- 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.
- The maps are not displayed If you have trouble seeing the maps at simulation time . If you want to see them you have to just render an appropriate frame.
- Wet maps can will be → cached together with the particle simulation, then . Then it is possible to post-processedprocess, and reappliedreapply the maps.
Follow these steps:
- Assign a "Collider" tag to an object, open RF Collider tag > WetMap, and make your → settings.
- Make sure that the object has proper UVW coordinates.
- Create a material and select the "Color" channel.
- From "Texture" choose "RealFlow WetMap Shader".
- Attach the material to the object.
Improving Quality
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.
...
- 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.
