Changing material doesn't change wall appearance

[Anonymous]

I have been trying to change the materials on walls so I can change their appearance but those walls have default materials still even after applying the material change.

I never had such problems. If anyone could give me solutions it'll save my life

Thank you ahead!!

Looks like you painted over the wall surface with another material.  Remove it and see if you can see your wall material then. 

...if you need further troubleshooting with this Material, please post your "Black rock1.PNG".  Other than that, your walls reflect accurately the Material that is assigned to them.

I forgot that I have painted another material over...

Thank you for your help!!
