Wet Cobbles Vertex Painting

In another post, I covered how the Wet Cobbles material was pieced together from research into materials.

This material is set up to take input from Vertex Painting. Basically this means that the amount that a certain colour is vertex painted onto certain areas of a model is the amount and areas where the effect will show.

This is demonstrated below, the effect is controlled by the Blue vertex paint channel, observe how each tile reacts to each paint configuration.





Fully Blue is dry, a slight fade to black gives a damp effect, more blotchy black areas gives a puddled look and 100% black is full flood.

Now that this effect is in place, the entire floor will need to be vertex painted to look wet and puddled in a natural way.

This is achieved by hiding most of the scene and leaving the floor visible while I work, so that objects and walls don't get in the way. Seen below is before I started properly painting, with just my experimental paints in place.



Then after a bit of work, I got some good effects and it to look natural.



And a bit of a Lit Preview:



The main complaint about this is that the Vertex Painting Editor does NOT support pen tablet pressure, so I had to set the flow quite low and build up the painting with the mouse gradually to get it to look natural.
