Please have a look at the enclosed pic, which is a bumpmapped stone texture, from a castle wall that I am working with. However, as you will notice, there is something wrong about this stone, it looks like veins or something that sticks out of the stone.
They are actually cracks and small holes IN the stone, so they should not be hit by the light as is the case on the picture. Do you get me?
Turning the enclosed picture up side down(180 degrees) does not give a convincing result either in the 3d scene(even though it does in Photoshop)
What settings should I change in order to achieve this effect?
The pics below show:
- a screen shot of the castle wall as it appears in my 3d scene
- the shot turned 180 degrees in photoshop. I want the 3d scene to look like this, but I am not able to achieve it, even if I change the original texture photo in blender to the one below
