here a image i just did in the DEMO softwae, cant save as it been edited out coz it being a demo verion.

huge landscapes in REAL-TIME with WYSIWYG results. Use up to 6 individual textures to directly paint your landscape with no loss of quality or speed and automatic blending. Export worlds in DirectX .x format for use in your 3D engine. Tested with Quest3D, 3D Game Studio, Dark Basic Pro, Blitz3D, Ultimate Unwrap (excellent for file conversion if you can't use .x !) and should work in any 3D engine capable of loading/importing standard .x files! Export worlds to .b3d format. These can be automatically 'sliced' into 4 zones to aid with custom culling routines. Automatic optimization usually reduces polycount by about 50% (even better for .x) on exported models! Set the suns position, then lightmap the entire landscape within seconds. Use vertex colors to add even more variation to your creation. Add virtually limitless variation to your textures in realtime with no performance overhead. Intuitive & productive interface - Click a point on the landscape to see it transform instantly. AutoSmooth tool - automatically refine your work! Import / export heightmaps compatible with most other 3D (& CAD) software including 3D Game Studio, 3DS Max, Lightwave, Terragen, Blitz, etc... Placement of 'Props' (such as trees, buildings, waypoints) on the landscape Full world editor functionality (Load, position, scale, name, set to ground, rotate, clone, delete) Place multiple objects in seconds using a 'PlaceMap' Props can cast shadows on to the landscape
