* '''Elevation:''' The water uses a separately deformable heightmap, so that the water mesh can vary in height throughout the map. When the watermap is lower than the terrainmap, we have dry land; when higher, a water area occurs in that space.  * '''Terrains:''' Like cliffs, waters consist of several textures for the different areas of the water object, and so things like what units can move over water are determined by the terrains used.  * '''Blending:''' The different water types need to blend in a natural way (eg shore into shallows into deep water). We can calculate this taking the distance between the terrain plane and water plane to create a viscosity factor (the greater the difference between the two heightmaps, the darker the water) and blend factor (how much deep water texture, how much shallow water texture). * '''Ripples:''' The water mesh should "shimmer" (deform motion on the surface and edges, with ripples and waves, noise distortion). It should be reflected and lit. * '''Slopes:''' We won't be able to have sharp drops in water elevation and make it look good (textures will be severely stretched). But then, they don't occur in nature all that often anyway. For things like waterfalls, we'll have waterfall gaia objects that we can place between two rivers of differing height to hide the sharp drop.  * '''Waves:''' Animated foam sprites on the water surface (eg AoM, War3) don't really fit the hyper-realistic art style that the artists want to achieve, so we won't do them. We'll distort the mesh along the shoreline instead, attempting to create mesh-based waves.[list]The sprite name of the icon to display for this water. ||'''Icon'''|| [[BR]]'''''BRIEF DESCRIPTION ::''''' The sprite name of the icon to display for this water.[[BR]][[BR]] ||'''Surface'''|| [[BR]]'''''BRIEF DESCRIPTION ::''''' The terrain object that gets placed on the surface of the water mesh.[[BR]][[BR]]Consists of two sub-tags: * '''Terrain:''' The name of the painted terrain object. * '''Area:''' The percentage of the water area that uses this texture (range 0..1). ||'''Bank'''|| [[BR]]'''''BRIEF DESCRIPTION ::''''' The terrain object that gets placed on the edge of the water (typically shallows).[[BR]][[BR]]Consists of two sub-tags: * '''Terrain:''' The name of the painted terrain object. * '''Area:''' The percentage of the water area that uses this texture (range 0..1). ||'''!OuterBank'''|| [[BR]]'''''BRIEF DESCRIPTION ::''''' The terrain object that gets placed on the outer edge of the water (typically the shore).[[BR]][[BR]]Consists of two sub-tags: * '''Terrain:''' The name of the painted terrain object. * '''Area:''' The percentage of the water area that uses this texture (range 0..1). ||'''Layer'''|| [[BR]]'''''BRIEF DESCRIPTION ::''''' A terrain that gets layered on the water when it reaches a certain depth. Layers occupy the same area as the "surface" terrain, just at a different depth.[[BR]][[BR]]A water can have any number of water terrain layers. These typically are only used for deep expanses of water (ie oceans). Rivers don't tend to have them, except maybe a "bottom" layer.[[BR]][[BR]]Consists of two sub-tags: * '''Terrain:''' The name of the painted terrain object. * '''Distance:''' The distance specifies how deep the water must be before this terrain is painted. The value "bottom" is a special distance that always appears on the very bottom of the water (it gets painted over the land mesh that's under the water), irrespective of depth. Note that if no bottom terrain is specified, the land will retain whatever texture was already applied when the water was painted. ||'''Colour'''|| [[BR]]'''''BRIEF DESCRIPTION ::''''' RGB colour of water transparency.[[BR]][[BR]]This is used to tint the water a certain colour eg light blue coastal water, or dark blue deep ocean water.
