This page provides information on the Bump Material. Overview The VRayBumpMtl gives the ability to add bump map and normal map effects when using any material. Simply connect a material into the VRayBumpMtl node to add additional bump or normal map functionality. Stacking multiple VRayBumpMtl nodes together can create a more complex surface material by allowing the use of several bump and or normal maps together easily. ||Material Editor|| >  Map Browser  >  Materials  >  V-Ray  >  V-RayBumpMtl © Milo Liao Parameters Base material  – Allows you to select the base material to which the bump effect is added.
