 The rendering of block in Dynmap is accomplished via a number of distinctive mechanisms, reflecting the needs of the different types of blocks defined by Minecraft and by its mods.  In all cases, the rendering of a block consists of two core elements: a **model** defining the shape of the block to be rendered, and a set of **textures** used to apply color to the various surfaces of that shape.  Thanks to the very 'blocky' nature of Minecraft, the majority of blocks are shaped like simple cubes: consequently, most blocks do not need a custom **model**, and can instead be assumed to be a simple solid cube.
 
-Support files for custom blocks defined by add-on mods are provided through the definition of two files for each mod: one defining the texture mapping (following the naming convention '*-texture.txt', and placed in the 'renderdata' directory (or in a subdirectory under that directory)), and a second defining the models for blocks that are not simple cubes (following the naming convention '*-models.txt', and also placed in the 'renderdata' directory, or a subdirectory).  For mods that have nothing but simple cubes, no *-models.txt file is required (as the model for any block without a model defined is assumed to be a simple cube).
