It started out as a research project at Esri R&D Zurich to get to a tighter integration of CityEngine and Houdini than just via file-based import/export of assets. Palladio has been invented by Matthias Buehler and Simon Haegler in early 2015. Our thanks also go to the fine folks at Esri R&D Zurich and vrbn studios which provided valuable comments and feedback. Anyone is invited to submit issues and/or to fork and contribute to this project. Our goal is to bring as many Houdini and CityEngine users and developers on board as possible. Matthias is focusing on UX/UI topics and use-cases, while Simon is focusing on the implementation and procedural modelling technology. Palladio is maintained as an open-source project by Matthias Buehler ( vrbn studios) and Simon Haegler (Esri R&D Zurich).

HOUDINI_DSO_ERROR: useful to debug loading issues, see.

Valid values are "debug", "info", "warning", "error", "fatal"

CITYENGINE_LOG_LEVEL: controls the global (minimal) log level for all assign and generate nodes.

If you use $HIP to refer to the RPK in the pldAssign node, your Houdini project will stay relocatable. It can be useful to put RPKs into an rpk sub-directory of your current Houdini project. Keep CityEngine Rule Packages in the Houdini Project

Export the shapes to Alembic, the two report values are now attached as user properties to the meshes.

The seed rule attribute should have been connected to the previously assigned seed object attribute.

Run the following Python script on your scene objects to assign the random seed as object attributes:.

This short CityEngine guide explains how to include the random seed and start rule assignments when exporting input geometry to Alembic. Tips and Tricks How to export an Alembic from CityEngine as input to Palladio Please refer to the licensing section below for more detailed licensing information.

Commercial use requires at least one commercial license of the latest CityEngine version installed in the organization. the rich CityEngine toolset to design a city from scratch (or based on geographic data) is still needed. Palladio does not include the city layouting and street network editing tools of CityEngine i.e. However, Palladio is restricted to the procedural generation of single buildings / objects.

Palladio is well suited for managing the procedural generation of architectural 3D content in digital sets. Comprehensive RPK examples are available below and can be used “out-of-the-box” in Palladio. An RPK includes assets and a CGA rule file which encodes an architectural style. Palladio requires so-called rule packages (RPK) as input, which are authored in CityEngine.

Consequently, the 3D environment artist can change the height, style and appearance of buildings easily with a parametric interface at any point during production. The buildings stay procedural during the entire modeling workflow (optionally even at render time). Complicated export-import pipelines are no longer needed, which also means that the procedural building models do not need to be “baked” anymore. Therefore, a 3D environment artist does not have to leave their familiar Houdini toolset anymore to make use of CityEngine’s procedural modeling power. It provides operator nodes which enable the execution of CityEngine ‘rules’ within Houdini networks.
