Some of the models might not be in FBX format, but you can open them up with Blender (or 3dsMax/Maya etc) and then export them out as FBX files. TurboSquid (sort the products by price and you will find many free ones) - :/// Check your Unreal Engine 4 version, and download the compatible Character Creator & iClone Auto Setup to automate.I highly recommend looking through the above examples, a lot of great content. .eate your own game or real time animations using this model using the unreal editor and unreal engine packaged along with ut2003.

Animation Starter Pack - a bunch of animations you can use for characters, can be re-targeted to the Mixamo pack.Mixamo Character Pack - 15 free characters with some animations ready to be used.Each of the sample game contains a lot of assets (meshes, materials, textures, sounds and more).

First place I would look is in the Learn tab and Marketplace tab of the Launcher, there are quite a few free projects and examples that include a LOT of content, plus you are free to use any of these assets in a commercially released game.
