Materials and Textures
Material Bonus Packs from SketchUp 6 which used to be offered as downloads from the SketchUp site. And more Material bonus packs on the 3D Warehouse from other contributors. Instructions on downloading 12 at a time via the Component browser within SketchUp. Colors and Materials tutorial and instructions on using your treasure trove of textures inside SketchUp.
Take care when adding materials from 3rd-party sites. The file size may need to be optimized - down-sampled - as image files can be very large. Many image editors can do that through the menu option File > Save for Web (for example, a solid color material could be down-sized to a 1-by-1 pixel.) Also, some SketchUp plugins can also shrink material file size too, scroll down this section for links.
The following texture links go to sites with downloadable texture images. Save the images in folders somewhere on your hard drive. Then used the SketchUp plugin, massmaterialimporter, to create SKM material collections for SketchUp. Tutorial by Digital Thumb
SketchUp also allows you to drag-and-drop supported image types into an active SketchUp workspace from an open folder or browser window. Select the image, right-click to open the context menu, and select Explode to convert the image into a material that can be painted on models or added to a material collection. NOTE: If you drag-and-drop several images into SketchUp and the images overlap, those images may be 'glued' together. Unglue the affected images by selecting the image > right-click and choose Unglue from the context menu.
Turn your new materials into a favorite collection you can access from the Material browser inside SketchUp. Instructions.
Convert your raster image into a vector outline with WinTopo Free. (That file can be imported into SketchUp with one of the DXF plugins listed in the plugin section if you use SketchUp Make.)
