The plugin supports the import and export of Data Layer information to and from Houdini. This functionality is avaiable in Unreal 5.2 and later.

Data Layers are avaiable in Open World Maps that use World Partition.

In Houdini, Unreal Data Layers are represented by groups with the prefix unreal_data_layer_. For example, if an input belongs to data layer called Objects then a group will be created on the input for the HDA called unreal_data_layer_Objects.

When you ouput data from an HDA to Unreal any groups that begin with unreal_data_layer_, it assigns outputs to a layer during baking. Only actors directly created by Houdini will be assigned to data layers. Implicit actors, such as foliage, are not assigned to layers.

By default new Data Layers will not be created, setting the attribute unreal_create_data_layers to 1 will cause a new data layer to be added to the world and a new Data Layer Asset created in the Bake Folder.
