I make the models in Blender, I started by hard surface modeling and later moved to organic bodies. I made chairs, piano, portraits in library's gallery, trees, walkways, rocks, pond, lake, temple, light pole. I take pictures myself to create textures, I view them many times in Unity to apply bump maps and varied lighting. I need to learn more modeling for animals and rigging animated characters, but I also made flags which wave with the wind.
The good thing about making game in campus is that the context is authentic. I can live inside it everyday and observe to replicate the real environment.
