Getting rid of high‐altitude clouds - 5mods/tutorials GitHub Wiki
You can definitely remove them by editing 'clouds.xml' Usually here: ...\Grand Theft Auto V\mods\common.rpf\data\clouds.xml
Note: Use Ctrl+F3 in OpenIV to make sure you don't also have one in 'update.rpf' that will be overriding that one in 'common.rpf'.
Once you find the correct file loaded by the game, edit it & remove all the blocks of data with 'altitude' in the '' lines.
The ones like this:
<Item>
<mFilename>cloudhat_altitude_med_b</mFilename>
<mCostFactor value="0.000000" />
<mRotationScale value="0.500000" />
<mCamPositionScalerAdjust value="1.000000" />
<mTransitionInTimePercent value="0.400000" />
<mTransitionOutTimePercent value="0.400000" />
<mTransitionInDelayPercent value="0.000000" />
<mTransitionOutDelayPercent value="0.000000" />
<mHeightTigger value="800.000000" />
<mHeightFadeRange value="400.000000" />
</Item>That should get rid of them horrible clouds.
