Text is considered a special Curve type that is completely separate from any of the other Curve types. Not only does the Font system have its own built-in font but it can use external fonts too, including PostScript Type 1, OpenType and TrueType fonts.
Textures are laid on top of materials to give them complicated colors and other effects. An object is covered with a material, which might contain several textures.
Having said everything about Textures in Blender in the previous tutorials, many people find it still hard to grasp the concepts behind the texturing system and applying textures.
Not only can textures affect the color of a material, they can also affect many of the other properties of a material. The different aspects of a material that a texture influences are controlled in the Map To panel.
This Blender tutorial teaches you how to make a Heads up display that will display your score. It will also show you how to make it so that that score increases when you collect a certain object.
