I have been trying to create a wetmap using vertex map fields without much luck and am wondering if that is possible. I did watch a quick tip by Jonas Pilz, but he simply tied a linear field to a rising and falling ocean. I have a scene with a river with ripples and some sandbars protruding where I want a wetmap at the dynamic intersections, hopefully getting some dynamic circles. It’s a Redshift scene, so I am fine with the texturing once I get the wetmap working.
I have created a very simplified example attached, and my last try with the vertex map on the riverbed. I set the riverbed texture to just show the wetmap when rendered, which you will see is static and seems to ignore the animated noise displacement of the river.
Thanks for any help, even to say this is not possible (I can do it with X-particles with a fluid sim, but this would be much easier and less taxing for a heavy scene if it is possible). Not being an ace at fields yet, details such as point or surface, blending modes, remap or not, etc. would be greatly appreciated.
