Modeling with Projected Textures in SketchUp
Follow these steps to get the hang of working with projected textures in SketchUp (and see the steps in action in the figure that follows):
Make a basic rectangular box and then apply a photo texture to one of the side faces.
Right-click the textured face and choose Texture→Projected from the context menu.
Make sure that Projected has a check mark next to it.
Draw a rectangle on the textured face and push/pull it inward.
Notice the stretched pixels effect?
(Optional) Add other angles or features to your model.
In the figure, an angled face is created.
Switch to the Paint Bucket tool, hold down the Alt key (Command on a Mac), and click somewhere on the textured face to sample the texture. (Your cursor looks like an eyedropper when you do this.)
This step loads your Paint Bucket with the projected texture.
Release the Alt (Command) key to switch back to the Paint Bucket cursor and then click the angled face once to paint it with the projected texture.
You see the stretched pixels effect here, too.
