# I Can't Add an Operator

If you can’t add any operators (i.e., the *+ Add operator* option isn’t available), it means the textures are already being used in a material. This is actually a safety feature of the platform, designed to reduce errors that could occur when a single texture is used by multiple materials and editing that texture would unintentionally modify all of them.

In that case, you can simply copy the existing texture as follows:

<figure><img src="/files/C6GDdmNaDWEmk3jSFTir" alt="" width="472"><figcaption></figcaption></figure>

And once you are **done** with your edits then in the material select your new revision like so:

<figure><img src="/files/8KM9VjdKqVTHC3kKW2dS" alt=""><figcaption></figcaption></figure>
