Hi there!

I installed Houdini Engine and im getting some nasty error (First Time). i never saw those error before so appreciate any advice.

Unreal Version 4.26.2

Houdini engine versions I tried:
4.24
4.24 v2
4.25
2.25 v2

Houdini: 18.5.351

When i try to open the project it say:
Missing Houdini Modules
-HoudiniEngineRuntime
-HoudiniEngineEditor

if i rebuild it throw an error, i should build from VS.

From VS i get the follow errors:
Severity Code Description Project File Line Suppression State
Error LNK2019 unresolved external symbol "__declspec(dllimport) private: static class UClass * __cdecl UPhysicalMaterial::GetPrivateStaticClass(void)" (__imp_?GetPrivateStaticClass@UPhysicalMaterial@@CAPEAVUClass@@XZ) referenced in function "public: static bool __cdecl FHoudiniEngineMaterialUtils::UpdateMaterialInstanceParameter(struct UGenericAttribute,class UMaterialInstanceConstant *,struct FHoudiniCookParams &)" (?UpdateMaterialInstanceParameter@FHoudiniEngineMaterialUtils@@SA_NUUGenericAttribute@@PEAVUMaterialInstanceConstant@@AEAUFHoudiniCookParams@@@Z) Houdini C:\UnrealProjects\Houdini\Intermediate\ProjectFiles\Module.HoudiniEngineRuntime.3_of_4.cpp.obj 1

Did you add the plugin to your project/plugins or to the UE4/Engine/Plugins?

If added to Project/Plugins, be sure to right-click uproject and "Regenerate Project Files".

Hi,

You're working with Unreal 4.26 but are using either a 4.24/4.25 versions of the plugin.
That's likely because the build of Houdini you're using was released before UE4.26 was released.
The error you're getting is expected, as the binaries of the plugin you're using were not build for UE4.26.

The easiest solution would be to simply install a more recent version of Houdini 18.5, that will have the 4.26 plugin.
Also, don't install the version 1 plugin, as it's now deprecated, you'll want to use the plugin that will be in the 4.26-v2 folder.
