Importing Images for Textures
Bring in the smallest image file resolution for the project to lessen the impact on file size and moving through the model.
- An application like Google Earth can get upset with excessive large image sizes.
- While smaller is 'better', the maximum image size is 1024 pixels wide x 1024 pixels high. If a modeling situation requires a higher resolution, cut up the large image in an image editor, Import in the smaller sections and reassemble.
- If you import images into your model, use JPG images rather than TIFF images. TIFF images tend to have large file sizes and take more computing resources to display.
- PNG or JPEG files best for textures?
- An image editor like Adobe Photoshop, Photoshop Elements, Gimp, and CorelDraw can readily resize images. TIP: Try using File > Save for Web to optimize the saved file size. Unless you are working on a model for a high-resolution image export, this is a place to help reduce your SKP file size.
- If there's a quality option on saving a particular image extension, like JPG, choose high quality.
- One of the easiest ways to view/resize an image file on a PC is to use IrfanView. It's a free, quick-loading, multi-lingual, powerful media viewer/editor that's also easy to use. In IrfanView go to Image > Resize/Resample. BUT, if you are using PNGs with any transparency, the transparency may not be saved unless the PNG transparency options are selected. If using a different, free image viewer, check for something similar.
Some notes on tiling texture
Viva La Difference!
Wolfgang (aka VAM) created this original small, wire mesh tile from a linked JPG image given by Mark (aka Woodburyboy)
in his forum
inquiry. Courtesy of them, you too can compare the effect material size has on your SketchUp model - and add a gorgeous new material to your collection.
CLICK on the images to get a full-sized version. Then right-click on the image to download. Then import the image into SketchUp to make it into a texture.
The test: Open a new session of SketchUp. Import the first image. Paint it on a rectangle. Save the model. Do the same thing with the second texture. The SKP file size of a single face painted with the larger fence grid will be nearly doubled the file size of the same sized face painted with the single tile.
(Right-clicking on these thumbnail images will save even smaller copies. Although there is not a clean transition between the transparent and colored region. Using a thumbnail image as a SketchUp material could produce an unpleasant white outline artifact around each tile.)
- Import the smallest image for tiling textures, which again is to minimize the imported file size.
- Granted, more complex textures, like cobblestone, may need larger tile images to look better. But try to minimize texture size wherever possible.
- Some online texture resources and tutorials on making your own tiling textures in a photo editing program are located over on the Resources page, Materials and Textures section. xx
