Godrays

Godrays is an intresting visual effect noticed when the light beam is obstructued by clouds or an object. The effect is controled by the settings below.

Property	Function
Enabled	Enable state of this effect. This is a static and performance sensitive parameter.
Resolution	The resolution of the internal render textures used for god rays rendering. Lower values are fine since rays usually blurry. This is a static and performance sensitive parameter.
Backlighting	Whether to render god rays when the sun is behind objects. This effect is quite inaccurate(especially for clouds) and not usually visually pleasing.
Blur Iterations	The number of blur iterations applied to the god rays. Default value of 2 is fine. Adjust only if necessary (e.g noticing banding artifacts). This is a performance sensitive parameter
Blur Spread	The blur spread applied to the god rays per iteration. Use the Frame Debugger to find a good balance between 'BlurIterations' and 'BlurSpread' depending on your performance, quality and visual requirements.
Day Intensity	The intensity of the rays at day time.
Night Intensity	The intensity of the rays at night time.
Contrast	The contrast of the god rays. Higher values result in more defined rays.
Anti-Flickering	Whether to apply a temporal filter to the god rays to reduce flickering.
Anti-Flickering Strength	The strength of the anti-flickering filter. Higher values result in smoother rays but more ghosting.
Geometry Rays Intensity	Intensity multiplier for rays on top of a geometry.
Geometry Rays Color	Color multiplier for rays on top of a geometry.
