1. Creating Fluid Dynamics Container
Create a cylinder in the
perspective view port.
Press F11 key to
jump in the face selection mode. Select all faces of the cylinder except the
top faces and delete them.
Rename the object as Emitter
and go to Edit > Delete > History to delete history.
Jump in Dynamics
mode. Go to Fluid Effects > Create 3D Container and draw a 3D fluid
container in the view port as shown in the following image.
Go to fluidShape1 attribute and set the value of Base Resolution to 50. You can change this value to 150 just before rendering for the final output.
values of Temperature and Fuel to Dynamic Grid.
Select the container
followed by the emitter object and then go to Fluid Effects > Add / Edit
Contents > Emit from Object.
Press the Play
button and you will see smoke emission from the emitter object as shown in the
Go to fluidShape1 attribute
and under Display rollout, set the Boundary Draw option to Bounding
Go to Container
Properties and set the options of Boundary X to None, Boundary
Y to –Y Side and Boundary Z to None. Set the values of
the grid as shown in the following image.
Go to Auto Resize
to turn on Auto Resize option and turn off Resize Closed Boundaries
and Resize in Substeps options. Set the values of Auto Resize
Threshold to 0.002 and Auto Resize Margin to 4.
Go to Dynamic
Simulation roll out and set the values of Damp to 0.025, High
Detail Solve to All Grids, Solver Quality to 50 and Simulation
Rate Scale to 1.300.
Go to fluidShape1
> Content Details > Density and set the values of Buoyancy to 10
and Dissipation to 0.4. Go to Velocity and set the values
of Swirl to 25 and Noise to 0.250.
Go to Temperature
and set the values of Buoyancy to 8.5, Dissipation to 0.1,
Diffusion to 2 and Turbulence to 6.
Go to Fuel and
set the values of Fuel Scale to 2.5, Ignition Temperature
to 0.1, Maximum Temperature to 1 and Heat Released
Go to Shading >
Color and click on Selected Color option. Set the color to bit dark.
It changes the color of the smoke in the view port.
Set the Incandescence
color as shown in the following image.
Set the Input Bias value to 0.7. Play with this value to control the fire and smoke ratio.
Go to Opacity and click
on the Graph button. Add the opacity values in the graph as shown in the
following image. Set the value of Input Bias to 0.300.
Go to Shading Quality and set the value of Render Interpolator to Smooth.
Go to Lighting
roll out and turn on Self Shadow option and change the value of Shadow
Quality of 1. Set the Ambient Brightness value to 0.2.
Go to Dynamic
Simulation > Temperature roll out and set the value of Temperature
Scale to 5. You will notice the sub-surface-scattering effect in the
smoke as shown in the following image.
2. Adding Lights and Wind
Create a directional
light in the scene. Turn on Use Ray Trace Shadow option.
With the fluid container
selected, go to Fields > Air and draw an icon of air field in the
With the air field
selected, go to Channel Box / Layer Editor and set the Direction X
to -1 and Magnitude to 100.
Hit the Render
button and you will see the rendered frame as shown in the following image.
3. Render Settings
Open Render Settings
window. Change the rendering engine to Mental Ray.
Open Anti- aliasing Quality roll out and change the Quality to Production quality.
Hit the Render
button to render the frames. You will see the rendered frames as shown in the
