Hi, so for a uni assessment we have made our own level in unreal engine 4
we have made fish and butterflies for the level but do not know how to setup a blueprint to get them to just move around a path so it looks like they are doing something, we’ve tried some AI tutorials but all of these use the base character that’s already in unreal and none of them have worked for our models, the models have a basic animation already set up for them with a skeleton mesh we just want to know the easiest way to get them moving around.
Thanks! 
you could try taking a look at one of the example projects from epic, I cant remember witch example it was (I think it was the “content example” project) but one of them had an AI controlled butterfly that flies around a tree.
