well with the floating new update can we have puddles and aquaplaning, that would be cool, rain that builds up surface water would be even cooler!
I think that it would be pretty easy to set up a "terrain paint" type that has shallow depth like the mud that makes you sink and a clear blueish texture. Even though the water doesn't splash or anything it would still be cool. Although, reflections would be a different story. You would have to do something similar to reflections on a window or regular water. Or you could just make a small water block and sink the terrain and actually make a physical puddle on the edge of the road. Who agrees?
ITS POSSIBLE im experimenting with it right now. i put a river over a road in eca then made boyuncy high. time to fine tune and see how good i can get it
