Separating Smoke and Fire Render Passes from Fluid Simulations in Maya

Manuel Perez Sanz demonstrates how to separate smoke and fire from a burning fire fluid simulation in Autodesk Maya, creating simple render layers to obtain two separate and distinct layers for compositing.

in this tutorial I’ve used the Blackbody radiation tool for Maya

Using the Blackbody radiation tool for Maya, Manuel notes that he changed the input Bias (-1) and the incandescence Input ( X Gradient ) in the incandescence tab for the smoke layer, as the Blackbody script doesn’t allow for color change in the gradient ramp.

The blackBody Radiation tool creates a ramp based on gathered temperature values of the simulation, allowing you to input minimum and maximum temperature parameters.
