Brick Texture On Extruded Cylinder Shows All Mortar Color Very new to Blender, so I'm not sure what to research for on this problem...
If I add a mesh/cylinder I can add brick texture, then get the texture to &quot;wrap&quot; (?) around the structure just fine, as in the bottom portion of this image

If I try to resize the cylider by extruding, the entire new surface reverts to the &quot;mortar&quot; color, as in the top portion of the above image.
The same thing happens if I add a circle and extrude that.
I have tried playing with every visible parameter for the Brick Texture node, but can't get the brick texture on an extruded section.
I'm trying to use extrudes so that I can utilize snap capabilities.
Any suggestions appreciated, including helping me understand where to look for myself
Thanks in advance
It's an UV map problem
You may have correctly unwrapped the cylinder (or used the default cylinder which comes already unwrapped) but unless you are using the brand new (2.90) 3D View Transform option, called Correct Face Attributes, which allows the transform tools to edit the UV’s and vertex colors of your mesh while you manipulate the model, you'll have to unwrap the new faces too.
The UV island for the interested faces is probably collapsed onto a single line in the UV editor, which falls in corrispondence if a mortar.
