How to Edit Pixels in a Texture Image in SketchUp

By Aidan Chopra

Perhaps there’s something in a photograph you’re using, and you don’t want it to be there. You can use Edit Texture Image to open the texture you’ve selected in an image-editing program, where you can edit the texture directly.

Follow these steps to use Edit Texture Image:

  1. Right-click the texture in your model you want to edit and choose Texture→Edit Texture Image.

  2. In the program that opens, make whatever changes you need to make.

    Be sure not to change the proportions of the image — that can really mess things up.

  3. Save (don’t Save As and change the filename) the image you’re editing and close it if you like.

  4. Back in SketchUp, check to make sure your edits have been applied.

Which image-editing program actually opens depends on what you have installed on your computer; you specify which one to use in the Applications panel of the Preferences dialog box. For what it’s worth, most designers use Adobe Photoshop, but you can use whatever you have.

Take a look at the figure. In it, Edit Texture Image is used to remove a pesky element from a photograph being used as a photo texture.

Need to radically reduce the size of your SketchUp model file? Right-click any textured face in your model and choose Make Unique Texture to create a copy of the texture you’ve selected and crop (trim away everything that isn’t visible) that copy according to the face it’s on.

Why is this important? Just because you can’t see part of an image doesn’t mean it’s not there; SketchUp saves the whole photo with the model, even if you use only a little bit of it. In a complex model with dozens of photo textures, all that invisible, extra photo data adds up. Making your textures unique can make your models much, much smaller.
