Thanks for the bug report.
The culprit as you guessed is some of the 3D cloud changes. The attached patch
reverts one of my changes which ensured that the 3D clouds were updated with
METAR. Unfortunately this had the side-effect of over-writing the environment
properties, and therefore nuking the interpolation work.
The patch below backs out that change. Unfortunately this means the change
to the cloud coverage due to changing METAR will not be reflected in the 3D
clouds
(2D clouds are unaffected). Unfortunately I don't think it will be possible to
fix
this before the release.
Could someone please commit this? Thanks.
