I want to recreate those glass-bricks. For the deformation I thought to use different noise/musgrave texture as displacements.

enter image description here

The bricks are deformed in different sizes:

  1. The whole bricks are deformed/curved - one is standing more out than the other - for that I use a really big noise

    enter image description here

  2. the surface is not completely flat so I want to use a smaller noise to add the little bumps

    enter image description here

  3. and finally there are fine lines for which will use another noise texture

How can I stack one displacement on top of another? First I want to have the big displacement, then when the brick is deformed the next displacement starts to displace the surface again and so on.

Is this possible?

You can combine multiple color sources using the Mix node :

  1. Big noise : enter image description here
  2. Small noise : enter image description here
  3. Mix node : enter image description here

The great benefit of the Mix node is that you can adjust the blending of the levels of details. Here I've set the Fac to a very low value, so that the little details are barely visible.

  • $\begingroup$ the problem i have with this method is, that it creates a mixture of the texture and not a chronoligical adition. Areas that are already 100% black or white cant be affected by the same color from the following texture again.. becaus its already at 100%. What i want is that blender calculates the first displacement, shape 1, then adds another displacement on shape 1 to get shape 2. what blender does now it takes displacement 1 and 2, creates a median of those two: shape 1. or am i undestanding blender in this case wrong? $\endgroup$
