A repeating texture is composed of identical tiles in a grid pattern. A repeating texture can provide more realistic surface coverage of the model,
use less storage, and improve rendering performance. You can convert any 2D file into a tiled painting. After previewing how multiple tiles interact
in the painting, you save one tile for use as a repeating texture.
To set up a mesh for a repeating texture, use the 3D application that created the model.
1. Open a 2D file.
2. Select one or more layers in the file, then choose 3D > New Tiled Painting.
The 2D file is converted to a 3D plane containing nine identical tiles of the original content. Image dimensions remain the same.
3. Edit the tiled texture with painting tools, filters, or other techniques. (Changes you make to one tile automatically appear in the others.)
4. Save a single tile as a 2D image: In the Materials section of the 3D panel, choose Open Texture from the Diffuse menu . Then choose
File > Save As, and specify a name, location, and format.
Unless you plan to use the original, nine-tile painting independently, close it without saving.
5. To load the tile as a repeating texture, open a 3D model file. In the Materials section of the 3D panel, choose Load Texture from the Diffuse
menu, and select the file you saved above.
