Stylized Water 2
Vertex colors are vertex attributes just like position, normals and UV’s are. These can used to drive some of the shader’s behaviour. Vertex colors can be painted in any of the populair 3D tools, but also in the editor using PolyBrush.
Red channel (intersection foam):
For this to take effect, the “Gradient source” under the Intersection tab should be set to either “Vertex color”, or “Both”. For the best effect, make sure you’re not painting 100% red. The effect needs a gradient to work with.
Green channel (opacity):
The “Vertex color opacity” checkbox must be ticked under the Color tab.
The “vertex color flattening” checkbox must be ticked under the Waves tab
This makes it possible to have high waves in one part of the environment, while retaining flat water at the shoreline. Note that this does not affect Buoyancy , which will still read the original wave height.
If River Mode is enabled, the Blue vertex color channel can be used to add surface foam.
