大佬们，求助！这是咋回事啊？

灵魂之黯

刷了草地远景之后近景和远景之间有一段区域啥也没有，是我设置得有问题吗？

fGrassFadeRange=14128
fGrassWindMagnitudeMax=125
fGrassWindMagnitudeMin=5
iGrassCellRadius=2
iMaxGrassTypesPerTexure=15
iMinGrassSize=40
SkyrimPrefs.ini
[Grass]
fGrassFadeRange=14128
fGrassMaxStartFadeDistance=6144.0000
fGrassMinStartFadeDistance=0.0000

fGrassStartFadeDistance=6144.0000
GrassControl.config.txt
UseGrassCache = True
ExtendGrassDistance = True
ExtendGrassCount = False
EnsureMaxGrassTypesPerTextureSetting = 15
