So I'm trying to learn, but I have a really hard time understanding the relation between materials, textures, UV maps and so on. So right now I have the following problem: I'm trying to make a simple red texture be a bit grainy using a noise texture. The node setup can be seen in the screenshots below. It works fine if I view it in rendered mode (I'm using the cycles engine) or export a screenshot, but the object appears completely black in material mode:
So this is probably a very stupid question, but do you mind telling me how I can fix this?
