add the rain in re2 ?

it's possible to add the rain in re2?

I was actually wondering the same thing.

Was there even any rainy sections in RE 2? The only thing I can think of is when the water is either dripping or the ones that are torrents of water in the sewers and since its all particle emitters all you would have to do is edit those sadly we don't have access to that kind of stuff afaik anyway.

Wish there was rain in RE2 Lol :/
and i also wish we can break the limits of modding ....

It may be possible with some trickery.
Firstly are there any animated textured portions in the game, like puddles?
Could introduce water like textures on the head and shoulders of the characters to simulate the rain crashes, bit like fire on enemies.
Resident evil 2 uses static tim overlays for the game, so you could mix some transparency with raindrops etc. Granted it wont be motional, but the high action of the characters movements + camera cuts you could fudge it

The only way I could think about going about it is this. (This is what I'd do to attempt it)

1: Change the water layer texture for the top of water to look rain animated
2: Place a thin layer of water into the room with the new rain animation.
3: Make the lighting look a bit more dreary.
4: Use the on fire animation for enemies to make a "rain drops on the shoulders" effect. (I don't know what u'd do for the player)
5: For the actual rain falling, I'm not sure, maybe if you get the smashed glass sprite and replace it with rain streaks, then place loads of them in a room high up and initiliaze the sprite animation on room start. Possible, but it would probably kill the game.

Well anyway, it's somehow possible, but you'd probably break loads of stuff attempting it.

there is the blood dripping in the licker hallway. perhaps make it rain blood?

Dooms Rain

I can imagine it being done just as Monkey & Evil said , it would take a long progress however
