    Well I'm feeling pretty stupid. What I want is to drop in rats, and have them just run around in random paths.
    I tried this:
    "First be sure you have a navmesh volume in your level.
    Next drag some "Rodent_Path_Nodes" around your level where you want the animals roaming around.
    Then drag in some animal NPC blueprints into your level (BP_NPC_Rabbit, BP_NPC_Rat, BP_NPC_Squirrel)
    Next Build Navigation."

    That just had the rats stand there. Is there a way to do what I want explaining to a dummy like me?

      Make sure the ground nodes are not too close together- at least 4000 Unreal units apart, and build navigation. Give it a try.

          Another question, after reaching a ground node, can the rats then switch to another node to keep on moving continuously? Also they are walking, is there a way to make them run faster?

            Open the Rat folder and then in the AI folder- open the Behavior Tree (Rat_BT)
            In the Patrol section of the behavior tree you can disconnect the wait nodes- so they don't stop between node changes. Also in the same section you can set the Min and Max Walk Speed. Bump those numbers up to get them running.

                I was very excited to get started learning Unreal Engine. (last January) I was amazed at how much free stuff was available in the marketplace, as well as tutorials and YouTube videos to get me up and running. I was hesitant to start buying content until I got a handle on everything...well, as much as possible.

                I have easily been able to follow tutorials, and make progress learning how to make environments. I wanted to populate my fields and woods with animals, the skies with birds, the lakes with fish, etc. So the first product I bought from the store was this Small Animal Pack....about 4 months ago.

                Unfortunately, it's been extremely frustrating and disappointing since then. I'm quite certain an experienced UE user can figure it out, however, I'm apparently not there yet. Without a beginning-to-end tutorial to follow, I have no idea where to begin to fix problems that crop up. I can follow a tutorial on blueprints, and get results. But being told to throw things in a level doesn't work.

                "First be sure you have a navmesh volume in your level.
                Next drag some "Rodent_Path_Nodes" around your level where you want the animals roaming around.
                Then drag in some animal NPC blueprints into your level (BP_NPC_Rabbit, BP_NPC_Rat, BP_NPC_Squirrel)
                Next Build Navigation."

                This is pretty meaningless to a noob.

                Can anyone shed any light HOW these things are supposed to be done correctly? I still have deer, bear, cattle, pigs, boar, chickens, hawks, eagles, trout, scorpions, snails and frogs to animate. I was hoping to make them all react and run away like the rabbits, rats and squirrels in this pack.

                Thx...

                    This is really cool! I'm running this in an VR for OculusGo experiment and it's looking super cool. My question is: all of the animals seem to be running as soon as I start the level. Is there a proximity threshold that could be set to activate them when the player reaches a certain distance from them?

                      Hi, I'm wondering how to actually apply damage to the animals? Thanks

                        Open the AI Controller and select AIPerception and in the Sight section you can reduce the Sight Radius to whatever you like.

                        Look for "Event Any Damage" in the "BP_NPC_Rodent_Base" Blueprint in the "ParentClassBlueprints" Folder.

                        And on the Damage dealing side of things, look at the "ThirdPersonProjectile" Blueprint found in the (ThirdPersonBP> Blueprints) folder. In the event graph look for OnComponentHit.

                        Open the "BTTask_Rodent_Random_MaxWalkSpeed" Task. It's in the "ParentClassBlueprints" Folder. The "Tasks" sub folder

                          Hi, and thanks for your help on Youtube.

                          You said, "You need to open the Rodents demo level, then when there, right click on the Rodents Folder and select Migrate, then select Ok, then select your games content folder and then click "Select Folder" now the Rodents folder will be in your games content folder."

                          I'm not seeing a Demo level, unless you mean the Overview Level, which is the default level that opens when UE4 starts. I've tried several times using the Overview level. The Rodents folder shows up in Explorer, but doesn't show up in the Content Folder in UE4.

                            Yes I mean the overview level.
                            This is what it should look like when you open the overview level.In the lower left. The Rodents folder, that's the folder you want to migrate.

                              Yep, that's what I've been doing. Getting a message saying "362 files copied. Some files could not be copied."

                                Ok now when you open your level do you see the Rodents folder?
                                I have just tested this in 4.25, it is working.
