Apply an FFD 2x2x2 modifier to your stack.  Then you can deform the teapot to enhance the 'splat' effect (or, for more control, use a 3x3x3 or a 4x4x4 FFD modifier instead).  I used a 2x2x2 for this example. (Fig.19)


I know you're excited, so let's have a look! (Fig.20)

Ewww… Now we are indeed looking "pooey”…

Step 6: Colouring In!

Without further ado, let's give this little fella some colour!  In a blank material slot, change the material to 'Blend'.  Drag your special displacement map over to the mask slot.  Make sure you 'instance' it so that any changes made to your displacement map later will also be made to this slot, and vice versa. (Fig.21)



I added 2 materials with different colours to each of the material slots, so you can see how the effect will come out.  I used vray materials, but you can use any material you want in the 2 blend slots.(Fig. 22)


I used the following settings for the primary material. 

I added a vray dirt map to the diffuse slot.  This material determines the primary colour of the teapot.  There is no requirement to use a vray dirt map, so if you don't have vray then just use a flat colour or whatever alternative suits you.

I also ‘instanced' the displacement map again into the bump map slot of the material. (Fig.23, 24 & 25)
