Smaller Blood Pools (UE4SS)

Description

This mod significantly decreases the size of the dynamic animated blood pools and by extension, the animation is slowed. This uses UE4SS and a Lua script. No blueprints involved.

I did this primarily to teach myself how to make UE4SS script mods. Instead of creating new blueprint logic, I opted to create a custom Lua script for this since it is a simple-enough concept. Under the hood, the script hooks into the game, waits for the bloodpool game object to spawn and immediately manipulates its size. As a result, the animation changes dynamically as per the animation curve setup in the game's original blueprint (BP_NPCBloodPool).

Next, I'll try to influence the formation shape of the puddles using custom shader math and blueprint injection using UE4SS. Might take a while before I get to that point but I'm working on it; it's a learning experience! If you have any suggestions, feel free to leave it in the comments/posts section of this mod page.

Requirements

Requires UE4SS v3. 0. 1+ (UE4SS v3. 0. 1 Github download here) to inject since the bloodpooling system is controlled by dynamic blueprint variables during game runtime. I have tried without it (i.e: creating new material assets from scratch), but animation would not be possible due to the game's time reference being locked in the native BP_NPCBloodPool blueprint.

Installation Instructions

• []Download UE4SS from the official GitHub repository (see requirements link above)[/]

  []Extract and place UE4SS ZIP file contents directly into ~\Trepang2\CPPFPS\Binaries\Win64[/]

  []In ~\Trepang2\CPPFPS\Binaries\Win64\Mods, place the extracted contents of "Smaller Blood Pools (UE4SS)" (this mod's download file). You should have the following structure:[/]

~\Trepang2\CPPFPS\Binaries\Win64\Mods\BoomerPoolMod\Scripts\main.luaFinally, open "mods.txt" in ~\Trepang2\CPPFPS\Binaries\Win64\Mods, add the following line and save the file:

BoomerPoolMod : 1If you ever wish to disable it, simply set the value to '0'.

Notice

I used AI (Gemini) painstakingly to help teach myself how to do something like this. After reverse-engineering by myself for a long time and finally getting a grasp on the necessary properties and setup, I created and tweaked Lua code myself to reference the corresponding blueprint variables and manipulate their values. I am planning on creating my own dynamic(ish) blood system from scratch, but for now, I'll be experimenting with this as I learn more!
