Basic Textures from NodesThe Poser Material Room allows us to create some basic textures just using built in functions. This is my list of patterns produced using just nodes, no texture maps.Gradients Basic Gradients can be created from one or two nodes, depending on the alignment you require. Our starting points are the 'U' and 'V' nodes, found in the Variables group. These get us horizontal and vertical gradients, although only in one direction.
To flip them, we use the 'math_functions' node found in the Math group. Here we have set the function to Subtract, both Value_1 and Value_2 to one, and pluged our U or V node into the Value_2 input. In effect we are subtracting our original node from a solid white background. Changes to Value_1 and Value_2 will change the brightness of our gradient. Lower Value_1 to darken the gradient, lower Value_2 to brighten it. Diagonal gradients can also be created from combinations of the functions used above. Following our screenshot here, to get a gradient from the top left corner plug the 'V' node into Value_1 of the top Subtract node. To get a gradient from the bottom right, plug the 'U' node into Value_1 and the 'V' node into Value_2. To get a gradient starting from the bottom left corner, plug the second Subtract node into the Value_1 node of the first Subtract node. Finally, to get a gradient from the top right, reverse the inputs from above - plug 'U' into the Value_1 node and the output from the second Subtract node into the Value_2 node. These gradient nodes can now be plugged into the inputs of every other node to get increasingly powerful effects - how about spots that get smaller towards the bottom of a texture? |
