Is the Houdini Unreal Engine Plugin free to build? We are working from a custom build and would basically need to build Houdini Engine when we change versions.

Thanks

Hi,

Yes, you need a HoudiniEngine license to use the tools, but no need to pay anything for building the plugin as it's open source.

You can get the source either from the engine/unreal/4.2X folder in your houdini install directory,
or from our github repository:
