I’ve never written a custom animation node myself, but glancing and the source it looks like it’s supposed to have an in-editor part based on UAnimGraphNode_Base, and a runtime part based on FAnimNode_Base. So you should have two modules, one for the editor and one for the runtime.
We create plugin with custom AnimNode. Project is runing and building correctly. But after shipping we got this error Screenshot - 554e67490583acdef8472c4d35dc1895 - Gyazo
Plugin Module Type set to Editor.
If we set Plugin Module as Runtime we cann’t build project becouse anim node using Editor classes (UnrealEd.h(54)…).
If we create Editor Module instead we got the same error with Linker, like in first case.
So, anybody have and idea what are we doing wrong?
Thank you! I’ll try it right now!
We devide our plugin into two parts and i think are on the right way. But now we have
error LNK2019: unresolved external symbol
while building editor.
Unfortunately I’m not omniscient, so if you want me to help you’ll need to provide the full error description.
Of course, thanks for your help! Here it is:

You need to export your FAnimNode_WeaponReduction class from the module like so:
class AI_FLY_API FAnimNode_WeaponReduction
And add the module that contains FAnimNode_WeaponReduction to PrivateDependencyModules in the Build.cs of the module that contains your UAnimGraphNode_WeaponReduction.
Edit: Actually AI_FLY_API should match the module name, so it’d be something like YOURMODULE_API.
It is help! Now shipping failed:

We set Runtime Plugin Module as PreDefault (as mentioned here A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums) and everything builds successfully.
