RT Ambient Occlusion
Renders Ambient Occlusion with Ray Tracing
RT Ambient Occlusion
Method #
This node simulates ambient occlusion by casting a large number of rays in random directions in a sphere or hemisphere from each point on the screen, and determining what percentage of them hit something before reaching the extent of the bounding sphere.
Raytracing will need to be enabled on the root node for this node to work.
Parameters
These properties control the core behaviours of the node.
Parameter Details
Blend Mode Sets blend mode type.
- Add : Adds the lighting.
- Multiply Ambient : Multiplies with ambient lighting.
- Multiply Ambient + Lighting : Multiplies with both ambient and lighting.
Blend amount How much the light is blended with the ambient occlusion
Radius Radius of the ambient occlusion
Samples Sets umber of samples taken
Ray Bias Ray bias of the shadows
