Houdini Engine Issues with Curves in Unity

Hello, I am using Unity 2018.3 and Houdini 17. I have an issue with Houdini Engine in Unity when I use curves in my tools. I created a tool to generate path that affect Terrain height (like in Unreal).
But when I import my HDA There is an issue with my curve, "System.FormatException: Input string was not in a correct format".
I followed The Houdini Engine Documentation for Unity to create it.
And If I import my tool in Unreal engine everything works fine, I can see my terrain in the viewport and edit the curve.

So I would like to know if someone has an idea on how to resolve this issue ? ^^
Thanks for your help.

Hi, I have exactly the same issue since today.
Unity 2018.3.6f1, houdini 17.0.460
Yesterday, everything was working fine. I just updated HDRP to 4.10, but I don't see why it would be related.

 

Ok I fixed it by installing the latest Houdini version AND the latest Unity one. However, the readmes don't explain what changed around HEU_Curve.

 

Well, The error is back. Very strange.

 

Yes, that's a very strange issue ^^. My project was not in HDRP and it never worked for me :/
And I also have the same versions of Houdini and Unity. I also tried to change to older version (2018.3.2 and 17.0.352) but the error stay too :/

Next week I will try it at school with my teacher, I will see if they know how to resolve it

 

As it's a string to float conversion error, it may be related to environment culture. However, Unity seems to lock the enviro culture to US-us, so I don't get why it throws an error.

 

Ok here's my fix: I forced the culture environment in the HEngine script itself.

 

OMG Thank you it works ! thank you

 

Thank you, do you know if it has been fixed ?

 

@Dieedi
A bit late but... yes it did. The fix was added into a daily build a few days after, and several production build were released since then.

 

Question : did you guys have to buy the Houdini Commercial license, in order to use it ? The free version does not seem to work. Getting a lot of errors when setting it up in Unity.
