Color Bleeding (Rasterization)

CB Layer Size

Color bleeding is rendered using its own resolution (similar to ambient occlusion), this resolution affects performance and quality greatly. Using this parameter it can be adjusted to match the current needs for performance or quality. The value is a simple multiplier where 1 means that the resolution is the same as output resolution.

CB Directions

Adjusting this parameter changes the quality/performance of CB. Setting this value too high when not needed can have a notable performance hit. This attribute represents number of directions per shaded pixel when casting rays to compute CB. The default        value is usually enough for most cases. Keep this value low as possible to improve performance.

CB Steps

Number of rays cast per direction (see CB Directions above). The default value is usually enough for most cases. Keep this value low as possible to improve performance.

CB Radius

Maximum distance to 'bleeders' that should be taken into account.

CB Attenuation

Rate of bleeding attenuation. Color bleeding attenuates with distance from shaded pixel, ie. distant objects do not bleed as much as closer objects.

CB Angle Bias

Minimum angle between surfaces to have CB between them. In some cases CB can form in places where it is not desired, eg. two almost collinear surfaces right next to each other. In such cases it is good to increase angle bias to values that gives the desired result.

CB Blur Radius

Resulting CB values are blurred together with respect to objects and scene depth to remove noise. This attribute tells how much blur should be applied, the blurring can be also disabled by setting the value to zero if noisy CB is what is wanted.

CB Blur Sharpness

Blur sharpness value affects the way blur is applied to the resulting CB layer. Blurring technique takes different objects and their depth into account so CB from one object is not blurred with CB from another object right next to it. Higher values result in more strict rule to not blur pixels from different depths.

CB Post Apply Intensity

Using this parameter CB layer is applied to the scene with given intensity.
