DEVELOPMENT ROADMAP
All the items listed in the roadmap are sorted by priority Click on the icon to see all the actions performed during the item development
KNOWN ISSUES This section contains all the known issues for the completed features These items are of the top priority but may not be resolved in the next update
	Known Issue	Precipitation follows camera
Known Issue Precipitation follows camera This will be fixed during future development.
	Known Issue	Snow coverage may appear in the regions where no snowfall encountered recently
Known Issue Snow coverage may appear in the regions where no snowfall encountered recently Snow data is calculated and accumulated on the server over time. Some server parameters still require further tuning and this issue will be reduced as we continue with the server updates.
	Known Issue	Default X-Plane night triggers lights artifacts
Known Issue Default X-Plane night triggers lights artifacts Unfortunately xEnviro light blending is not fully compatible with default X-Plane rendering pipeline therefore some artifacts may appear at night. consider disabling Volumetric Lights Effect in xEnviro settings.
	Known Issue	Cloud edge artifacts
Known Issue Cloud edge artifacts In some situations visual artifacts may appear at the edges of clouds including dots, lines, random cutouts. This will be further refined in the future versions.
	Known Issue	Low level clouds may be combined
Known Issue Low level clouds may be combined We are changing the way xEnviro servers handle the weather conditions when several cloud layers develop in a relatively small volume. Example can be FEW007 SCT008 BKN009 reported. As of now such conditions force the local air parcels to shrink to a size when no visible moisture can be produced due to the short vertical travel distance for condensation particles and therefore insufficient gradients calculated. Temporary, instead of discarding these layers our servers try to combine them onto a single layer of uneven base. This is scheduled to be revised and further refined during the next server code upgrade.
