- You have to assign a → "Collider" tag to the object you want to make wet.
- The tag provides the parameters to control the map's quality and drying effects.
- RealFlow | Cinema 4D's wet maps are always squared.
- If you have trouble seeing To see the maps at simulation time just render an appropriate frame, go to the material's "Editor" tab and enable "Animate Preview".
- Wet maps will be → cached together with the particle simulation. Then it is possible to post-process, and reapply the maps.
...
- Make sure that the object has proper UVW coordinates.
- Create a material and select the "Color" channel (or any other channel with image support, except "Normal").
- From "Texture" choose "RealFlow WetMap Shader".
- Attach the material to the object.
...
- Select the material and open RealFlow WetMap Shader > WetMap Display.
- Adjust the colour gradient.
- Be aware that these colour changes are temporary only unless you → (re-)cache the simulation.
