Disappeared texture in material property list

I have a problem with one of my project. In material property list texture property is disappeared.
Here is two screenshots of different projects.

What may cause such problem?

Click on the material header to show/hide the details. (From an usability standpoint, I think there should be one of those list arrows that points to the right when it’s collapsed and down when it’s uncollapsed, so this functionality is more obvious.)

Aha ha! :slight_smile:
