Requires Phoenix FD 3.12.00 for V-Ray Next and V-Ray Next for Maya Hotfix 1 Official Release for Maya 2015+. If you notice a major difference between the results shown here and the behavior of your setup, please send an email to support@chaosgroup.comreach us using the Support Form.
The instructions on this page guide you through the different workflows available for controlling the RGB Grid Channel of the Phoenix Simulator in Maya.
The tutorial is divided in chapters covering different topics such as:
Using a Phoenix Source to emit a uniform RGB color.
Using a Phoenix Source to emit RGB from a texture.
Using a Phoenix Source to emit RGB from the vertex colors of the source geometry.
Using a Phoenix Source in Brush mode to change the RGB color of Simulations while the simulation is running.
Using a Phoenix Mapper in conjunction with a V-Ray Distance Texture to change the RGB based on the proximity of an object in the scene while the simulation is running.
All these workflows are suitable for both Fire/Smoke and Liquid simulations.
The Download button below provides you with an archive containing example scenes based on the instructions on this page.
Scale is crucial for the behavior of any simulation. The real-world size of the Simulator in units is important for the simulation dynamics. Large-scale simulations appear to move more slowly, while mid-to-small scale simulations have lots of vigorous movement. When you create your Simulator, you must check the Grid rollout where the real-world extents of the Simulator are shown. If the size of the Simulator in the scene cannot be changed, you can cheat the solver into working as if the scale is larger or smaller by changing the Scene Scale option in the Grid rollout.
Go to Windows → Settings and Preferences → Preferences → Settings and set the Working Units to centimeters.
Set the Time to 30fps. We do this to ensure the setup is identical to the Simulation RGB Workflows tutorial for 3ds Max. You may skip this step if you find it unnecessary. Keep in mind the final result of your simulation may turn out slightly different.
