Summary

A small 2x1km, infantry-focused British Army training ground built with a strong emphasis on immersive detail, realism, and authenticity.

Official Workshop description

Longmoor is a recreation of the British Army's training area in Hampshire, built for Arma Reforger with an emphasis on authentic terrain, immersive environments, and realistic infantry combat. The Longmoor terrain contains 8 points of interest, with the key point being the central training town where most activity takes place. The town is split into two, with furnished modern buildings for COIN operations and dilapidated, barren buildings for more kinetic training. The town also features a historic railway line with large culvert access beneath the line, allowing people to pass through, including an enterable underground tunnel system with several entrances spread across the urban area. The surrounding terrain contains dense woodblocks with long internal sightlines, while also featuring large open areas with sparse cover and concealment. Micro terrain has been a major focus. You'll find lots of dips, depressions, berms, re-entrants, old platoon harbour and fighting areas hidden throughout the woods, and even the infamous "babyhead" tufts of grass that make almost any vehicle movement a nightmare, with one small slip enough to completely destroy your ankle. Good luck fighting on these! Civilians also share MOD land, so not too far from the training camp there's a small estate where military families and caretakers of the grounds typically live, complete with a local pub, shop, and football field. _____ Longmoor is my first release for Arma Reforger and a project I've built in my spare time around work, family life, and education. As a former British Army soldier who trained on these grounds, many locations have been recreated from personal experience alongside extensive reference material. If you want to get involved with myself and the community who brought you the Longmoor terrain, with no sign-up, zero commitment, and weekly operations in both Arma Reforger and Arma 3, then come over to discord.globalconflicts.net.

Added:
- Underground tunnel system spanning the full length of the main urban area. This has been teased since the very first Longmoor release.
The tunnel network is significantly larger and more expansive than its real-world counterpart, taking creative liberties where appropriate. It features long, winding passages connecting key locations, including a water treatment facility, reservoir, and maintenance room.
The tunnel system is currently missing its intended lighting. Unfortunately, I encountered a lighting bug just as I was finishing this part of the update. Rather than delay the release—and with the 1.7 navmesh issue making Longmoor effectively unplayable—I decided to release the tunnels without their final lighting. For now, they use the global environmental lighting, making them noticeably brighter than intended. This will be corrected in a future update once the issue has been resolved.
I also wanted to add water to the tunnels, but due to engine limitations, while I can place water beneath the terrain and it works in 90% of situations, the surface textures when looking down do not exist due to there being no terrain underneath to render against. As a result, I have opted to hold off on adding water until I can figure this out.
- New vegetation around the camp and other locations, including ivy growing along older buildings.
- Surface-level water added to the animal troughs at a barn to help resolve the underwater audio bug experienced by some players.
- Various environmental improvements throughout the map, including additional decals, kerbs, vegetation to break up sight lines, terrain levelling, sidewalk alignment, cattle grids to fields, and small prop placements using assets introduced in the 1.7 update.

Fixed:
- Broken navmesh caused by the 1.7 update. This resolves the major issues that made the map effectively unplayable.
- A new Header.conf file for the GM_Longmoor mission, as I believe the previous file was not loading correctly.
- Oversized vegetation issues. Longmoor is known for its unusually large ferns, and I originally scaled certain vegetation to better recreate this appearance. Unfortunately, this also scaled the wind simulation values, causing the plants to sway unrealistically—often to the point of distorting the model mesh. Besides looking unnatural, this frequently gave players the impression they were seeing movement.

Removed:
- Outside Terrain Tool mod. Apparently, once the terrain is released, only the Outside Terrain Core mod is needed as a dependency. This reduces the overall number of dependencies required for Longmoor.

Adjusted:
- Extended some walls in areas to fill in empty space and make better use of the environment. These also provide better hard cover across larger open areas while still making logical sense in their placement.
- Ground textures in some areas to improve blending.
- A door on the compound so it no longer opens into the ground.
