- When installing a 3P via use_prebuilt_binary it will pass --installdir=${AUTOBUILD_INSTALL_DIR} to

gamma > 1.0f; sun_norm > 0.0f, 1.0f, 0.0f, 1.0f; cloud_shadow > 1.0f; dome_radius > 1.0f; dome_offset > 1.0f
Which probably made the original memset produce the wrong result anyway as it differs from the value the
LLVOSky set (the default ctor of AtmosphericsVars) vs what the memset would produce in case of a force update (all 0s).
