  • $\begingroup$ do it procedurally with a Noise Texture, the one you can see on my screenshot, that is plugged into a Bump node $\endgroup$ – moonboots Dec 27 '20 at 9:38
  • $\begingroup$ Can you please show an example how to do this? $\endgroup$ – Ehtiram Memmedkerimov Dec 27 '20 at 9:41
  • $\begingroup$ what do you mean exactly? You just need to copy the exact same setup as the one I've linked, then select the faces of your object that are supposed to have this material (you need to have the correct topology of course) and click on Assign, it should work fine, you'll just need to tweak some values like Transmission $\endgroup$ – moonboots Dec 27 '20 at 9:44

Just to illustrate moonboots's comment.

  1. Use Noise texture with a Bump node.
  2. Set Bump node Distance to around 0,001 or less (1 milimeter)
  3. Done.

    $\begingroup$ Hello :). We're trying to keep it one question per post on this site. If you have another question, feel free to ask it as a new post - you can link this one to provide context. $\endgroup$ – Jachym Michal Dec 27 '20 at 11:18

If you want the "smooth" areas with a pattern like in the image, you can mask some parts of your Bump Map by multiplying it with a (rotated) checker texture. You will probably have to make a lot of transformation adjustments (size, rotation, location, etc..) before it fits your project perfectly, though:
