Firstly, im using Houdini 21.0 and Unreal 5.6. I have a very rough and simple road creation tool and im trying to figure out how to expose the main curve in unreal as a spline component. Ive looked at documentation and all the videos I can, nothings really working. Ive reduced the complexity of the tool (as there was multiple curves being used) to one curve in hopes to just figure it out from one curve, but nothing yet. Ive used an attrubute wrangler to create an integer with the vex code, which in the documentation states that it will expose it as a spline component in unreal. Im not entirely sure where this attribute wrangler should be placed and anywhere ive placed it so far hasnt really done much. Following older youtube tutorials about curves from houdini to unreal has turned out to be no help as theyre outdated.

Anyone with any knowledge on how to set up an editable curve from houdini to unreal that could drop some knowledge on me. would be extremely appreciated.

(Im new to houdini, I started about a week ago. Ive gone through a lot of the tutorials on the sidefx website. Again, most are slightly outdated for these workflows.)
