i have a whole pile of cubes, with a texture repeated on them. i want the smaller cubes to have a different repeat rate on them, so i select these cubes, and press P to separate them. new objects, same material.
i go material, add new. new objects, new material SAME TEXTURE
next, i select the repeated texture, and go texture, add new, thus creating a new texture. i change the repeat rate, and if i go between the two types of cubes, i can see the repeat rate changes, so voila, new object, new material, new texture.
now, to help myself i changed the colour of these cubes, just their base colour so i can see which cube has what material, and i noticed that it did not update its colour in the 3d window, which was rather odd.
same thing happens when rendering, even if i turn off the texture alltogether, it still renders with it on.
