I’ve got a problem which is affecting negatively the shading of my model with Cycles.
Basically, some kind of checkered pattern appears there. This pattern doesn’t seem to be the usual test one that can be set when doing UV unwrapping. Please note that I haven’t even attempted doing that, at least intentionally.
By setting the viewport shading mode to “textured” it’s apparent that portions of the 3d mesh have a different texture than others:
As you can see, the Cycles rendered view is also negatively affected:
What could be the reason of this?
How do I get rid of this texture, making the mesh surface look like the hood of this car?
