A quick example of a displacement map.

You have a basic top of say 500k.

You add a texture to it, nothing added to the mesh size. Nothing really changes, it's just a flat texture.

You now add a weave displacement map.

That makes it look like the texture now has a weave texture on it, again, nothing has changed the mesh size.

I didn't make the displacement on the model, I just made it in a graphics program.

All displacement does to me is make areas stick up and other sections drop down.

All the best.
