ACES Simulated: New tonemap. New clouds: "old look clouds". (Thanks to @pvtTunt @ https://forums.bohemia.net/forums/topic/230063-how-to-make-old-lighting-configs-work-answered). directLightCoef is custom. Changes in apertureRatioMax, apertureRatioMin and maxAperture in HDRnewPars. Old vs ACES vs New The increase in brightness/saturation is due to an increase in the blacks and overall contrast which was too low. Although apparently less similar to the original ACES than before I think the overall tone and color scheme is more balanced. In game (post above) it still gives an ACES feel 😉👍. Here's the new params:

Arma 3 vs ACES Sim (new):

You need Event Handlers: https://community.bistudio.com/wiki/Arma_3:_Event_Handlers https://community.bistudio.com/wiki/Arma_3:_Mission_Event_Handlers https://community.bistudio.com/wiki/addEventHandler getIn or getInMan

Yep, wasn't easy here either. Lot's of trial and error and reading lots of stuff. Once I found that app (tonemapper) was smooth sailing though, so use it! Thanks. 🙂👍

I can't help you with this part. Maybe some math expert can. 2nd problem with proper indentation 😛 Just added removeEventHandler and params. _garrGRPA = [ (position structA), independent,["rhsgref_cdf_reg_squadleader","rhsgref_cdf_reg_machinegunner","rhsgref_cdf_reg_grenadier_rpg","rhsgref_cdf_reg_marksman","rhsgref_cdf_reg_specialist_aa"] ] call BIS_fnc_spawnGroup; [_garrGRPA, (position structA)] call BIS_fnc_taskDefend; { _x linkItem "rhs_1PN138"; _x setUnitPos "UP"; _x disableAI "PATH"; }forEach units _garrGRPA; (leader _garrGRPA) addWeaponGlobal "rhs_weap_rsp30_green"; _garrGRPA addEventHandler ["EnemyDetected", { params ["_group", "_newTarget"]; (leader _garrGRPA) forceWeaponFire ["rhs_weap_rsp30_green", "Single"]; _sposReinfGRPA = [(position structA), 100, 300] call BIS_fnc_findSafePos; _reinfGRPA = [_sposReinfGRPA, independent, (configfile >> "CfgGroups" >> "Indep" >> "rhsgref_faction_cdf_ground" >> "rhsgref_group_cdf_para_infantry" >> "rhsgref_group_cdf_para_infantry_squad")] call BIS_fnc_spawnGroup; _reinfGRPA deleteGroupWhenEmpty true; _group removeEventHandler [_thisEvent, _thisEventHandler]; }];

player setVariable ["MARTA_hide", _unknowngroups];

Take a look at this:

Update: New version "ACES Simulated" (update in OP). ACES tonemapping is a function on by itself within the ACES pipeline, which is currently the standard for film industry and available in modern game engines. Since the best (with more parameters like toe and shoulder) function we have is Hable's function, we tried to simulate ACES curve using it. This is very hard (impossible?) to do, but we can get some approximations. Credits to: Tizian Zeltner on GitHub for their tonemapper tool.

New tonemapping coming up:

Update: New version "Filmic" I never intended to update this but I was having problems with clipping in both brights/darks so I created this more balanced one while still offering quite more contrast compared to vanilla (ex in OP). I had to update the description at OP because I f* 'ed up. Oh, this version is more suited for Brightness 100 - Contrast 100. Oh, I found this great tool if you want to play around with tonemapping (EO, *wink*wink*): https://github.com/tizian/tonemapper Cheers! 😁 👍 Happy Holidays, Happy New Year and all that! PS. oldy41, I haven't forgotten about you! Trying to figure a way out for this.

No problem, and thank you. They all have LoadOrders (including Contact) so I made patches for all of them. Can be kept in folder even when (C)DLCs are unloaded. They should be good 👍 Thank you! I'm still undecided about Steam uploads, but I have massive respect for community veterans as yourself so I'll take your request into consideration.

Added them. Thank you. I added them to CAWorld since you didn't mention. Please test it out. I'm not sure CDLCs need LoadOrder on cfgPatches. (I also don't own CDLC's ).

Thank you, EO! Can you tell I don't own Contact? 😁🤫 Updated it. Tonemapping is the best, very powerful. Try it, you'll enjoy it. If you need help PM me.

HDR 2020 Description: Arma 3 has currently two types of tonemapping available: John Hable's Filmic curve (aka Uncharted 2 curve) and Reinhard's (remnants of Arma 2 or earlier). Tonemapping Curves have different operators that form each curve, some have more operators, some have less operators (there's plenty of Curves). BI albeit having started Arma 3 with Uncharted 2 Curve <src> <src> <src>, have since, updated it's operators values. This mod changes HDRnewPars and uses Hable's curve to change the look of Arma 3. There's 3 versions: Showcase - our first attempt at creating a heavily contrasted HDR image. Filmic - based of ACES with added contrast. ACES Simulated (recommended) - a recreation of the ACES curve using Hable's function. Supported Maps: Altis, Stratis, Malden, Tanoa, VR, any map inheriting from any of these, not from CAWorld Livonia (Contact DLC) (Thanks EO) Global Mobilization, S.O.G. Prairie Fire, CSLA Iron Curtain, Western Sahara and Spearhead 1944 maps (CDLCs) (Thanks EO) CUP Terrains CUP Terrains 2.0 Anizay Bozoum Dunes Global Ops Terrains Korsac Lybor Sa'hatra Sumava Thirsk (winter) Vanam Adding more maps: With your support I can easily add more maps. All I need is the map classname and the map classname it inherits from (usually CAWorld).

You'll only get lucky going on Discord and ask Dedmen or Killzone Kid for it for the next update (circa 6 months).
