The Brown Teapot - A part of Honki's helpful thread of uselessness.

[Honki]

Hi.

I'm going to teach you how to make a teapot look like a grogan.

First things first, you build up a studio type setup.

Don't have one, or don't know how to do one?
Then follow me.

[Honki]

STEP 1! - Material.

For this tutorial, you will require VRay Displacement. If you don't have it, you can use regular displacement, but the effect may not be as desired. No harm in trying though.

Here is a tree view of the procedural material we are going to create.

[Honki]

Place a teapot in your scene with 16 segments.
Add a VRay displacement modifier to it.

[Honki]

In the 'texmap' slot of the VRay displacement modifier, add a new 'smoke' map.

This smoke map will play the major role in our material, so it's important we get this one right if nothing else.

Once you have created it, open your material editor and drag it across to a blank slot (instance) so we can edit it.

You should change the settings to look like the image below.

Also, edit your displacement modifier by putting the amount to 4, and Shift to 1.
Make the edge length 2 pixels.

This will make the displacement nice and crisp.

You could even increase the max subdivisions, but the edge length is enough just for test renders.

[Honki]

Lets give it a test render.

Now you can see that the displacement didn't really turn out how we wanted, so we will tweak the settings and add some more depth to the map.

[Honki]

We'll begin by dropping the displacement amount and shift.
I set mine to 2 & 0.5 respectively.

Hit F9.

[Honki]

In the WHITE slot of our smoke map, we'll add a new STUCCO procedural.

Make it look like the picture.

[Honki]

Now, in the Black slot (colour 1) we will add a new SMOKE Map.

Again, Make it look like the picture.

[Honki]

In the gray slot (colour 2)
Add another STUCCO map.

Again, the picture.

[Honki]

And in the Black slot (colour 1) of the smoke map, we will add another smoke map.

[Honki]

Now in the latest smoke map (colour 2), add a new stucco map.

Confused yet? I should have named the maps.
A bit of pre-planning prior to writing this tutorial probably wouldn't have gone astray.

Just look at the damn picture.

[Honki]

and finally in the white slot (colour 2) of the Stucco map, add a CELLULAR map.

[Honki]

now when I render, I get a result like this....
It's not really what we're after.

This is mostly due to the scale comparison between out scene and our map.

(I did mention this tutorial requires extensive test rendering didn't I?)

Here's what we got originally...

[Honki]

After we make some of the map SIZES smaller, especially the first smoke map and adjust our displacement amount a bit....
