Displacement – don’t move the floor

Adding displacement to your floor, it changes the position of its surface,
compenetrating all the geometry placed on it.

Just use the option “shift” to work fine:

CONCEPT

• The best solution to add displacement is VRayDisplacementMod (in “Modifier List”)
• For floors (or grounds) use 2D mapping
• To keep the position of your surface us Amount = X cm / Shift = -X cm
