I am new to blender and I am trying to add a clay like material to an object in blender.
I tried using a material but I want the object to have a rough imperfect dull surface like play-doh. Is it even possible to do that?

    $\begingroup$ By the way, clay materials and "play-doh" materials are different. $\endgroup$ – wchargin Nov 17 '13 at 16:24

For a clay material, simply set the Specularity to 0:

If you want it to be more like "play-doh" you might want to raise the specular lighting by a bit (maybe to 0.1), but it will also be important to actually deform the model some. Play-doh shapes aren't perfectly smooth. I find that using a Voronoi texture on a Displace modifier, followed by a Cast to Sphere, works pretty well. Here's an exaggerated image and a more realistic image:

Finally, here's the modifiers and texture setup I used:

  • $\begingroup$ this works but it tends to deform my objects i already made $\endgroup$ – user2883800 Nov 17 '13 at 19:37
  • $\begingroup$ @user2883800 Yes. That's the point. That's why I said that it's "important to actually deform the model some." Sometimes appearances are about more than just materials. If you don't want to deform at all just don't include Cast or Displace; if you want a different method, try a bump map. $\endgroup$ – wchargin Nov 17 '13 at 22:25
  • $\begingroup$ I found another way to create a clay surface and it is working well. Thank you for your help though. $\endgroup$ – user2883800 Nov 18 '13 at 2:59
