What is buildings in 3D modeling mobile games?

In 3D modeling mobile games, buildings are virtual 3D structures that act as environmental, functional, or playable assets in the game world. Created with tools like Blender, they have texture, depth, and interactivity—such as decorable houses, shops for items, or fortresses to defend. Beginners can use free tools like Tinkercad to practice basic shapes and texturing, helping understand how these game elements are designed.
