Step 3

Create a cylinder shape in the perspective viewport.

Step 4

With the cylinder selected, press F11 key to jump in the face selection mode. Select and delete the lower part of the cylinder. This will act as an emitter object.

Step 5

Jump in Dynamics mode and go to Fluid Effects > Create 3D Container to create a fluid container in the viewport. Keep the emitter object inside the container.

Step 7

Press the play button and you’ll see smoke emission from the emitter inside the container.

2.Tweaking Fluid Properties

Step 1

This is quite a basic smoke without having any volume and fluid essence. You need to tweak some properties and parameters.

Go to Dynamic Simulation tab and set the values of Damp to 0.003, High Detail Solver to All Grids and Simulation Rate Scale to 1.200.

Step 2

Go to Container Properties tab and increase the Base Resolution to 50.

Step 3

Go to Lighting tab and turn on Self Shadow option and increase the value of Shadow Quality to 1. You can now see the self shadow of the smoke inside the viewport.

Step 4

To change the color of the smoke, go to Shading > Color tab and change the colour of the smoke by clicking on the Selected Color option.

Step 5

Go to Auto Resize tab and turn on Auto Resize option. The grid will now keep expanding according to the smoke expansion.

Step 6

Go to Content Details > Density tab and set the values of Buoyancy to 10, Dissipation to 0.500 and Noise to 0.100.

Step 7

Go to Velocity tab and set the values of Swirl to 4 and Noise to 0.100.

Step 8

Go to Turbulence tab and set the value of Strength to 0.025.

Step 9

Go to Shading tab and you can play with the Transparency value for the desired falloff transparency of the smoke as shown in the following image.

Step 10

Go to Shading Quality tab and set the value of Quality to 1.500.

Step 11

Go to Create > Lights > Directional Light and create a directional light in the scene as shown in the following image.

Understanding Particles and Dynamics in Maya—Part 9

Step 12

Keep the value of the Intensity as 1.5 and turn on Use Ray Trace Shadow option.

Understanding Particles and Dynamics in Maya—Part 9

Step 13

Go to Fluid Attributes tab and Increase the Density/ Voxel/ Sec value to 5.

Step 14

Go to Container Properties tab and Increase the Base Resolution to 250. For final production quality rendering, you can increase this value to 400.

Step 15

Open Render Settings window. Choose Render Using as Mental Ray. Go to Shadows tab and choose Shadow Method as Segments.
