Apply modifier on only one face...

Hi Guys ! Good friday to all !

Is someone could explain to me, step by step how to apply any modifier on only one face of a cube or something else ?

I will greatly appreciate ! Thanks in advance !

The Poly Select modifier should do the trick. Note that the object must be an Editable Poly. Basically, add Poly Select, select faces/edges/vertex/elements, and while the selection is active add another modifier to affect only the selected parts.

It was an “Editable Mesh”, I convert it to an “Editable Poly”…

But ! I dont know why, the “Vraydisplacemod” is applied to all the object…

Like this…

In this case, that method won’t work. However, activating the “Use object mtl” in the VRayDisplacement options and using a Multi/Sub-Object shader, where only a certain ID has a displacement map plugged will work. Check the attached scene.
