HeightMap based on the main texture

Hello,

I have a plane on which I apply a grayscale texture.
What I would like is a simple shader that adds relief to the plane according to the texture (like with a Bumped Diffuse shader). All black zones of the plane will have a different depth than white zones.
Is it possible?

Might help…

Edit: updated to Answer, glad that worked.

you need to create normal map and use normal map shader.

search google for “height map to normal map converter”…
