Post Processing

Post ProcessingEffects such as Bloom and Glare that are applied after a scene has been rendered. effects are used to add various post-rendered effects to a rendered image. The post effects available in Octane For After Effects include Bloom, Glare, and Spectral Intensity/Shift.

The Post Processing effects are located in the Post Processing roll out of an OctaneRender Effect (Figure 1).

Figure 1: The Post Processing Parameters.


The Post Processing parameters:


This is a boolean value used to enable or disable post-processing effects on the resulting render. Post-processing is disabled by default.


Bloom Power
Controls the size of the glow originating from an emitter, the size of the halo of light originating from the sun, and/or concentrated light on reflective glossy materials - to add a bloom effect to the rendered image.


Glare Power
Controls the size of the visible rays originating from an emitter, the size of the glare originating from reflective glossy materials at a point where the concentration of light is at its highest - to add a glare effect to the rendered image.


Glare Ray Amount
Controls the number of visible rays radiated or reflected.


Glare Rotation Angle
This is used to adjust the rotation of the glare relative to the object. A glare angle of -90 and 90 results to one main horizontal glare, and a glare angle of 0 results to one main vertical glare.


Glare Blur
Controls the sharpness of the glare. Smaller values will result to a crisp linear glare and this is softened as the value is adjusted and set higher.


Spectral Intensity
Used to adjust the intensity distribution of the rays across a source. This affects the strength or weakness (brightness) of the radiant energy.


Spectral Shift
Used to adjust the displacement of the spectrum as the frequency of light emitted from a source changes affecting the visible spectrum relative to the source on the scene. The shift is evident by a color change, similar to the Doppler Effect, as the distance traveled by the ray from its source increases or decreases.
