Adding Textures and Colors
About surface textures and colors
In an Atmosphere world, you can add textures and colors to the objects you create to make 
them look as real (or unreal) as you want. Applying a texture adds a 2D image to the 
surface of a 3D object, giving the appearance that the object is composed of the material 
in the texture image. Applying an RGB value creates a solid-colored object.
Before and after applying a surface textures in Browser view. 
Creating surface textures
A surface texture can be any image that is saved in a GIF, JPEG, or PNG file. It can be a 
scanned photograph or a bitmap image created inside a graphics application such as 
Adobe Photoshop. When you apply a texture to a surface, Atmosphere Builder tiles the 
texture using the scale and rotation values that you specify. Tiling is the process of 
repeating a texture to fill up a surface area. Tiling in Atmosphere Builder uses the same 
concept of tiling in the real world, where tiles are placed edge-to-edge until they fill the 
desired area.
How you plan to use a surface texture will determine the characteristics of the source image:
If you’re creating a texture that will be tiled, keep the image size and file size small, and 
try to create a seamless texture. A seamless texture is an image whose top edge precisely 
matches its bottom edge, and whose left edge matches its right edge. When the texture is 
tiled on a surface, no seam is visible between tiles. There are different techniques for 
creating seamless textures. For example, you can use the cloning brush in Photoshop to 
create a seamless texture. Refer to your image editing application’s documentation for 
more information.
