I am continuing to follow the shading the Scifi helmet course but am seeing some very strange artifacts when applying my textures to the object.
Here is a screenshot:
I am using the node wrangler to display my ambient occlusion texture, but it is displayign very weirdly - the underlying mesh is showing in the texture. For reference, the corresponding part of my image texture is shown in the bottom-right of the screenshot - clearly there are no artifacts. The artifacts show up when in rendered mode as well, and also show for the 'cavity' and 'color' image textures. Interestingly, some objects which use the same image file do not show these artifacts.
Any help is greatly appreciated. I can also supply the .blend if requested.
