Blender 3D: Noob to Pro/Basic Carpet Texture

GoalEdit

I am using a basic scene that I quickly set up before I started to create the carpet material. It shows a monkey (suzanne), a plane, camera, 3 area lamps and 1 spot lamp.

The basic scene setup

The purpose of this tutorial, is to highlight the power of blenders built in shaders and procedural textures to create a carpet material to use in your scenes.

NOTE:  For those of you needing help getting a similar scene to the one above, here are some axis positions,etc. to help out:
(Spot-Lamp)-X=1.62,Y=0.86,Z=6.74;rotation-X=37.26,Y=3.16,Z=181.34;
(Area-Lamp-1)X=4,Y=3.27,Z=4.12;rotation-X=54.67,Y=-18.59,Z=-109.47;
(Area-Lamp-2)X=-2.07,Y=-2.08,Z=4.85;rotation-X=29.37,Y=-28.98,Z=355;
(Area-Lamp-3)X=0.315,Y=-2.89,Z=4.29;rotation-X=49.23,Y=-10.63,Z=6.68;
(Monkey)X=0.05,Y=0,Z=0.42;rotation-X=58.61,Y=-16.07,Z=23.245;DIM(dimensions)X=2.734,Y=1.969,Z=1.703;
(Plane)x=0,y=0,z=0;(no rotation);Dimensions: X&Y=14.30,z=0.

Alternatively, you could also download a pre-made file in case that you're in a hurry.

NewbyNote: With these settings, I get a big white-out.

NoobNote: Try adjusting each of the area lamps Dist(ance) value. This helped me.

NoobQuestion: How does the above coordinates help me at all? I haven't found anything that tells me were in 3D space object actually is or the objects dimensions little alone control them. Nothing in the Tutorial up to now even gives a clue to this.

NoobAnswer: Hit 'N' to bring up the Transform Properties window and enter the values there.

The Basic Material and Shader SettingsEdit

For the basic material for the carpet set the color settings of your material as follows -
Col (R 0.714) (G 0.134) (B .134) Dark Red
Spe (R 0.590) (G 0.210) (B 0.084) Reddish Brown
Mir (R 1.000) (G 1.000) (B 1.000) White

Change the specular shader to ('phong') and leave the default lambert diffuse shader as it is. Change the ('spec') to [0.13] and the ('hard') to [12]. Lastly click the ('Full Osa') button to enable it. If you render now you will notice that the plane looks like an ugly pastel color (if not, you have a different lighting setup to mine and the shader will not look the same as the images in this tutorial.) Don't worry about this ugly looking plane it will soon be a beautiful carpet.

Cloud Texture 1Edit

Press 'F6' on the keyboard to bring up the texture panel. Click the bottommost of the long boxes to create a texture in the bottom channel. Create a new texture and rename it something like 'Red Clouds 1'. From the ('Texture Type') pull down select clouds. In the 'Clouds' settings panel change ('NoiseSize') to [0.210] and ('NoiseDepth') to [4].

Now select the Colors tab which will bring up the ColorBand for the texture. Press the orange ('Add') button to add a cursor on the colourband. Next make sure the 'Cur : 0' is showing next to the add button and change the colours as follows - (R 0.770, G 0.168, 0.168). Now click on right side of the 'Cur : 0' so it shows 'Cur : 1'. Change 'Pos' to 0.6. Set Alpha to 1 and change the colour to (R 0.732 G 0.243 B 0.243).

Now go back into the material settings and change the settings in the Map To tab as follows. Click ('Spec') twice so the text becomes yellow do the same for ('Hard'). Now select 'Subtract' for the texture blending mode. Change ('Col') to [0.188].

At this stage if you render you might find it hard to notice the difference, it is apparent only where there is low light levels on the plane, don't worry about this at the moment. It means if you render with Ambiant Occlusion you get a nice carpet effect of slightly varying colour.

Cloud Texture 2Edit

Go back to the texture panel and create another texture, call it 'Clouds' and put it in the channel above 'Red Clouds'. Change ('NoiseSize') to [0.054] and ('NoiseDepth') to 4. Select 'Improved Perlin' from the Noise Basis pull down. Finally change ('Nabla') to [0.031]. Do not change any more settings here.

Now in the material panel, under the Map To tab change the following - Click ('Nor'). Click ('Spec') and ('Hard') twice so as they are yellow.

Render with the 2 textures so far

As you can see the material is starting to look a bit better, only 2 more textures to go.

The Final Cloud TextureEdit

Switch to the texture panel once again and create a new Clouds texture in the next channel up. Change ('NoiseSize') to [0.010] and ('NoiseDepth') to [6]. Now click on the 'Colors' tab and change the colour of the left cursor ('Cur : 0') to (R 0.713 G 0.262 B 0.223) and Alpha to 0. Switch to Cursor 1 ('Cur : 1') and its colour settings (R 1.000 G 0.363 B 0.000) and Alpha to 1.

Texture 3 texture panel Screenshot

Now in the materials panel under the 'Map To' tab Click ('Nor'). Click ('Spec') and ('Hard') twice so as they are yellow. Leave the blending mode as 'Mix'. Change ('Col') to [0.464] and ('Nor') to [1.00].

The Last TextureEdit

Finally, go to the textures panel one last time. Create a new Stucci texture in the next channel up. Change ('NoiseSize') to [0.006] and ('Turbulence') to [10.94]. Click on the 'Colors' tab. The first cursor 'Cur : 0' should be black with alpha 0. 'Cur : 1' should be red (R 1.000 G 0.000 B 0.000) with alpha 1.

Texture 4 textures panel

Now go to the materials panel. Under the 'Map To' tab Click ('Nor'). Click ('Spec') and ('Hard') twice. Change the Blending type to 'Subtract'. Change ('Col') to [0.056] and ('Nor') to [0.50]. And that's it. When you render now, you should have a nice-looking carpet material. By tweaking with the colours you can create any colour of carpet.
