HBAO node — Material Maker documentation

# HBAO node

The HBAO node generates a horizon based ambient occlusion texture from its input.

## Inputs

The HBAO node accepts a single grayscale image as input, interpreted as a heightmap.

## Outputs

The HBAO node outputs the generated oclusion map.

## Parameters

The HBAO node has the following parameters:

- the size of the ambient occlusion map

- the radius of affected range of point in UV size

- the angle bias - minimum angle on heightmap for AO to occur. Angle is calculated in UV space, where depth (grayscale input) is scaled by depth scale parameter

- the depth scale value controls cacluated normals & tangents by scaling range of values of grayscale input

- the quality controls number of steps per direction sampling

- the intensity of the generated ambient occlusion map

## Notes

This node outputs an image that has a fixed size.
