Importing 3D models into game engines

This article includes details on how to import 3D models created by Kenney into various game engines. Refer to the general section to find common tips.

General

• Refrain from using OBJ unless it's the only supported file format.
• FBX and GLB (glTF) files are equal in features but GLB is smaller in size.
• The glTF file format is distributed as GLB in Kenney game assets.

Common issues

Missing colors

Import the included textures and make sure the material in the game engine has the proper texture selected. Each asset pack requires its own texture(s).

Purple (magenta) models

There's an issue with the shader in your game engine, refer to the documentation or discussion boards for the game engine you're using.
