Export Splines between Houdini and Unreal
Gamedev

This project demonstrates how to import and export splines between Houdini and Unreal Engine using JSON files. With the Labs Unreal Spline SOP (Beta) and the SideFX Labs Unreal Plugin, you can now easily send splines between Houdini and Unreal Engine—even without Houdini Engine for Unreal.

This workflow supports live editing and I/O of single and multiple splines, splines inside an Unreal Blueprint, splitting splines from one Blueprint into multiple Actors, using splines with PCG, and exporting splines with tags to drive PCG-based mesh instancing.
