HBAO node¶
The HBAO node generates a horizon based ambient occlusion texture from its input.
Inputs¶
The HBAO node accepts a single greyscale 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.
