I'm working on a bathroom interior, and I figured that one of the main things I need is to have a good drywall bump map. I've looked around online to see if there are any good drywall type bumpmaps, but I haven't found anything good/free to use. Is there anyway that I can create a convincing bump map that looks something like this image (in Cycles):

enter image description here

(Ignore the towel holder). It's okay if it's tile-able, but it needs to be big enough so that it doesn't look repeated. If a similar effect can be achieved through procedural textures, I'm all for it.

    $\begingroup$ I think GIMP has something like that $\endgroup$

  • $\begingroup$ @NoviceInDisguise Okay, I have GIMP. $\endgroup$ Jun 6 '15 at 22:50
  • $\begingroup$ Get a good image texture, and go to Filters > Map > Bump Map. Make Seamless is in the same place as well if you want that $\endgroup$

  • $\begingroup$ @NoviceInDisguise Okay. By "Get a good image texture", do you mean take a picture of my wall? $\endgroup$ Jun 6 '15 at 22:56

    $\begingroup$ Sure! An image of the type of wall you want to replicate $\endgroup$

I'm going to assume here that you have a high resolution image of the wall you want to replicate. I'm going to be using this texture from cgtextures.com.

The best way that I know of for this, is to import it into gimp, crop it to a 1:1 aspect ratio: enter image description here

You then use the make seamless filter to get this result: enter image description here

Then import it into Blender and use the bump node to generate a normal map. enter image description here

Please note that this is how I like to setup a material, but the only important parts are the image texture and the bump nodes.

  • $\begingroup$ Okay, my problem is finding a high resolution image. Thanks for the help! I'm thinking I might just go semi realistic and use a procedural texture... $\endgroup$ Jun 6 '15 at 23:04
  • $\begingroup$ I would recommend doing it procedurally if you can, not tiling then $\endgroup$

    $\begingroup$ Okay, just updated with images. $\endgroup$ Jun 6 '15 at 23:28
  • $\begingroup$ @NoviceInDisguise Okay. Can you think of any good procedural setups? Thanks! $\endgroup$ Jun 6 '15 at 23:30
  • $\begingroup$ A procedural texture is definitely a good idea if you can get it to work. If you haven't already, check out Bartek Scrupa's Blender Conference video on working with texture coordinates. youtube.com/watch?v=kAUmLcXhUj0 $\endgroup$ Jun 6 '15 at 23:30
