Reparameterized texture using Low Distortion (left) and Fewer Seams (right)
4
(Optional) If the reparameterization option you chose does not create optimal surface coverage, choose Edit >
Undo and try the other option.
You can also use the Reparameterize command to improve the default texture mapping that occurs when you create
3D models from 2D layers. See “
Create 3D objects from 2D images (Photoshop Extended)
Create a tile for a repeating texture
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.
Paint on 3D models (Photoshop Extended)
You can use any Photoshop painting tools to paint directly on a 3D model just as you would on a 2D layer. Use
selection tools to target specific model areas or let Photoshop identify and highlight paintable areas. 3D menu
commands let you clear away areas of a model to access interior or hidden portions for painting.
