You can see wet-dry maps in action in a downloadable scene: → "Splash to Wall Wetmaps".
RealFlow | Cinema 4D is able to read an object's UVW coordinates for applying textures or creating wet-dry maps. If the UVW coordinates are wrong or not present you will not get the expected results and the calculation of wet-dry maps might fail. Here is some more information on them:
...
- Make sure that the object has proper UVW coordinates.
- Create a material, apply it to the object, and select the "Color" channel (or any other channel a channel with image support , (except "Normal").
- From "Texture" choose "RealFlow WetMap".
...
- To see the maps at simulation time, go to the material's "Editor" tab and enable "Animate Preview":
Improving Quality
The object's For this optional step, the object requires a → "Volume" tag. The → "Cell Size" value determines the quality of the fluid-object interaction. If you can see gaps between particles and surface decrease this value:
- By default, "Cell Size" is calculated automatically, based on your → "Collision Geometry Detail" selection.
- When you disable the "Cell Size" parameter's "Auto" option you are able to enter a custom value.
