Wet and rainy environment. I haven't quite worked out all the kinks but this is pretty good. An improved wet terrain from my last one, an object "wettener" shader and a rain shader. Included a map showing it all together in Wet Environment/Maps. Also the mud material and skybox I used in the map. Create a pivot and attach the wet.lua script. Drag a material to your terrain platform and attach wetterrain.lua script. Put rain.lua in the PostEffects box under the root in the Scene tab.
