Procedural Spline generator from Houdini to Unreal Oct. 4, 2019, 2:14 a.m.

Wow. Thanks for putting that together!

So I could try it in UE4, I separated the circle & point jitter and referenced that with an object merge. Works perfect with the Unreal Spline!

It's gonna take me a little bit to fully dissect what you're doing in the point wrangles.

Really appreciate you posting the hip file. Thanks!

Almost got it. My stupid problem was with selecting the BP (“Start Selection (Locks Details Panel)”; “Use Current Selection(Unlocks Details Panel)”).

I'm close, but now I've discovered a new problem. When I try using the Unreal BP Spline, I get weird results when I translate to the side, Y. If I keep the spline in XZ coordinates it works great. I added a switch to my HDA so I can switch between the unreal spline and my internal Houdini curve. When I try using my Houdini Curve, it works perfect with none of the issues of the unreal spline when translating to the side. Any ideas?

Thanks for you help!

Hi. I can't seem to get this working; I can't attach a BP (with spline component) to the HDA (with object merge node).

In Houdini, in my HDA, I have object merge node feeding into my graph. I dragged “Object 1” from the object merge into Type Properties. In Channels tab of the parameter now has “object_merge1/objpath1”. Apply,Accept. Save Node Type, Match Current Definition.

In Unreal, I select my imported HDA and Rebuild All Instances. I now have an input parameter that can be: Geometry Input, Asset Input, Curve Input, Landscape Input, World Outliner Input, Skeletal Mesh Input. No matter which I choose, I can't select my CharacterSplinePath BP (which contains a simple Spline Component created from Add Component, and I checked Editable when Inherited). What Input setting does it need to be to use the blueprint?

Probably something stupid that I'm missing, but I can't figure this out.

Thanks in advance!
