How do I edit PBR textures

Hello, I am currently attempting to place a PBR file onto my design. Whilst I have succeeded in applying the texture, for some reason I cannot edit the texture under texture mapping. I am adjusting scale and no matter what I change it to, it is all the same. Any and all advice would go a long way. Thanks in advance to any and all help.

if you look below your arror there is a further field, there use repeat. you can also switch the type from surface to planar which is a bit further above, then you can change the values you have pointed out.

Are you in an older Rhino? (not Rhino 8). Posting the file will help us solve the issue. Based on what I can see, the values you’re trying to adjust will likely only be able to be adjusted from within the material itself. If you apply mapping to individual objects there’s a few things you’ll need to do.

In Properties > Texture Mapping, you’d need to edit the Repeat in the UVW section at the bottom since the mapping method for the object is set to Surface type. Alternately, you could edit the texture within the material or scale the UV islands in the UVeditor for the object.
