Nodes are the essential building blocks in the Advanced interface to the Poser Material Room. They are the graphical representation of mathematical function calls, that is: calculation procedures which turn parameters (inputs) to a result (output).<\/p>\n

\"\"Advanced<\/strong><\/p>\n

The various nodes from the 2D Textures group all serve the same purpose: offering an image or tiling pattern which is to be (UV-) mapped onto the object surface. Image_Map <\/a>and Movie <\/a>do so with external static or dynamic sources. The other options generate patterns on their own. Let\u2019s have a closer look at those.<\/p>\n

In all cases: for each portion of an object that has its own UV coordinates, both U and V vary from 0.0 to 1.0. U mainly in horizontal direction, V in vertical direction.<\/p>\n

Wave2D<\/h3>\n

This node generates a circular sine wave pattern, which is ideal for wavy displacement maps.
\n\"\"<\/p>\n

The U_pos<\/strong>, V_pos<\/strong> parameters determine the center of the pattern, Frequency<\/strong> determines the number of repetitions and by animating the Phase<\/strong>, the pattern starts rippling.
\n\"\"<\/p>\n

As a single pattern looks quite simplistic and cartoony, one can combine patterns with different frequencies (and origins, phases as well) to make more complex, realistic ones.<\/p>\n

Brick<\/h3>\n

This node generates a brick & mortar texture, in the first place for use in the Diffuse slot, or in combination with its alternatives. But because brick and mortar behave different for specularity, and for bump\/displacement, variants of the node are usually combined with some other components of the PoserSurface.<\/p>\n

\"\" \"\"
\nBrick_Width<\/strong> and Height<\/strong>, and Mortar_Width<\/strong> define the main aspects of the texture, while U_offset<\/strong>, V_offset<\/strong> define the placement of the texture on the object. Note that all of those are expected to vary within the 0..1 bound.<\/p>\n

Turbulence<\/strong> makes the mortar-lines less straight and perfect, while Noise<\/strong> makes the mortar filling more irregular. As the manual states: Turbulence is low frequency, Noise is high frequency variation. In plain English: Turbulence affects the shape of the stones, Noise affects the structure of the mortar. I can choose between original and improved noise, the first one is meant for compatibility with older Poser versions.<\/p>\n

Softness<\/strong> defines the brick-to-mortar distinction, the higher the value the more brick blends into the mortar.<\/p>\n

Tip: believable brick textures do need serious variation in brick color and brightness. Using additional (non-brick) textures for Diffuse_Value, or plugged into to Brick_Color slot, can help a lot in this. Especially the Clouds node (from the 3D Textures collection) might be a nice one.<\/p>\n

Tile<\/h3>\n

Although the Brick node can be used to make shiny tiles as well, all of those will be in a similar color, and all of them will be rectangular too. The Tile node makes a variation on this, by offering alternating colors, and roundish (ellipsoid) shapes as well.<\/p>\n

Parameters are similar to Brick: Tile_Width<\/strong> and Height<\/strong>, and Mortar_Width<\/strong> define the main aspects of the texture, while U_offset<\/strong>, V_offset<\/strong> define the placement of the texture on the object. Note that all of those are expected to vary within the 0..1 bound.<\/p>\n

Turbulence<\/strong> affects the shape of the tiles, Noise<\/strong> affects the structure of the mortar. I can choose between original and improved noise, the first one is meant for compatibility with older Poser versions. Softness<\/strong> defines the brick-to-mortar distinction, the higher the value the more brick blends into the mortar.<\/p>\n

Weave<\/h3>\n

Weaves are meant for cloth, but of course one can make nice garden fences with it too. It\u2019s just a matter of scale (and color, and material details). This:

\n\"\"<\/p>\n

The colors speak for themselves, and the U_Scale<\/strong> and V_Scale<\/strong> determine the amount of threads on the surface (times two, as the object surface apparently has U and V from -1..1). So the plane shown above has 2x 10 (U-Scale) threads in Color-1, and 2x 20 (V-Scale) threads in Color-2 which then of course have half the thickness.<\/p>\n

To my observation, the Height<\/strong> parameter has no effect at all. Larger Bias<\/strong> values create thicker and flatter threads, or: reduce the space between them. Larger Gain<\/strong> values sharpen the texture, higher values make more distinct threads, as for paper \/ wood strips while more fuzzy threads are fine for textile weaves. Bias and Gain vary from 0.0 to 1.0. Note: at other places Bias is defined as brightness of the underlying greyscales, and Gain is defined as its contrast, both as if applied by Photoshop or alike in a pre-processing stage.<\/p>\n
