TypeLoadException: Could not load type 'Htc.Viveport.SDK.PlayObjectAnimations' from assembly

[Laugster]

Hello

Using Unity 2017.2

As we've imported ViveportSDK we had a lot of errors. We've fixed some, but this one is consistent: 

TypeLoadException: Could not load type 'Htc.Viveport.SDK.PlayObjectAnimations' from assembly 'ViveportSceneSdkLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
System.Reflection.MonoMethodInfo.GetMethodInfo (IntPtr handle) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MonoMethod.cs:59)
System.Reflection.MonoMethodInfo.GetAttributes (IntPtr handle) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MonoMethod.cs:75)
System.Reflection.MonoMethod.get_Attributes () (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MonoMethod.cs:245)
System.Reflection.MethodBase.get_IsSpecialName () (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MethodBase.cs:184)
UnityEditor.Build.BuildPipelineInterfaces.InitializeBuildCallbacks (BuildCallbacks findFlags) (at C:/buildslave/unity/build/Editor/Mono/BuildPipeline/BuildPipelineInterfaces.cs:191)

Any idea what this comes from?

Hi Laugster: 

Currently, only Unity 5.5.2f1 is supported. For your information. 

Please try the older version of Unity and have a try. Thanks.

Hi is this still the case right now in June 2018? Just starting on Unity development and running Unity 2018 and having the same error. 

 

Edit: Ah yes I can see at the top of the scene SDK tutorial it says so. Sorry disregard this post.
