FINAL IMAGE 600

tutorial you will learn how to create a fire animation inside Maya, and adjust the settings for your own projects. We will create the fire from scratch using Maya Dynamics and Fluids. The fire animation we will create can be rendered using both Maya software and Mental Ray.

Step 1Edit

Open the scene you are going to use. I created a scene with a lighter, some lights and a white background. Step 1

Step 2Edit

Make sure the “Dynamics” menu is active, and then go to “Fluid Effects > Create 3D Container with Emitter”. Position and scale the container to match your scene.

Step 3Edit

Select the container you just created, and then go to its attributes (make sure you are looking at the “fluidShape2” attributes).

Step 4Edit

You are going to leave the resolution at a very low number for now. Change the following options under “Container Properties”. Resolution = 10, 10, 10 Boundary Y = -Y side Contents Method Temperature = Dynamic Grid Fuel = Dynamic Grid

Step 5Edit

Select only the emitter and move it down with the move tool.

Step 6Edit

Increase the number of frames. Do a playback to see how the animation of the flame is looking.

Step 7Edit

Select the container, and under the “fluidEmitter1” attributes, change the following options: Fluid Attributes: Heat/Voxel/Sec = 2.000; Fuel/Voxel/Sec = 4.000 Fluid Emission Turbulence: Turbulence = 1.150

Step 8Edit

Go to the “fluidShape2” attributes and change the following options: Density: Buoyancy = 9.000; Dissipation = 0.182

Step 9Edit

Inside the “fluidShape2” attributes, change the following options under the “Contents Details” section: Velocity: Swirl = 10.000 Turbulence: Strength = 0.010 Temperature: Temperature Scale = 1.930; Buoyancy = 9.000

Step 10Edit

If you do a playback of the fire you should see the fire reaching the top of the container and creating an undesirable effect. To fix this, you need to increase the size of the container.

Step 11Edit

Go to “Fluid Effects > Extend Fluid” open the settings of that tool, and then change the “Extend Y by:” to ’2′ and click on “Apply and Close”.

Step 12Edit

Now the fire has more space to move.

Step 13Edit

Select the container, and under the “fluidShape2” attributes, change the following options: Fuel: Fuel Scale = 1.960; Reaction Speed = 0.970

Step 14Edit

Scroll down to the “Shading” section and change the following options: Shading: Transparency = White Grey; Dropoff Shape = Sphere; Edge Dropoff = 0.440 Color: Selected color = Black

Step 15Edit

Scroll down to the “Incandescence” section, and change the graph as shown on the image.

Step 16Edit

Go to the Opacity graph and change it as shown in the image. Then modify the following options: Incandescence: Incandescence Input = Temperature; Input Bias = 0.387 Opacity: Interpolation = Spline; Opacity Input = Density; Input Bias = 0.315

Step 17Edit

If you do a playback of the fire, you should see a nice looking animation.

Step 18Edit

If you render the scene, you should see that the fire looks good now too.

Step 19Edit

If you want to modify the “Brightness” intensity of the fire, go to the “fluidShape2” attributes, and under the “Incandescence” section, change the “Input Bias” to a value that works for you.

Step 20Edit

I used Mental Ray to render the fire, but you can change it to Maya by going to the “Render Settings” menu, and at the top of the window, change “Render Using” to Maya Software.

Step 21Edit

If you render the scene it should still looks pretty great, but all of the objects in my scene disappeared (except for the fire) because they all have mental ray materials.

Step 22Edit

Lastly, if you go to the “Attributes” of the container, you can use one of the other cool presets that Maya has built in.

Step 23Edit

The image below was created using the “thickcloudPuff” preset.
