*@Huân Lê-Vương* You're right, I could have used generated coordinates as well. The reason I didn't is mainly that for a plane the Z-component is irrelevant and with generated coordinates gives redundant and sometimes problematic information. Also for the orientation of an actual pattern like this it is usually nice to be able to manually define its proportions. For example, if the room was not a perfect square, generated coordinates would result in stretching, while the UVs can easily be adjusted.

*@Simon Thommes* thanks! that makes sense

(i think i know how now)

*@victor p* Yes, that's correct. If you just used the file from this video though, it should just work.

*@Simon Thommes* Thank you

@Simon Thommes I'm still trying to figure out why each local view displays differently. I see that they are all separate objects, parented to the main suzanne, and that each child has a different material. I can't actually change the material in my shader editor for some reason to see what's going on. Why does local view affect the material display? ... ohhh... cause they're in the same location. Heh. So then why can't I select a different mat in the shader? Everytthing is greyed out.

Edit: Got it. For some reason I couldn't pick a different mat in the shader editor in Layout workspace. Switching to Shading workspace fixed it. Seems like a bug? Anyway, now I see what I'm looking at—separate channels. I couldn't read the material setup in the Material Properties as well as reading the nodes.

Edit again: I discovered it's the Pinned feature that prevents changing a material. Learning a lot about shading/editor already!

@Tighe Racicot Yep, you figured it all out! :D Sorry that I didn't explain this in the video, but I wanted to focus on the subject matter itself and use the file only as a tool for showcasing.

@Simon Thommes No problem. Totally understand. I like to really experiment, question, and break my (limited) understanding of things, so I had to dig a little deeper.

*@Abhirama Gopala Dasa* The mesh and pbject are separate things. Basically the object is what you can edit in object mode with location, rotation and scale. And the mesh is what you edit in edit mode with all the individual vertices.

Generated coordinates stretch along the mesh, no matter what the object scale is. And object coordinates are linked to the object transformation, no matter what the contained mesh is. I hope this helps.

@Min Li This question is related to chapter 1-1 where I talk about the difference of vectors and colors. I short, Blender nodes don't make an intrinsic distinction between colors and vectors as objects. The difference is only important once they are being interpreted. In that sense, yes, the difference is their range. But the sockets and nodes can usually be used interchangeably between colors and vectors.
