Bump Maps - Arnold for 3ds Max

Bump2d

Provides bump mapping based on a 2d texture map.

_{noise -> bump2d -> standard_surface.normal}

Bump3d

Provides bump mapping based on a 3d input. Bump3D works by evaluating the bump input at different points (P + epsilon, P + epsilon, P + epsilon).

_{noise -> bump3d -> standard_surface.normal}

Normal Map

Normal mapping works by replacing the interpolated surface normal by the one evaluated from an RGB texture, where each channel (Red, Green, Blue) corresponds to the X, Y, and Z coordinates of the surface normal.
