List of CVARS:
|
|
|
|
r_HDR_enableDebugMode
|
|
r_HDR_debugTextureIndex
|
|
r_HDR_postProcess
|
|
r_HDR_middleGray
|
|
r_HDR_brightPassThreshold
|
|
r_HDR_brightPassOffset
|
|
r_HDR_min_luminance
|
|
r_HDR_max_luminance
|
|
r_HDR_eyeAdjustmentDelay
|
|
r_HDR_colorCurveBias
|
|
r_HDR_maxColorIntensity
|
|
r_HDR_bloomIntensity
|
|
|
|
|
|
r_HDR_enableDebugMode (Integer)
|
|
default value 0
|
|
Shows all the textures generated for HDR postprocess.
|
|
1: Shows all textures (Endecoded), namely: 64x Downscaled scene image, 64x64 luminance texture (stores averaged scene luminance), 4x4 luminance texture, 1x1 adapted luminance texture, bloom result texture.
|
|
2: Decodes and shows all textures
|
|
|
|
r_HDR_debugTextureIndex (Integer)
|
|
default value 0
|
|
Show intermediate textures used for HDR postprocess
|
|
0: Off.
|
|
1: scene Image(64x Scaled down)
|
|
2: Result of first bloom pass.
|
|
3: Result of second bloom pass.
|
|
|
|
r_HDR_postProcess (Bool)
|
|
default value 1
|
|
Activates HDR tone mapping and bloom
|
|
|
|
r_HDR_brightPassThreshold (Float)
|
|
default value 5.0
|
|
brightness threshold for Bright-pass. E.g. color intensities beyond 5.0 will be bloomed and hence only very bright areas would qualify for blooming.
|
|
|
|
r_HDR_brightPassOffset (Float)
|
|
default value 10.0
|
|
Brightness offset for bright pass. E.g. Color intensities beyond r_HDR_brightPassThreshold will receive a nice gradually faded bloom from dark to bright giving color intensity of 10.0 the brightest bloom. To get a good understanding, set r_debugTextureIndex to 2 or 3 and then change this value to visualize the bloom image.
|
|
|
|
r_HDR_middleGray (Float)
|
|
default value 0.08
|
|
Middle gray value for overall scene ( Range 0 - 1) . Higher the value, brighter the scene.
|
|
|
|
r_HDR_min_luminance (Float)
|
|
default value 0.06
|
|
Measured luminance of the scene is restricted to this value to control how bright a lit area should get when standing in complete dark areas.
|
|
|
|
r_HDR_max_luminance (Float)
|
|
default value 0.22
|
|
Luminance is restricted to this value to control darkness when in super-bright areas. E.g. If you are looking at a very bright sky everything else around will get darker. This variable lets you control how much darker the surrounding should get when looking at full bright areas.
|
|
|
|
r_HDR_eyeAdjustmentDelay (Float)
|
|
default value 1.6
|
|
Total time in second taken to adjust eye exposure.
|
|
|
|
r_HDR_colorCurveBias (Float)
|
|
default value 0.3
|
|
Applies an exponential S-Shaped color curve to final pass (range 0 to 1), E.g. 1.0 = color curve fully applied , 0.0 = No color curve
|
|
See following 2d graph to grasp the working of color-curve bias.
|
|
|
|
|
|
r_HDR_maxColorIntensity (Float)
|
|
default value 3.0
|
|
Adjusting this value will cause color burnout of high dynamic range values going beyond 255 in a controllable fashion (range 0.0 - 256.0). This step is performed while bringing the HDR values into displayable range (0-255), also known as tone mapping.
|
|
Higher values reduces the contrast, lower values increases the contrast.
|
|
|
|
See Example Images:
|
|
|
|
|
|
|
|
r_HDR_bloomIntensity (Float)
|
|
default value 1.0
|
|
Adjusts the Bloom intensity. This CVAR is not being used yet.
