Maxwell Render has three methods of displacement:

Adding displacement to a material
A Only one displacement component can be added to the material (only one component per layer is allowed) by right-clicking , to ensure the continuity and physical integrity of the surface. To add it simply right-click in the Layers list area of the Material editor , or from the Edit menu of the Material Editor. Please note that, although you can have several displacement components in a material, only one of them will be selected for rendering (to ensure the continuity and physical integrity of the surface). You can specify which one you would like to use by clicking on the Material Properties row in the Layers list. It can be useful to have several Displacement components in one material for quickly switching between different sets of displacement settings.and choose the Displacement component from the dropdown menu (or using the Edit menu).

To use displacement, you need an object with UVs and a displacement texture. The texture is similar to a usual grayscale bump map, with different shades of gray to describe elevation levels. Lighter grays will raise the geometry and darker grays will create cavities. Vector displacement maps are in color and 32bits, where red, green and blue describe both elevation and direction.
