Long story short, I've modeled Toothless from How To Train Your Dragon in Blender, and I'm now trying to replicate the effect that the runes/scales it has. I've been using blender for +2 years now but it's always been the modelling side of things and I want to branch out to textures.

I'd like to use the cycles render engine to achieve the following effect:

Toothless rune effect

Note that the stones/scales/runes are raised from the surface in a way bump/normal mapping could not achieve, and that they're more reflective and glossier.

But having never done any texture work, I've no idea of a good way of going about it. I've tried various methods, each of which did nothing like what I wanted.

Currently, the model is just that, with no runes or anything physically on it. My original plan had been to make three textures; 1) for the visual, 2) for the displacement - which would then be baked on - and 3) which would define the areas to be more reflective etc... but now I've actually tried doing it, it seems to be a tad more complex than that (as with most things blender, hehehe). I've tried a google search, but nothing relevant comes up.

I'm not asking for someone to outright do this for me because I want to learn it for myself, but any help would be greatly appreciated, be it a guise, a link to a relevent tutorial, or even just a helpful hint.

Thanks so much to anybody who can help me out here!

(As a footnote, I've already done the model and manage to get the materials sorted for the eyes and surrounding area. Once it's finished, I'm putting it in the public domain for anyone to use, and I'll happily say you helped ;) )

The following is a way to handle displacement in a way that offers a lot of control and works very well for baking various types of maps including normals, height and ambient occlusion.

To start with, add a multi-res modifier to your model as shown in the following image. enter image description here

Now make sure you are back in Object mode and increase the number of subdivisions for the modifier.

enter image description here

Now that the mesh is ready for geometry displacement you can add a Displace modifier as shown here. enter image description here

Now once you've added displacement it could look something like the following

(For people that don't know this already, if you right-click on an image here on StackExchange, then choose 'View Image' you will be able to see the larger version so detail is more clear.)

enter image description here

For the nodes, I've used the same basic setup as username:GiantCowFilms with a brightness/contrast node added in to adjust the mix between Shiny and Diffuse.

The same image is being used for the Material and the Displace Modifier.

  • $\begingroup$ This is more like what I was looking for! This allows me to set the features as physical things, AND make them more reflective. Thanks especially for the images as well, they really really helped! $\endgroup$ – TheModerator Jun 23 '14 at 19:40

Here is how you can create you desired effect: nodes The set up uses two textures, one for the displacement and the other to control reflectivity. Notes

  1. You can use an image texture instead of the noise texture.

  2. You can add a color ramp between the texture and the mix shader node to add more control to the effect.

Edit:

Here is how you can add a uv map to the texture:

enter image description here Make sure that you get the name of the uv map perfect, otherwise it will not work.

  • $\begingroup$ Excellent! I'll give this a try ASAP. I take it when I select Image Texture it will let me specify the UV map to use? $\endgroup$ – TheModerator Jun 21 '14 at 19:52
  • $\begingroup$ Yes, see the edit $\endgroup$ – GiantCowFilms Jun 21 '14 at 21:41
  • $\begingroup$ user2926289, there is now a UVmap node available for the latest builds. This node does not give us grief about spelling since it has a selection of all available UV's. $\endgroup$ – MarcClintDion Jun 22 '14 at 10:57
  • $\begingroup$ Good to know. I don't use test build features in answers(unless that is very relevant to the question) to eliminate confusion. $\endgroup$ – GiantCowFilms Jun 22 '14 at 14:55
