- Tilt rotors of MV-22 are animated;
- New undercarriage animation mostly for all helicopters (except AH-64 and CH-3);
- New undercarriage animation system – it works with 3d scene objects animation. To make it work like you want you just need to give proper names for undercarriage parts, make required animations for them and change values in suspension config file for this helicopter;
- Some sort of suspension for AI controlled helicopters - wheels are align to ground surface, but if maximum or minimum limit of current gear is reached it doesn't works;
- Forest trees affected by fog;

Collisions

- Suspension works while landed on carrier;
- Additional type of collision points added – Stabilizer, Engine and Avionics. Cause corresponding damage;
- Additional points are added to helicopter objects;
- Position of collision points are calculating every frame, so collision of moving parts are more accurate;
- Collisions calculating are changed a bit – it’s more precise and do not cause false clashes, but on other hand it works worse with very small objects;
- Collision of moving points (rotor blades) do not stop model but create dynamic force in opposite direction;
- Collision points of main rotors are moving automatically from damaged blade section to previous;
- Damaged undercarriage will still work but has less effectiveness;
- Suspension dynamics added for all helicopters;
- Additional undercarriage point types are added for CH-47 and Ka-29;

- Interaction of helicopter with water are added;
- Missing collision objects are added for Mi-28, Ka-52, AH-64D, AH-64A, AH1-Z, AH1-W, AH1-T, OH-58. It means two things: were is will be less accidental crashes with AI controlled helicopters and it will be harder to shoot down these helis because hitting object became smaller (before it was huge bounding box, now it close to fuselage shape like for other helicopters);
****- Emergency landing counts if model on the ground and rotors not moving

Damage

- Tail rotor damage enabled;
- Severity of Main rotor/Tail rotor/Stabilizer/Main rotor blade damage is decreased, Engine damage – increased. It means you will not blow up because of minor damage;
- Delay of damage repairing while landed on allied keysite is fixed;
- Value of damage repairing delay is different every time;
- Damage can be taken both from land and other object collision. Amount of damage is depends on current velocity and angle to the surface;
- Hard landing can’t cause damage by itself (except undercarriage). If suspension will not able to reduce speed to zero it will be damaged and collision of fixed fuselage points will be calculated;
- Water random damage is added – than longer helicopter staying on water surface than more damage it gets (except CH-47 and CH-53). Engines will be damaged immediately in case of any engine collision with water;
*- Landing gears damage linked to global undercarriage damage;
*- Landing gears can be repaired at keysite;
*- Repairing cheat has usual delay when difficult is HARD;

SMOKES changes

"Wind affected" value became modifier

Yes, it looks similar in cockpit. but still can be switched off by Alt+R, without vertical synchronization it looks not so good at very low distance.

That, my friend, is sweet

So much better than the current blur animation, and an added level of detail that makes such a difference to the realism. It's small things like this I like to see getting added (although I'm sure it was no small amount of effort).

Does each model need changed individually?

I'm trying hard to make everything in code without models editing - it saves me a lot of time. It perfect works for most helis (except ah1z, on58 and helicopters with two rotors - swashplate works quite wrong), but this is minor bugs, visually barely noticeable.
Same is for damage - will try to make everything without changing any scenes.

Great work animating the blades!

Just my opinion, but I'm not a fan of the "flickering" rotor blades. The rotor at actual rotation speed moves too fast for the frame rate, so instead of seeing them rotate, the blades flicker in and out at random locations.

I think blurred blades with a somewhat slower rotation speed work much better and looks more like what rotors look like in real life (as opposed to in movies where they do flicker due to camera effects).

I agree about limitation of game frame rate (and digital cameras also), but I think it pointless to argue what is right and wrong - how looks blades rotating depends on rotor rpm, width of blades and most important - how good eyesight of the viewer. in real I see only mi-8 and mi-2, but quite often - several times per week at close range. for example mi-8 has 5 blades, rotor rpm is about 190 and I see blades like you said - flickering in and out at random locations, where is no any blurred shapes (like sectors or disc). of course In different conditions it can looks different - Kiowa Warrior has 4 blades and rotor rpm close to 400 (my cpu fan is slower)), maybe it will looks like semitransparent disc, I don't know.
anyway we will try to find compromise, or make it adjustable at least.

TADDAA! My mod is ready! =)

Weeehaaaa!

Says error opening ah-64 suspension

Read how to install CAREFULLY. I also had a problem with it.
It is amazing what he did thealx.Im shocked

I made a copy of \cohokum\3ddata\objects and replaced the old objects folder with the new one in the RAR file

then I made a copy of general and camo and replaced those 2 folder with the new ones in the RAR file, OR was I only supposed to take the items in the NEW general and camo and copy them into the OLD general and camo?

commom\ data\suspension is in a different place !

- Suspension configs moved to \common\data\suspension folder;

There is no common\data\suspension file/folder in the RAR file

There is also no common\data\suspension file/folder in my Razorworks folder

The suspension files are in Razorworks\common\data\dyn

What?:) what size you have ? 18 mb , and two folders common and cohokum inside.
just unpack all to your game folder.
If you have game in e:\eech unpack to e:\eech\
thats all! you do not have anything else to do
Unpack folders common and cohokum to your game dir

Yes unpack the 18MB RAR file to my cohokum folder and replace the items in objects and general and camo.

Not working.

Or like I asked above, do I not replace the old file and just put the new files in those folder?

I done this many times with other MODs so it's not my first time installing an EECH mod.

YOU SAID:

- Suspension configs moved to \common\data\suspension folder;

I don't have that folder in my C:Razorworks\common\data folder

This folder is in a zipped file.When you unpack zip file to the directory of the game.This will create the folder.

Btw, remember the MousewheelZoom work in this version!

Found errors-report here.
- I do not have  the cobra rotor animation)inside cockpit) outside is ok.EDIT:already have, probably due to the two folders.outdated
- when you select mi24 during the mission,and enter the cockpit two doors are open.

It's working now but it doesn't match up with the campaign.

On the old v.14 and v.15, you have green for Europe and Taiwan and desert camouflage for Yemen and Lebanon and Libya, etc.

Here on this new one, the MI-24 in the desert campaigns are gray/blue and one of the RED transport is Green.

Aside from that, I can't tell what else is changed.

Thanks for the mod but I'll go back to my old one.

I already do not have the patience,going sleep .you're right, do not install the biggest update for several years.

For others-in the first post, and in my posts is correct installation procedure.Everything works. new flight model  new damage system, and many others.

I've had a ton of fun trying this out. I've been cruising around in free flight just checking out all the new models/skins. The flight model alone has kept me occupied for a few hours. It's great, somehow it feels more fluid and less light and twitchy. Great Job!

Anyway, I finally started a campaign to see if anything changed. I noticed that the mission icons (the line with the X at the end) is no longer visible when you hover the mouse over enemy units. Therefore, when using the "campaign commander" modifier in the ini, missions cannot be deleted. Missions can still be added by left clicking on the enemy unit, but because the mission icon does not show up, they cannot be cancelled by right clicking. Any way to solve this?
