So I saw this pic of clouds in game The Witness and I really liked how they made the clouds. How to reproduce them?

example reference clouds

    $\begingroup$ Those were painted, probably a texture on some planes $\endgroup$ – VRM Jun 22 '15 at 20:38
  • $\begingroup$ oh..well that's a shame $\endgroup$ – Samurai Fox Jun 22 '15 at 20:50
  • $\begingroup$ ^^ the novice is right... If you download a cloud texture, set it's type to "Billboard" and make it shadeless, gigantic, and always slowly wheeling across the sky, you should be good. $\endgroup$ – Scalia Jun 22 '15 at 20:51

sorry for the previous short and unexplained answer :)

First open up blender and add a plane, then UV unwrap it like below (I've made a very simple cloud texture for that with transparency)

enter image description here

then add a plane so we can actually see something in the test render

enter image description here

then go to rendered shading mode by enabling it from the red icon indicator

enter image description here

notice how the transparency (alpha channel) has been filled with black?

its because of the default material setup as shown in the picture below! the diffuse shader can't render transparency

enter image description here

its only using a diffuse shader with a image with transparency

now, if we add a transparent shader with mix shader node and the alpha from original image as the fac value then we will get something like below

enter image description here

its basically checking weather a part of the texture is transparent and if so it is feeding it through the transparent shader so we can get the actual transparency..... and the rest is going through the diffuse shader

by this method you can get the cloud you were referring to.....

now, you might wanna import image as a plane (check if the addon is enabled) then apply this method, but for some wired reason (I don't know why) its not working in my blender 2.74... hope somebody can lighten me up :)

    $\begingroup$ This is visible form one side only? Because in the Witness the cloud is 3d...meaning that every side looks different and like a real cloud, random. $\endgroup$ – Samurai Fox Jun 23 '15 at 21:25
  • $\begingroup$ @SamuraiFox , yes one side only.... if want to get something more like real clouds then I suggest making a sphere more like a cloud (maybe with sculpting mode?) and then use Volume Scatter as the material and set the color to white... maybe add a texture to randomize it :) $\endgroup$ – jamius19 Jun 24 '15 at 4:58
  • $\begingroup$ that sounds promising...I'll try that $\endgroup$ – Samurai Fox Jun 24 '15 at 10:48
