Irrlicht Engine

What sould the detail map do?

Yeahh detail map ! did not know that irrlicht support this! how can i set a detail map ??

@Herr Müller

a detail map is a texture you put over your main texture many times as small tiles to get the impression of an hight detailed main texture. generally its only an black and white texture.

I know, what a detail map is doing in terrain engines, that work, but I thought that the Irrlicht Engine is doing something else with it, because nothing happened when using it.

When creating an ITerrainSceneNode with the ISceneManager you can give an ITexture as detailmap. (guess it's the 4th parameter)
