Rendering Tip - Use images and textures for faster rendering
Use images and textures for faster rendering
SketchUp, and most renderers, do an excellent job rendering images and texture materials.
For background objects, and other objects for which 3D detail is not important, use images instead.
There is a free plugin for SketchUp - RpTreeMaker - which can be used to create tree images which can speed up your rendering time.
