Hey guys, I'am iported a HDA.

The HDA is a simple Box.
Whats wrong?

“Defined version: 3.3.api:2 vs Running version: 3.3.api:3 mismatch. libHAPIL.dll was loaded, but has wrong version. No cooking / instantiation will take place.”


- Unreal Engine 4 Version: 4.24.3
- Hoidini Version: 18.0.416
- Houdini Engine is active.

Hi,

The version of the plugin you're running was built for Houdini 18.0.391, which uses HAPI3.3.2.
The version of Houdini you have installed (H18.0.416) is using a more recent version of Houdini Engine (HAPI3.3.3)

You should update the unreal plugin with the one that ships with H18.0.416.
We only require updates like that when the Houdini Engine API version changes.

You can do that manually by going to Houdini 18.0.416's install folder, engine/unreal/4.24 and copy the HoudiniEngine folder to your UE4's Engine/Plugins/Runtime folder.

Ah ok, I got it. thanks a lot.
