Set fluid attribute ramps

Some fluid attributes have ramps that let you remap the raw fluid properties into the values used when rendering. The following fluid attributes are set using ramps:

• Environment
• Color
• Incandescence
• Opacity
• Wave Height on the Ocean Shader/Texture node

To set an attribute ramp

1. In the scene view, select the fluid object for which you want to set an attribute ramp.
2. In the Attribute Editor, select the fluidShape tab.
3. In the Attribute Editor, locate the attribute ramp you want set, and then create the ramp by setting values for Selected Position and Selected Value.

   For more information on setting ramp values, see Set attributes using ramps.

4. Set an Interpolation method to specify how values blend between each Selected Position (point) on the ramp.
5. Set the ramp’s Input to specify which fluid property is used to map the input attribute value.

   For example, a grayscale ramp and a color ramp with a black, orange, and yellow mapped to Density appear similar to the following:

   
6. Set the ramp’s Input Bias.
