Unreal 5.5 March 16, 2026, 12:46 p.m.
Hi, sorry for the confusion, this is how the plugin used to need to be installed. It is now project based, which allows for more flexibility with teams with different projects and Unreal/Houdini versions. So you could grab the 'HoudiniEngine' folder in 5.6 and copy it into your projects Plugin folder. You can make the folder if it doesn't exist.
Example location "../Documents/Unrealprojects/MyProject/Plugins/**HoudiniEngine**" or wherever your project lives. Then reopen the project and give it a shot. I think that will do the trick.

Beginner question: How can I expose the spline component? March 13, 2026, 1:57 p.m.
The curves sop inside an HDA is a deprecated workflow.
You will need to provide the HDA curves from Unreal using splines in your level. So in Houdini the curve would live upstream and plug into the HDA input.
Then in Unreal, you change your HDA Input to either 'World' if you are using curves from your level. Then select those curves as the input for your HDA. Or you can set the HDA Input to 'Curve', and Houdini Engine provides a base curve you can edit directly in the detail panel as well.
We have some basic set ups for curves in our content examples if you wanted to download and check it out. https://github.com/sideeffects/HoudiniEngineForUnreal-ContentExamples [github.com]
