Materials issue

Hi, I am new to Blender, I am using Blender 4.2 and Blenderkit.
I clicked and dragged a Brick material onto my model, but it only shows up as a colour brown colour. I can not see the bricks. I tried fixing by scaling in UV Mapping, but I cant seem to fix it. Can anyone help?
I set my scene to mm, could this be the problem?
As a new user I am not able to upload the file unfortunately, and only one image so I had to screen shot 2 images into one.

There seems to be no information that can be confirmed in the image.
If you are not familiar with blender and have a problem with how to use materials, please refer to the video below. :slightly_smiling_face:

Thanks, i just dont understanding why my model looks odd in the right in UV mapping view.
