If you are into such noble pursuits as geo-modeling or photo-realistic rendering, there's a good chance that you spend a ridiculous amount of time hunting for photo-textures online. John Pacyga, apparently posted a long list of his favorite texture sources -- for both SketchUp and Photoshop. Some them are free, some have Creative Commons licenses, and some cost money, but all are worth browsing.
Pacyga writes, "Most of these sites offer free seamless textures that can be used in SketchUp (Import -> image) and into Photoshop (Edit->Define Pattern). There are too many textures to even count, so be selective! You are going to need a bigger hard drive… enjoy!"
Here are some links to textures:
- Patrick Hoesly Flickr Gallery
- Sketchup Texture
- Download 2GB of textures
- Filter Library (8293 Filters)
(Go to the tab: All Filters by Category, Filter Forge program lets you build filters to make may textures)
If you have found a seamless texture (one that can repeat attractively when you paint it on a surface), here is how you load it into SketchUp:
Update: Added two new resources -- one for textures embedded below and second a YouTube tutorial on textures:
