The HDRBloomTonemap effect provides two features:
bloomThreshold : real |
Sets the threshold for the bloom effect. Any part of the scene brighter than this value will bloom. A value of
1.0
corresponds to white. Lowering this value causes more areas of the rendered scene to bloom. At a value of
0.0
everything in the scene blooms. The range is
[0...1]
。默认值为
1
.
blurFalloff : real |
Adjusts the amount of bloom. Lower values result in a stronger bloom effect, and higher values make the effect more subtle. The range is
[0...10]
。默认值为
0
.
channelThreshold : real |
Specifies the white point for the image. There is usually no need to adjust this. The range is
[0...1]
。默认值为
1
.
exposure : real |
Sets a linear multiplier on the lighting, brightening, or darkening the image overall. A value of
0.0
causes no adjustment to the image. The range is
[-9...9]
。默认值为
0
.
gamma : real |
Affects the non-linear curve of the lighting. Higher values increase the exposure of mid tones, lightening the image and decreasing the contrast. A value of
1.0
causes no adjustment to the image. Sensible values are in the range
[0.1...4]
。默认值为
1
.
tonemappingLerp : real |
Specifies the strength of the overall bloom effect. There is usually no need to adjust this. The range is
[0...1]
,采用
0
being no blur and
1
being full bloom. The default value is
1
