FBX
The FBX exporter supports the following additional settings:
|Create Shape Groups||If enabled, a transformation node is inserted for each shape (i.e. building). Meshes will not be merged by material across shapes.|
|File Type||If set to binary, the file is stored in binary (native) format.|
|Embed Textures||If enabled, textures are stored inside the binary FBX file.|
CGA Mapping to FBX
As the FBX file format is quite verbose, we restrict ourselves to some selected examples for this manual. Please refer to the documentation provided by Autodesk (http://www.autodesk.com/products/fbx/overview).
Geometry and Transformation Data
Multi-Texturing and Layered Texture Nodes
If at least one texture is set, Autodesk Maya loses the diffuse color settings upon FBX import, the ambient color is retained.
Working with per-texture transformations
|CityEngine||FBX Import Autodesk Maya|
|The CityEngine features material attributes to scale, translate and rotate textures independently of the actual texture coordinates stored inside the assets:
||Upon FBX import into maya, CityEngine's tu and tv attributes are mapped to the "Offset" parameter of maya's place2dTexture nodes, su/sv are mapped to the "RepeatUV" parameter and rw is mapped to the "Rotate Frame" parameter.|
