Since a candle's flame goes from orange to yellow to blue to black (transparent), that's our goal. Next, we want to build a gradient for the fire color. Under the Fire rollout set the Intensity spinner to 1.25 and Opacity to 1. Under Temperature rollout set Temperature Buoyancy to 2. Under the Smoke rollout set Smoke Buoyancy to 0. Under the Fuel rollout, set the Ignition Temperature to 100, Burn Rate to 50 and the Burn Rate Variation to 0. Under the Simulation - > General rollout make sure that Quality is set to 5, Maximum Iterations is set to 1 00 and the Time Scale is set to 1. Now let's move on and scroll down to the Simulation rollout. You can create a new sub - folder for this one called FFXTut01. Something on the order of creating a main folder FumeFXSimData, and then creating new sub - folders for your different sims. Click on the ellipsis (.) button next to the path and then create and set a new folder location on your hard disk to store the dataĪ good option would be to put your simulation data into individual folders. Under the Output rollout you need to set a Default P ath to store the simulation data. Make sure that the Adaptive checkbox is active as adaptive grid simulates much faster than the non - adaptive one. This parameter allows you to control the amount of detail in the simulation. Go back to FumeFX node and under General Parameters set the Spacing to 0. Those are actually default values for the Object Source. Select Object Source and make sure the Fuel value is set to 1 0 0 and the Temperature value is set to 300. This method would have created new Object Source, add Object Source to selected FumeFX and also add selected geometry to the newly create Object Source.
The fastest way to perform node creations and additions is to select the wick geometry and fumeFXShape1 node and then create Object Source by clicking on the Object Source menu option (or Create Object Source icon from the FumeFX shelf). This will "tell" FumeFX to use ffxObjectSource1 for the simulation. Inside the Attribute Editor click on the FumeFX Relationship Manager button and selecte the ffxO bjectSource1. Since the FumeFX Object Source simply informs the FumeFX simulation engine of an object you want as part of the simulation, its icon doesn't need to reside within the FumeFX Grid volume.
This will create Object Source node with the wick object added automatically. Other way to connect geomery to Object Source is to select wick object in the scene and then create Object Source from the FumeFX menu. To add geometry, you'll need to select wick object in the viewport and then hold key and select ff objectSource Proxy 1 and in Object Source's attribute editor click " Attach selected". You will notice that inside the attribute editor there is no geometry selected (as seen on the image below). There are three ways to "tell" Object Source which geometry to use.Ĭreate Object Source from the FumeFX menu without anything selected in the scene. It can use any geometry in the scene as the source. Now that you have a FumeFX Grid in place, you need to create a Source to help drive the simulation.įor this purpose we will need an Object Source.
This will affect your simulation times in a big way. NOTE: Make the FumeFX grid only as large as the simulation area you need. Then in any viewport, move the FumeFX Grid gizmo into position at the top of the candle geometry. Set FumeFX size to Width=14, Length=13, Height=35. We're going to add the flame to the wick.Īfter the file loads, go to the FumeFX menu and select FumeFX Node from the dropdown list. This scene is nothing more than simple candle geometry. In Maya, select File - >Open Scene, and from your /FumeFX/Tutorials folder, select the file Tut_01_start.m a. It will also introduce you to the FumeFX UI.
