Справка Houdini на русском Shelf tools

Paint Temperature shelf tool

This tool lets you paint higher or lower temperature on geometry in your fire simulation.

Using Paint Temperature

  1. Create a fire simulation.

  2. Click the Resimulate menu in the bottom right corner of Houdini and turn off the Enable Simulation option.

    Note

    The icon may be greyed out . Once you turn off this option the icon will change to a "do not" symbol.

  3. In the current DopNetwork, find the Gas Burn Geometry node (usually called burnsolver) for the object you want to paint and change the Ignition Temperature to 0.01 and Ignition Range to 0.001.

    In this example we modified burnsolver1 which was the Gas Burn Geometry for the torus object.

  4. Click the Paint Temperature tool on the Volume Fluids shelf.

  5. Select the object you want to paint and press Enter to confirm your selection.

  6. Set the value to paint in the Operation Controls toolbar, and drag the brush over the surface to paint it.

    Tip

    You can change the Radius of your brush by holding ⇧ Shift + and dragging or by changing the value in the Operation Controls toolbar. You can also alter the Opacity in the Operation Controls toolbar.

  7. Click the "do not" icon in the bottom right corner of Houdini and turn the Enable Simulation option back on.

The torus object burns quicker in places where the painted temperature is higher than the Ignition Temperature on the burnsolver (Gas Burn Geometry) node. In this example, the far side of the torus ignites before the side closer to the sphere because the ignition temperature is higher.

Note

Heat is transferred within the smoke box, so an object can become hot enough to ignite before a flame from another object comes in contact with it.
