Hi All
I use Blender as my modeling and animation tool. I’ve created some models with material including some procedural textures that influence both roughness and color of my model.
How can I export the all model (with the material) into Unity?
I use Unity 3.3 pro and Blender 2.57b
Thank u in advance
Howdy, I’ve been working with blender and Unity and this is what I do.
1). So in Blender, be sure to assign the right materials to your objects, and as you know you can assign multiple materials to multiple objects. make sure you’ve done this.
Here is a link to help with that step:
2) After that, you’ll need to UV Unwrap in blender. Of course, a quick and dirty way is to use the “Smart” Unwrap". However, the ‘correct’ way is to use seams. You can access these menu’s in blender with Ctrl E, for seam marking/ and clearing. Since your procedural texture will tile across the model, you should make sure the unwrap looks right in the UV editor. You can easily apply a test grid texture to see how it turns out, especially over Complicated models.
Here are two links, one simple and another more advanced on this topic.
3) Now Export the Model as an FBX, and drop the FBX into your assets folder. For ever material you had assigned, Unity makes a Materials folder, and makes an empty material. What I do at this point is add another folder called textures. Here is where we assign your textures to the slots in the materials.
Unity Does this part. Assume you had a bumpy wood texture, this consists of a normal map and also a diffuse map. For the appropriate Material (correspoinding to the fbx export), simply select bumped diffuse from the dropdown menu. Now, drag the color information to the diffuse part, and the blue-bump information to the other. You shoudl see the result appear in the Unity material preview. You can even switch between cube, spehere, and cylinder to make sure it looks right. Now, how this material tiles across your model will be determined by how you UV unwrapped from before.
If you’re unclear on this part of the process, here is a video to help:

Now do this for every material!
You might have to play with the repeat setting in the Unity material editor to make it look correct. For htings like metal and glass, there are other texture types that will work. Specular, for example, will give you shiny stuff. More on that here in the Unity manual on textures.

Read a little here on the texture types, to bring it all together like you like.
Edit: so did this answer your question? Do mark it as answered if so.
I would suggest baking the procedural textures into a UV image or bump map before importing in Unity, as I believe Unity does not have the ability of emulating said procedural textures. Also unity has a different set of Materials, try using Bumped Diffuse or Bump Specular under the shader type with the textures that you baked. Baking options in blender are under the Render tab, at the very bottom.
Here’s a small tutorial about this, though it uses 2.49
For me I have to manually bring in the texture. But it automatically has the UV material mapped. I have to link the texture to the material, and then it renders.
How do you export the material that was used in blender?
