Does anyone here know how to scale a SceneNode texure, like repeating it 20 or 30 times! ...

I only found in the tutorials how to scale a TerrainSceneNode texure by using:

Myterrain->setscale(....)

But i want to scale it for a different SceneNode rather than the terrainSceceNode

Change the texture coords of the mesh such that instead of going from 0 to 1 they go from 0 to 20 or 30 (i.e. scale the coords).
