The Phase Function for the smoke is set to 0.7 so that the light can scatter more and give the lighter smoke steam appearance. The scene contains a primitive called "Blocker" which is a Solid Object until frame 74 and holds the smoke generated by the Boosters below the Launchpad, after frame 75 the Blocker is set to a Non-Solid Object and the smoke can start travel upwards. Since the scene has a lot of geometry and we wish only a few parts of it to interact with the simulation, the Scene Interaction is set to Include list and only the objects relevant to the simulation are picked. For the rendering the Smoke Scattering is set to Ray-traced in order to get more realistic scattering of the light through the smoke.
Another two Fire Sources in Volume Brush mode are used to change the RGB color of the smoke near the ground to give it more variation. A Fire Source in Volume Inject mode is used for the smoke emission from the rocket and the boosters. This scene demonstrates how to set up a rocket launch scene using Phoenix. The following samples illustrate the usage of different features in Chaos Phoenix.
