Setting up FumeFX Simulation
Now in order to set up FumeFX, you need to create a container in which all effects are simulated.
First, we need to set up the FumeFX data and make it ready for visual presentation. Go to the standard primitive panel, hit the dropdown menu and select FumeFX.
Now you can create a container, in the same way you create a box using geometry.
After you have created your container, go to the modifier panel to open FFX_GUI and its related parameters. As a note here, you'll need to check which version of FumeFX you're using. I'm using FumeFX 3.0.1, which has no major differences with the latest version of the program, but older versions may prompt a few messages. Don't worry though, this tutorial and its files can be opened into any version of FumeFX.
Now FumeFX contains 4 main menus and 6 very important tabs. The Simulation tab is the main engine of FumeFX, so I'll focus more on this part. I'll break it down into 2 subsections: one where we'll add particles into our source and another where we'll tweak settings from FFX GUI.
Finding FumeFX in the menu panel
First, save your file as 'LargeScale_Explosion_WIP'. Now go to the helper section and hit in the dropdown menu > FumeFX > Particle Source. Select the particle flow you created earlier, and place it in the FumeFX source stack.
Finally amend these settings here:
• Radius: 12.692
• Variation: 10.0
• Velocity Multiplier: 1.65
• Variation: 10.0
• Fuel: (Add type, Amount: 100.0, Variation: 10.0)
• Temperature: (Add type, Amount: 2000.0, Variation: 10.0)
Amending the following settings
Setting up FumeFX GUI
We'll start with the settings from the FFX General tab. The General tab contains 4 sub-tabs containing general parameters, output, playblast, and 3ds Max script.
Adjust the following settings:
o General Parameters sub-tab
• Spacing: 2.5
• Width: 1500.0
• Length: 2500.0
• Height: 3000.0
• Adaptive: CHECKBOX ON
• Sensitivity: MIXED
• Threshold: 0.01
• Size: 600 x 1000 x 1200
• Simulation up to 31586, and Render up to 17583 are my values for the final result. You may choose your own desired value – but try not to lower your spacing too much.
o Output sub-tab changes.
• Start Frame: 0
• End Frame: 100
• Viewport Update: 1
• Exported Channels: Fuel, Smoke, Temperature, and Velocity.
• Make sure that you set your default path to one folder for caching out the entire simulation.
o Playback sub-tab changes.
• Play From: 0
• Play To: 100
• Start Frame: 0, while the rest remains the same.
