Flat and Cubic Projection

The Flat and Cubic projection types are far less prone to being distorted than other projection types. The Flat projection type will project the material onto a surface as would a slide projector - flat. This makes it possible to project a material very accurately because the direction of the projection can be easily adapted to the angle of an object. As already mentioned, this projection type’s weakness lies therein that the projection can be distorted or blurred on curved surfaces. These effects can, though, be kept to a minimum. For example, take a look at the image below. The seats have been textured with the Tile material using a Flat projection. The projection plane was adjusted to match the angle of the seat backs. Although the texture is slightly distorted on the seat bottoms, this effect is far less bothersome than if the seats had been textured using a cylindrical projection type.

The more detailed a material’s pattern is, the less noticeable this distortion will be - for example the fine structure of a leather or cloth surface in relation to the size of the actual seats.

You should always keep in mind that the projection type in PLUGIN_CMD_12184> Texture Axis mode is an exact representation of the tiling of the material in the projection mode selected. If the tile’s aspect ratio is modified so it no longer reflects that of the images used in the material the material will appear distorted. In other words, if the material contains images with an aspect ration of 4:3, the texture tile’s aspect ratio should be the same.

The Cubic projection type is the same as the Flat projection type only that it projects the material onto a cube from six directions simultaneously. This type of projection is good for use on cube-shaped objects as well as objects whose shape is approximately that of a cube. This saves us from having to manually project a material flat onto six sides - although this can be done, if desired. After all, we are not restricted to applying only a single material to a given object. Combining multiple materials on a single object will be discussed later in this tutorial.
