UNITY-3D Course

Unity 3D

An incomplete (in-progress) course about Unity 3D. This is listing what I only used in 3D.


A mesh is something that we will send to the graphic card, containing information about what the graphic card will have to render. This is ways more complicated than this, it's well explained here if you want. At this point, what's a mesh is not important 🧐, but every 3D game object will have two components

  • a Mesh filter: tell which mesh should be rendered (ex: cube, cylinder, or your custom mesh/3D models from Blender 😎)
  • a Mesh renderer: tell how to render a mesh
    • Apply a material (see the next section)
    • Lightning
    • ...


This is a sort of skin/texture for our 3D models.

Create a material
  • In the Project window
  • [Optional] In a folder called "Materials"
  • Right-click > Create > Material
  • [Optional] you may set the material as Transparent, if you are planning to make the applied game object a light source (trick)
  • [Up to you] you can change the color on the line "Albedo"
  • [Up to you] you can set the smoothness to 0 (=not shinny)
  • [Up to you] you can set an image (=texture) by clicking on the little circle with a dot inside, right before "Albedo"
  • [Up to you] you can enable emission and set a color, if you want this color to be emitted from your material (trick)
Apply a material
  • Method 1 πŸ“š
    • Click on a Game object
    • Mesh Renderer > Materials
    • Drag and drop your Material from the Project window to the input field
  • Method 2 πŸš€
    • Drag and drop the material on the game object, in the scene window
  • Method 3 πŸš€πŸš€
    • Drag and drop the material on the game object, in the hierarchy window
