Mudpot is a very simple texture with only a few parameters.  The name indicates that it basically looks like the surface of bubbling mud.

Parameters :

Position : Position of the texture.

Scale : The texture is scaled by this value.  Use these parameters to scale or stretch the texture in one or more directions.

Tension and Speed : Higher values for both of these make the surface have tighter detail in slightly different ways.

Notes : This texture looks interesting when stretched along X or Y.
