It's outputs (color and float) can provide values for down-stream nodes such as Since the new node is of "type" multiple rather than shadingmodel Receive "noise" values from a variety of different nodes such as brownian,
Noise function was "hard wired", the new node can Unlike the node derived from the surface shader (listing 1) in which the

The "top" and "lower" color parameters will also require manual adjustment When used in a shading network the Flame node must have its "noisiness" parameterĬonnected to one of Slim's noise related nodes, such as, Template generated by Cutter is known as a "multiple" because it has more The Slim template generated by Cutter can be viewed here. Popup menu select "Export as Slim Node" - figure 2. Note thatįlame.h and flame_test.sl must be in same directory.įigure 1 shows the "flame" effect applied to a polygon. ResultF = 1 - smoothstep(t - blur, t + blur, noisiness) Īn example of a simple shader that uses the function is given next. Trivial RSL function called "Flame" implemented in a. To demonstrate Cutter's ability to generate a custom node (template) from a (custom node) directly from a RSL function.
This tutorial demonstrates how Cutter can be used to generate a template script Of RSL that becomes part of a shader that is compiled "on-the-fly" by Slim.Īrtists can take advantage of Cutter's Slim-related functionality to createĬustom nodes either in a manual or semi-automatic fashion.
