The Bump and Normal Mapping rollout is part of the VRayMtl parameters. 


## **Parameters**

---

> ℹ️ V-Ray GPU supports only **Bump Map**,** Normal map in tangent space**, and **Normal map in world space** map types.

**Map** – Allows the user to connect a texture for the bump or normal map. Leaving this unconnected turns off bump/normal mapping.

> ⚠️ It is not recommended to use color-corrected textures as a normal map. If such a bitmap is used, V-Ray prints a warning for unexpected results.

**Bump Mult** – A multiplier for the bump map effect.

**Bump Delta Scale** – This parameter can be decreased to sharpen the bump and increased to blur it. Available only when **Map Type** is set to **Bump Map**.

**Resolution-Independent Bump** – Ensures consistency of the bump effect regardless of the camera’s distance or rendering resolution. The texture’s details don’t vary when zooming in or out on the object. Note that when using a **File **texture, you must set the **Filter type** to **Off**.
