 This doesn't do anything at the moment. Eventually it will replace the *Random Seed* with a new random number. This doesn't do anything at the moment. Eventually it will replace the *Random Seed* with a new random number.
 +=== 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.

 This is the maximum transparency value if **Randomize** is enabled. The random transparency will be in the range from **Base** to this value. This is the maximum transparency value if **Randomize** is enabled. The random transparency will be in the range from **Base** to this value.

 +===== 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.
