In 3DSMAX if you want to remove the texture you applied and have everything go back to the default color or settings, just click on the hammer icon (Utilities) on the right side of your screen, in the menu, then press “more” and look for “UVW Remove” in the list. Select an object and either press the remove “Materials” button or “UVW” button. That all.
Utilities > More… > UVW Remove > select object then push “Materials”
