Hi
It seems when exporting Houdini splines into Unreal, the translation is incorrect:

Unreal:

Houdini:

Hi! @Christy-892, could you please provide an HDA which I can replicate this issue from?
I've tested the he_example_spline_output.hda again, but does not see this issue.
So I need a way to replicate this issue @Christy-892.

[Christy-892]

Sure thing. I've sent an HDA via email as I was unable to upload that file type here. I created a much simpler example:

Hey @AdrianPanGithub - thanks for investigating. I do find this odd as it works fine for me when using the official HoudiniEngineForUnreal.

Hi! @Christy-892,
Wow, Really? That's so weird! Thank you for pointing it out.
May I ask:

• Which houdini version you are testing with Official HoudiniEngine?
• Are you using houdini indie?

[Christy-892]

Currently using:

• Houdini Indie 21.0.559
• Unreal Engine 5.7.0

Hi! @Christy-892,
Sorry that I need some time to figure out why.
I'm using the same version, just FX license, failed to get your hda work with Official HE,
Even the limited commercial version of my own hda also cannot work.
Only my full commercial hda can run properly with official HE,
So unfortunately, I cannot test it on my computer.

As your hda do can run in HE with Houdini Indie on your computer,
I guess maybe the Official HE has come special code for indie license, and I'll try to find it in the future,
But sorry that I cannot fix it recently, so I will leave this issue open until I know how to fix it

If Someone has the houdini indie license, please help!

Here are the .hda and .hdalc for test:
