Which Version of Photo Scenery do you have?
A brief history of VFR Scenery produced by Horizon Simulations, Playhorizon and Playsims..
Version 1 of Volumes 1-3 England and Wales was produced and marketed by Horizon Simulations. It was identifiable by requiring a serial number to complete installation. Version 1 was made using the original pre-sales FSX-SDK from Microsoft. With the advent of Service Packs 1, 2, Acceleration and Gold, Version One no longer functioned correctly and was replaced by Version 2 of Volumes 1-3. Original registered users of Version 1 were sold at nominal cost Version 2. That offer was valid for a full year after Version 2 went on sale. It no longer applies.
Please note that support for Version 1 discs is no longer available. I have no access to any patches made for Version 1 discs and they are no longer available from the developer.
Version 2 of Volumes 1-3 was produced and marketed by Horizon Simulations. During the life of the product a small number of anomalies were identified whereby 'spikes' would suddenly appear as the user aircraft passed a certain co-ordinate. If the user had crash detection switched on then a 'crash' would occur. These spikes were stopped by the issue of small 'patch' files, to be placed in a 'live' scenery library higher in order than the actual scenery. Version 2, Volume 3 was found to have a rectangular patch of water South of Manchester Airport. This required a new photo tile which was issued with Version 3.
Version 3 of Volumes 1-3 was produced by Horizon Simulations and Playhorizon,(part of the Flightstore Group). Horizon Simulations had said at the outset of Version 2 that they would issue free extra 3D scenery/buildings and bridges to those moving from Version 1 to Version 2. With the release of these Volumes the extra 3D was included together with a number of High Resolution inserts of major towns and cities. Existing Registered Version 2 users were offered a nominal cost set of upgrade discs. This upgrade path was offered until sales of Version 2 were expended.
Version 3 Volumes 1-3 are the current release of Photo Scenery for England and Wales. Since release only one 'spike' has been found and reported. Interestingly it was in a 'No Fly' area reserved for military use. It existed in previous Volumes but had not been found. Users of this scenery obviously stick to open sky as do real pilots. A patch is available for this spike which works in Versions 2 and 3.
Volume 4 - Scotland: The Western Isles. Produced by Horizon Simulations and Playhorizon. This was the first Volume produced using 60cm base imagery. For the first time the Volume also included correctly aligned and terrain blended default airfields. There have been no anomalies found in this Volume and no patches issued.
Volume 5 - Scotland: Orkney & Shetland Isles. Produced by Horizon Simulations and Playsims, (previously Playhorizon). This scenery was issued with 60cm base photo imagery and corrected airfield. Some of the original release discs were found in certain circumstances to terminate installation missing out two files which corrected a height anomaly at North Ronaldsay and Scatsa. These two files have been made available as a patch. No other anomalies have been identified.
Volume 6 - Scotland: North. Developed by Playsims and Produced by Horizon Simulations. Issued with 60cm base photo imagery, aligned and blended terrain default airfields. No anomalies have been reported with this scenery since its release.
Volume 7 - Scotland: Central. Developed by Flightstore and Produced by Horizon Simulations. The newest release in the series. 60cm photo scenery, 5m terrain mesh, aligned and blended default airfields. It has been the longest scenery in production due to the difficulty in obtaining full photo coverage of the area. To achieve what has been done has meant many hours of stitching images, colour balancing within seasons and in some cases across the years. A problem with a section of terrain mesh was discovered after the product went to print. A patch is available to correct the problem.
Volume 8 - Scotland: South. Developed by Playsims and Produced by Horizon Simulations. 60cm photo scenery, 5m terrain mesh, aligned and blended default airfields. This is the Volume that handles the transition from the 1.2m photo scenery of England and Wales to the High Resolution 60cm Scotland.
The installer is designed to differentiate between those having England Volume 3 and those who do not in a 'standard configuration'. Different masking is required depending on other scenery default/photo. If you don't have a 'standard' configuration a set of manual install files are available on the root of disc 1.
Unusually two photo tiles in this volume seem to cause aircraft crashes though if you don't fly over them they appear perfectly normal scenery. Replacement photo tiles are available to patch this problem. Another small terrain anomaly has also been identified and has been patched. Total patches for this volume = 3.
Volume 9 - Ireland: East. Developed by Playsims and Produced by Horizon Simulations. This 1.2m photo scenery is married with a 10m terrain mesh. Also included are aligned and blended default airfields. Presently there are no know anomalies in this scenery.
Volume 10 - Ireland: West. Developed by Playsims and Produced by Horizon Simulations. This 1.2m photo scenery is married with a 10m terrain mesh. Also included are aligned and blended default airfields. Following initial release it was found that a corrupt file had been introduced covering the area of the Innish Islands. A patch has been produced which corrects this.
