Developer Orbx has provided some information regarding the forthcoming patch for their TrueEarth US Oregon Package for X-Plane 11.
Some users of this scenery have mentioned colour issues within the urban areas of Oregon. Orbx has taken to their forum to reassure users that they are aware of the blue and purple tones and are working on creating new ortho imagery from various sources to rectify these anomalies. Orbx has singled out the 2015 NAIP source imagery for Oregon as the main issue as this adds too much blue and red tone to the image. Whilst correcting the colours of most of the state prior to release, some urban areas did not respond well to their filters.
