Do you mean triangle, or vertex? It would be fairly straightforward to modify the terrain extension to include a per-vertex color channel. Also, depending on your use case, you might want to consider just using another texture. |

or calculate the color directly in the shader using the y value |

i created an image and replaced to detail.jpg but it didn't work. on the screen i see detail.jpg tiled i want to stretch detail.jpg to whole terrain so i can give colors higher hills to red lowers to green is there any way to implement this? and i am newbie in horde3d and i dont know syntax of the shader.xml so i couldn't choose colors in the shader.xml is there any documentation about the horde3d's xml files (shader.xml , scene.xml etc) and its functions ? |

You are in a little bit over you head at this point. Start off by learning GLSL (OpenGL Shader Language), which is the code present in the shader.xml files. There are many tutorials on the web, just use google, or grab a book from your local library.
