Tick Enable Alpha Channel if you wish to use an alpha for this texture.

  • Keep current alpha: Will use the existing alpha in the image file if one is present.
  • Fully opaque (white): Can be used in certain cases where you explicitly need a white alpha and none is present in your current texture file.
  • Fully transparent (black): Can be used on specular textures in case you don’t want an environment reflection on your object.
  • Set from grayscale image: in case your graphics program doesn’t let you work with alpha channels in a comfortable way, make your own greyscale image and load it in with this feature.

Click on Continue to commit your settings and return to the Image Editor.

And that’s it for working with TIFF and PNG files for your Sims 3 textures!
