ANZINS Terrain


This is my terrain shader mod for 1.92 Stable (DX11 only). Essentially it's an implementation of THIS idea and seeks to ameliorate, with varying ambition and success, a couple of gripes I have with the terrain in Arma;

Lack of Vibrancy: Between the haze and the washed out satellite textures I've always perceived a real disconnect between the sharp foreground (weapons, characters, vehicles, buildings & clutter) and limp background (everything else).

Lack of Texture: Dissatisfaction with the smooth, featureless & fuzzy appearance of terrain in the middle distance is well documented.

Additionally there are a couple of PBOs which are fundamental (yet optional) or complimentary to the above goals;

Less Haze (addons\haze.pbo): Pushes the atmospheric haze much farther out. I presume BI thought to soften the view distance block but to my mind the default haze hurts far more than it helps.

Colour Correction (addons\colour.pbo): With EvilOrgan's kind permission this addon enables his excellent EO_Real_3 preset by default. You probably have your own colour correction preferences so by all means delete this but maybe give it a try first as the mod was tuned for/with it (and PPFX Brightness/Contrast/Saturation at 110/110/70).

There may be some small improvement to concealment at distance but it wasn't a particular goal.

Probably won't be to everyone's taste, ultimately it's just a mathematical formula that treats each terrain pixel based on little more than its original colour so there's a limit to what it can achieve. It will make some things better and others worse - but hopefully more things better. I find the effect generally pleasing and it was fun to learn something about shaders (not to mention brush up on my high school algebra). I'd like to acknowledge material or moral assists by T_D, EvilOrgan and especially kju; beyond the many high-profile projects he's well-known for he's also always helping, advising and connecting modders and patiently sharing his vast knowledge of the game on numerous endeavours.

NOTE: As delivered, this addon will maintain your Shadows Distance (at ~200m). This is a mechanism to communicate real time FOV to the terrain shader (so it knows to lighten the terrain detail when it's viewed through high-powered optics).

To install ANZINS Terrain you should use modfolders to keep it seperate from the official game content to prevent issues.
With Arma 3 you can use different ways to set up your modfolders to use custom content you have downloaded.
Please visit the Arma 3 Mod install instructions page for more information about using custom mods and addons in Arma 3.

Included files:

- Moved EO_Real_3 preset to'
- Middle-distance noise is now blended more gradually with near detail textures.
- The influence of satmap colour-corrections on near detail textures is configurable per-terrain.
- The influence of the terrain normal on noise intensity is configurable per-terrain.
- Additional application of noise (sampled with a coarse UV) preset per-terrain;
- + First channel preset is linked to terrain colouration.
- + Second channel preset is linked to terrain gradient.
- + Third channel preset is linked to scope magnification.

- Minor tweak of Altis configuration.
- Add sub-mod to support Livonia;

- Minor tweak of Tanoa configuration.

- Blend away extreme satmap-shadows on approach.
- Terrain normal now influences detail intensity.
- Fix 'black square' noise when combined with PPFX (L_Suppress).

- Fixed banding in light pools on certain terrains.
- Texture blending; stronger detail.
- Texture blending; saturation control.

- Fixed issues with normals and parallax on near detail textures.
- Slightly softened detail blending with colour corrected satmap.
- Altered method of enabling post-processing colour corrections (EOReal3).
- Updated incidentally replaced data with that from the 1.92 release.
- Shader features should now never enable for an unconfigured terrain.
- ALTIS: Minimal tweaks to noise (lighter) and colour curve.
- STRATIS: New 2K noise textures (improves view through optics).
- MALDEN: New 2K noise textures. Terrain colour tweak (deeper).
- TANOA: Added initial configuration.
