What version of Unreal do your kits support?

Our 4.0 kits will work with Unreal Engine version 4.25 and above.


If you're using an older version of the engine, you will need to use our FBX files, import them into your scene, and reconnect all texture maps to your materials manually. This is a significant amount of work and we recommend upgrading to the latest version of Unreal and using our native UE4 files if possible.

How do I open the Unreal Kit?

If you've downloaded the Unreal Native files from KitBash3d.com, the zip file will contain a .UProject file. Double click that file to open the scene. Please note that the first time you launch a kit in Unreal, it may take some time for Unreal to process and build all the textures, materials and geometry.

**If you are referencing this article for the DMZ kit, please see our DMZ help article to learn about improvements to the way we deliver files for Unreal and Unity.**

How do I import the Unreal Kit into an existing project?

If you've downloaded the Unreal Native files, the zip file will contain a Content folder. You can copy all the files within the content folder into your existing project. The next time you open your project, the kit will be in your Content Browser.

Why is my scene empty?

In order to speed up load times, we do not have all of the assets of a kit laid out in a scene. Instead all of the assets will be in your Content Browser when you open a kit in Unreal.

How do I modify Actors?

The assets in our Kits are setup as actors in order to make them easily customizable. If you double click on an Actor, you will open the editor. In here, you will see a list of "StaticMeshes" as components. You can move and edit these components to customize an Actor. Please note that any adjustments to an Actor will affect all instances of that Actor in your Scene.

How do I setup Collisions?

All of our kits will import as Actors and Static Meshes in Unreal. If you'd like to add collision to a piece in order to do things like walk on top of a ground, or run into a wall, you can easily add collision to any pieces. We recommend not adding Collision to everything as it will significantly slow down the performance of Unreal and increase file size.



How do I disable Collisions?

To remove or disable the collision to an object (work only for individual staticmesh” and not for The full “Actors” you will have to do this for every asset that you need to remove the collision: Select the object “staticMesh”in the level, look in the details panel under Collision> Collision Presets > NoCollision.

How to change the UV channel :

How to change the UV channel: Select the Mesh | double click, it will open the editor mesh | go to the Detail panel, Under General Settings Click on the small arrow to show more option, And Under “ Light Map Coordinate Index” change the number 0 to 1
