Adding Colour to Volume Noise in Maya

Suppose, for whatever reason, you want colourised noise in Maya; there are some 3d shaders that are colour based, like Crater, or Mountain, but if you want a colour version of Volume noise for example, there’s no support for that out the box, so in order to...

Using Velocity in MASH

MASH measures the velocity of all the points travelling in a network. To see the speed of your objects you can add a Points node and set the mode to Velocity, you will then see each point’s velocity printed in the viewport:   So how about a practical use...

The Papers Behind The World Node

The World Node has three distinct types of distribution. Clusters – where points are placed in clusters around other points. Map based – where points are distributed according to a density in a map. Terrestrial ecosystems – where an ecosystem is...

Setting MASH Point positions with JSON

A while ago I was asked by how you can set MASH points using JSON – a fairly specific request, but it’s pretty easy because the MASH Placer node uses a JSON dictionary to store it’s painted points, so we can tap into that to set the positions (and...

MASH & Python & meshes – Part 2: Colour Sets

Following on from part 1, in this example we take things a small step further. Instead of just sampling the mesh for the closest normal to the MASH point, we sample the mesh for the closest point and normal, this call has the added benefit of also returning the...
