Lower Build Cost (Air)\common\units\equipment then in each text file change every line that says build_cost_ic to a different value. For the modules you'll do the same for the files in the modules folder within that folder.

Hey leion, how would I change your mod to lower the cost even more? (I WILL NOT publish the version I make.)

Could you please produce a mod to increase the cost of aircraft production? We want to prevent the game from becoming heavy in the second half of the game. Thank you in advance.

As long as it appears it needs one I do. Usually these work fine for major patch or two. I do make sure to check to see if the files have been updated every patch.

do you still update?

Am I the only one who crashes the game when trying to unload heavy fighters onto an airfield?

If bba = By Blood Alone the dlc, then yes. Otherwise idk what that means.

is it fine for bba then?

Technically, it is possible to make one with higher build costs. Unfortunately, I will not be the person to do so.

It's a shame there is only lower build cost and not higher, is it possible to make one? I mean it was great mod before(expensive air force), but it was abandoned and after the new dlc it doesn't work. There is too much planes in the late game.

Ah, I see. You were just offering some updated files for 1.12.3 since you were already working on it for another thing. Your kindness is appreciated.

They adjusted the plane costs, engines went a lot higher. Plus fixing naval bombers doing no damage.

I just went through redoing the 2/3 edits because I was going to merge it with another mod anyway - no worries if its not needed.

Update? It's already updated to 1.12.2. I'm unclear what's happening here. If you mean there needs to be an update for 1.12.3, that'll happen later today when I'm off work.

Hi, I was making other mods compatible when the update happened. Thought I'd quickly update yours as well.

Wasn't sure what the x_plane file did so that's untouched.

pls update

It's updated. While some of my mods don't require an update to work correctly in 1.10, this did. You can expect this to work if you have the newest version of the mod. If it doesn't auto update, try the direct download.

It works even outdated ?

Yup I miss that while flying over the description, usually features stands out of the text. ^^ Sorry to have bother you with my laziness. ^^

I do. It say's it reduces the cost of planes to 2/3rds of there original cost. Another way of putting it is that 1/3 of the original cost is gone. It's in sentence one under About Mod, which is in the mod description. I'm not sure how much clearer I could get.

You don't specify in your mods description how much you lowered the cost. Is it half the cost?

copying the link, removing the space put between mediafire and .com, then once downloaded, placing the zip file in Documents\Paradox Interactive\Hearts of Iron IV\mod and unzipping the file.

How would you download the file and add it into the game?

Not really Heimdall, American factorys of ww2 could spit out 650 bombers per month, which is alot by 1943

WTF Why ?
that Game have a total unrealistic Air Production and Air Spam problem. that Game need a Mod for a highter Build Air Cost's.

Thanks, I will update the descriptions now.

a little constructive criticism the word for the description should be a*ffected not effected, its an easy mistake to make but I have done enough science fairs to have the obscure distinction nailed down

Sorry for the extra work then. I wonder what I have thats messing with your files.

Just checked in the game with the mod on and in the base game files. I don't see any porblems and it's working correctly. I would suggest making sure no other mods affect the plane equipment files. Along with using the direct link if reinstalling it doesn't work.

Thanks for tell me. I'll look into it.

@leion247 I am not noticing a Airpower cost decrease. I am running the Building, Land and Naval ones of yours and they all have lower cost but the planes. Or is it just me? Just letting you know.
