By changing wind speed in “TrueSkySample.cpp” (SimulDirectX11Sample_MD) like this:

    cloudOpt.windSpeedMS = vec3(100.01f,0.0f,0.0f);

With TrueSkySDK 4.3.e522695f8_x64_v142 -> The wind works as expected and move the clouds.
With latest TrueSkySDK 4.3.0857db303_x64_v143 -> The wind doesn’t move the clouds.
Is there any trick to get back a correct wind vs clouds behavior ?
