Testing river mesh generation,
\nidea is from forum topic: http:\/\/forum.unity3d.com\/threads\/225561-Is-there-any-way-to-have-a-river-flow-without-flow-maps?p=1502875<\/a><\/p>\n

Webplayer:<\/strong>
\n http:\/\/unitycoder.com\/upload\/demos\/RiverMeshMakerUnity\/<\/a><\/p>\n

Features:<\/strong>
\n– Start point, length, width, segment length, adjustable x-position (middle of the river), in the screenshot using Mathf.Cos(#)
\n– Each piece\/segment has UV (0,0 to 1,1) so can scroll the texture to Y direction..<\/p>\n

Todo:<\/strong>
\n– Terrain editor plugin (to dig river in unity terrain object)<\/p>\n

Problems:<\/strong>
\n– Would need better water shader..
\n– Start of the river bit bugged
\n– Tried baking flow direction to vertex colors, but couldnt get the angles right..
\n– Visible tiling on slices (depends on shader used.. but should blend them somehow)
\n– vertical segment start and end have duplicate vertices, not needed..<\/p>\n

Image#2:<\/strong> mesh geometry, made from 4 vertices per segment<\/p>\n
