This page offers information about the Post tab in Chaos Vantage.
The Post tab allows control over the post-rendering effects such as Highlight burn, Contrast, Filmic Tonemap, LUTs, Bloom and Hue/Saturation.
Highlight burn – Applies exposure corrections to highlights in the image.
Contrast – Positive values push the colors away from the medium gray value to increase image contrast. Negative values push the colors closer to medium grey.
Filmic tonemap – Applies a parametric mapping curve and gamma correction.
Type – Specifies the type of curves used for the tone mapping. You can choose between Hable and AMPAS.
Gamma – Specifies the gamma correction. It is applied before the operator.
Shoulder strength – Determines how sharp the shoulder is. Higher values sharpen the shoulder, which results in an overall brighter image.
Linear strength – Determines the strength of the effect from changing Linear angle.
Linear angle – Determines the angle of the curve at the base. Higher values increase the angle.
Toe Strength – Low to mid tone compression. Higher values darken the low and mid tones.
White point – The intensity, which gets mapped to 1. This parameter scales the whole curve evenly.
LUT – Applies a lookup table file to the scene. LUT can also be toggled on/off from the top toolbar icon().
Amount – Specifies the LUT weight, where 0 is no LUT effect and a value of 1.0 applies fully the effect.
Load LUT file... – Loads a LUT (lookup table) file.
Color space –Specifies the color space for the loaded LUT file .
Linear – The loaded LUT file will be interpreted in linear color space.
sRGB – The loaded LUT file will be interpreted in sRGB color space.
V-Ray Log. – The loaded LUT file will be interpreted in a V-Ray logarithmic color space.
Bloom – Applies bloom to the scene. Bloom can be also be toggled on/off from the top toolbar icon(
Intensity – Multiplier for the bloom source. Increasing the value can boost the effect.
Threshold – Sets a minimum value for the rendered pixels to be considered as lens effects source. The Bloom will be generated only regarding pixels with larger value than the specified threshold.
Iterations (spread) – Specifies the size of the bloom spread. Larger values increase the spread but impact performance.
Hue / Saturation – Applies HSL transformation on the image colors.
Hue – Changes the overall hue of the image colors (grey colors remain intact).
Saturation – Specifies the image colors' intensities. Positive values produce a more vibrant, saturated image while negative values desaturate and dull the image colors.
Lightness – Adds or removes white from the image. Positive values add white to the image, making it lighter. Negative values remove white from the image, making it darker.
Chromatic Aberration – Applies chromatic aberration effect to the scene.
Value – Specifies the amount of chromatic distortion from the center to the edges of the viewport.
