How to make a custom sculpting brush using the bake function Made two objects a plane and a pyramid then bake using the displacement mode with select to active.


The output from the bake is grey for the plane and flat white for the pyramid. When the image texture is used as a sculpt brush it doesn't create the same pyramid shape that was used for the bake. Don't know what I have done wrong could I have some help please.
I really don't think you can have such a deep point on a displacement texture. That's why it just bakes a white square. Your brush is essentially just a square brush. 

I quickly made an example of how the texture should actually look like. It's not precise but it's to give you an idea.
