Convert displacement to polygons iam dealing with this problem. I try to change from Maya to Blender and one thing is making me nuts. The displacement. I use it a lot to create geometry. So far I could not handle that in blender.
Is there any advice to do this properly?

There are three pictures, in the first one i try displacement texture but it does not affect the geometry at all and I dont now how to convert it.
Second one is how its done in Maya and how i do this.
Third one is done via modificator which happend to be bad.
As you're using the cube's UV, in the modifier you need to choose Texture Coordinates > UV. Also, reduce the modifier's Strength, and put one Subsurf above and one under the Displacement with subdivisions of 2, this will make it smooth nicely.
