Houdini 19.0 Nodes VOP nodes

MtlX Ambientocclusion VOP node

On this page

Compute the ambient occlusion at the current surface point, returning a scalar value between 0 and 1. Ambient occlusion represents the accessibility of each surface point to ambient lighting, with larger values representing greater accessibility to light. This node must be of type float.

Parameters

coneangle

The half-angle of a cone about the surface normal, within which geometric surface features are considered as potential occluders. The unit for this input is degrees, and its default value is 90.0 (full hemisphere).

maxdistance

The maximum distance from the surface point at which geometric surface features are considered as potential occluders. Defaults to 1e38, e.g. 'unlimited'.
