Map scape is a simple free to use map creation tool made with dbp.
With light mapping and easy object manipulation makes creating maps fast and easy.
have also simple terrain editing functions.
Can export to .x and .dbo files.
Urho3D users can use AssetImporter for .x files but these files have only
vertex.position,vertex.normals and vertex.texcoord0
I made .DBO Converter (source-code included) for Urho3D where can export
vertex.position,vertex.normals,vertex.texcoord0,vertex.texcoord1
and vertex.color for terrainsplat information
there i also made shaders and examples for it.
