Some small parts of my daily-used houdini accessories for making real-time procedural city and terrain tools.

All of them support unreal 5.5 - 5.3 and later, and all builds of Houdini 20.5.
And if you encounter any issue, please report on GitHub, So I’ll see it.

Also thanks for the advice and bug reports from VFX-沐月 and inspirations from _smile滴水C long long ago.

Seamless Integration between Houdini Engine and Unreal Mass Zone Graph.
Support both Zone Shape Input and Output
Support Unreal 5.3, 5.4 or later, and Houdini 20.5.278 or later.

And Unlike the citysample toolset, this zone graph translator plugin and rest other tools could Update in Real-Time in the unreal editor within a huge scale.
(Beware that only the unreal plugin is open-sourced)
