| Since | 20.0 |
This node exports 2 CSV files that are plugged into the Houdini Import DataTable Blueprint inside a PCG graph in Unreal Engine 5.2 and up. It can export attributes such as Positions, Rotation, Scale, Mesh, Material and Custom ones. These attributes are then read inside the Unreal Blueprint to reproduce the Copy to Points node functionality with a piece attribute that decides what mesh should be copied to what point.
Warning
Make sure to have the Procedural Content Generation Framework (PCG) Plugin enabled.
Make sure to have the Procedural Content Generation Framework External Data Interop Plugin enabled in order to use the Alembic node (Only available in UE5.4+).
The Unreal Engine Houdini Import DataTable Blueprint needs to be fixed once it is downloaded as part of the SideFX Labs Unreal Plugin.
When opening the Houdini Import DataTable Blueprint for the first time, Unreal may not be able to find the node called Break CSV Point Format. (This is likely a known issue on the Unreal side.) All you have to do in that case is to recreate it and rewire it to the other nodes.
In case the Break CSV Point Format node does not exist in the search, you can copy and paste the content from the text file “Break CSV Point Format node as text.txt” into the Houdini Import DataTable Blueprint to recreate the node.
