Does Blender do height maps?

Hello

I would like to create a floor height map with blender for irrlicht engine,  i can just create a flat plane and put texture on it , is this a good idea?

are there better softwares outthere (free) for it?

Subdivide the plane enough, and then hit noise button (in edit mode) as many times as needed ,and watch the vertices rising up.

Hope it’s what you what you needed.

Theres a plugin on my page that does heightmaps with better numeric input.
