Nút Độ Gồ Ghề -- Bump Node

Bump Node.

The Bump node generates a perturbed normal from a height texture, for bump mapping. The height value will be sampled at the shading point and two nearby points on the surface to determine the local direction of the normal.

Đầu Vào -- Inputs

Sức Mạnh/Cường Độ -- Strength

Strength of the bump mapping effect, interpolating between no bump mapping and full bump mapping.

Khoảng Cách -- Distance

Multiplier for the height value to control the overall distance for bump mapping.

Chiều Cao -- Height

Scalar value giving the height offset from the surface at the shading point; this is where you plug in textures.

Pháp Tuyến -- Normal

Standard normal input.

Tính Chất -- Properties

Đảo Nghịch -- Invert

Invert the bump mapping, to displace into the surface instead of out.

Đầu Ra -- Outputs

Pháp Tuyến -- Normal

Đầu ra pháp tuyến chuẩn.

Ví Dụ -- Examples

The above node setup will only bump the diffuse part of the shader, simulating a bumpy diffuse surface coated with a smooth glossy "glaze" layer.
