RealFlow allows you to wet your objects by "painting" with particles´ collision over its UVs

If you want to wet an object, it should have its UVs setup from your 3D package before being imported into RealFlow. This is a MUST.
We have created this simple object wich has its UVs set to work.

 

To see the texture applied to an object in RealFlow, change the display mode to Textured.
To make that, right click on any part of the viewport and select Shading->textured. Your object will turn to black.

The wet texture is a property of the objects, you can activate it in the Texture tab of your object.
Five values are activated and your object will turn to black.

Filter Loops: The wet/dry texture performs a blur filter to the image in order to make it less crispy. Filter Loops control the quality of this applied blur.
Filter Strength: Controls the amount of blur.
Pixel Strength: Controls the initial value, in grayscale, of the pixels colored in the process, before the blur filter is applied.
Ageing: Control the dry velocity of the texture.
