This paper deals with the topis od modeling modular kits to create a scene for a video game. The theoretical side of the paper id based on explaining 3D modeling. The focus is on 3D modeling techniques, techniques behind the modular level design, and the principals of a game engine. The Paper is based on 3D modeling in „Blender“ software since all of the 3D work is done in that software. The theoretical side of the paper is a brief explanation of the game engine „Unreal Engine 4“because the final scene is created with the help od that engine. The practical part of the paper is based on the creation of modular kits and game assets with the help of the „Blender“ software for 3D modeling, which tools and principles of modeling are described in the theoretical part of the paper. The practical part of the paper also briefly show the texturing process of a 3D model and level creation with the help of „Unreal Engine 4“.
