Because I wasn't 100% glad about it I tried to optimize my results.Why not just use a glass shader?In the second picture you see the result of a normal glass material being used as a water shader. The problem is that water absorbs light the more the light travels trough it. A normal glass shader will show every object regardless of how deep the object is positioned. My old shader simply just blurred that object, the new one doesn't.How does it work?Each material is given a Node-Group called "Fake_Volume". Instead of actually computing volumetrics the object is simpy rendered a gradient transparency below the water surface.Falloff: Influences the visibility ramp below water surfaceTurbity: Overall visibility below water surfaceColor Influence: Influence of the water colorColor Depth: Influences the water color rampWater Color: Color of the water below the surfaceCamera Falloff: Visibility falloff based on the view distanceLatest Change on 2014/01/15, 11:54:53Added Camera Falloff ++ Layout-Improvements inside the Node-Group
