+ | === Noise Frequency === | ||
+ | The randomness of the placement of the images as well as their rotation, scale, etc. is based on a noise function. This setting changes the scale of that noise. | ||
+ | Larger values make it more chaotic, smaller values less so, which will lead to images next to each other using more similar settings. | ||

+ | ===== Node Connections ===== | ||
+ | ==== Inputs ==== | ||
+ | |||
+ | ==== Projection ==== | ||
+ | Connect a Projection node to define the texture projection used for the node. If it's not connected, the default UV Map will be used if has been defined. | ||
+ | |||
+ | |||
+ | The other inputs correspond to the controls with the same name. Please remember that the inputs change the values per (surface) spot that is evaluated. | ||
+ | ==== Outputs ==== | ||
+ | |||
+ | === Colour === | ||
+ | |||
+ | This is the final composite of the random images over the background colour. | ||
+ | |||
+ | === RGB === | ||
+ | |||
+ | This is just the colour of the random images. If no image is visible at a spot, it will be black. | ||
+ | |||
+ | === Luma === | ||
+ | |||
+ | This is the luminosity of the **RGB** output. | ||
+ | |||
+ | === Alpha === | ||
+ | |||
+ | The transparency of the random images, taking their respective alpha channels into account. | ||
+ | |||
+ | === Bump === | ||
+ | |||
+ | A bump map computed from the luminosity of the images. | ||
+ | |||
+ | === Tile Value === | ||
+ | |||
+ | This is a random value between black and white (0 .. 1.0) for each tile, taking the alpha channel of the mapped images into account. | ||
