Simulation of wetting can be used in rendering for blending of wet and dry materials depending on which parts of a geometry have been in contact with the simulated liquid. Wetting can also change the behavior of simulated viscous liquid and make it stick to geometries. The wetting simulation produces a particle system called WetMap. It can be rendered using a Particle Texture map which blends between a wet and a dry surface material. |

The Active Bodies simulation currently supports interaction between scene geometry and the Phoenix Liquid Simulator. When an object is selected as an Active Body, the simulation both influences and is influenced by the Active Body's movement. Mutual interaction between the Active Bodies themselves is not supported yet. Interaction between Active Bodies and the Phoenix Fire/Smoke Simulator is not supported. For in-depth information on Active Bodies, please check the Active Bodies Setup Guide. |

Texture UVW

The main purpose of the Texture UVW feature is to provide dynamic UVW coordinates for texture mapping that follow the simulation. If such simulated texture coordinates are not present for mapping, textures assigned to your simulation will appear static, with the simulated content moving through the image. This undesired behavior is often referred to as 'texture swimming'. UVW coordinates are generated by simulating an additional Texture UVW Grid Channel which has to be enabled under the Output rollout for the settings below to have any effect. The custom UVW texture coordinates can be used for advanced render-time effects, such as recoloring of mixing fluids, modifying the opacity or fire intensity with a naturally moving texture, or natural movement of displacement over fire/smoke and liquid surfaces. Some examples uses are:
The Texture UVW channel values represent the UVW coordinates of each Cell in the Simulator, with a range of [ 0 - 1 ]. The channel is initialized when a simulation is started in one of two ways:
