Adds textures/ with the crosshair PNG named by its ETC2 hash and a README covering install, naming and how to dump hashes for other textures. Nothing installs or loads it; copying into ~/.config/mocktail/textures is opt-in.

# Texture overrides
|
|
|
|
Optional PNGs you can drop into your own override directory. Nothing here is
|
|
installed or loaded automatically.
|
|
|
|
## Using one
|
|
|
|
Copy the file into the override directory, keeping its name:
|
|
|
|
```sh
|
|
mkdir -p ~/.config/mocktail/textures
|
|
cp textures/75dcd1166a6cbaa9.png ~/.config/mocktail/textures/
|
|
```
|
|
|
|
Restart the game. The log line `[vulkan] texture override loaded: <path>`
|
|
confirms it was picked up.
|
|
|
|
To remove it, delete the file again.
|
|
|
|
`MOCKTAIL_TEXTURE_OVERRIDE_DIR` points the lookup somewhere else.
|
|
|
|
## What is here
|
|
|
|
| File | Replaces |
|
|
| --- | --- |
|
|
| `75dcd1166a6cbaa9.png` | The in-game crosshair, as a thin dot-and-ticks reticle (128x128). |
|
|
|
|
## Naming
|
|
|
|
The file name is the 16 hex digit FNV-1a hash of the texture's level-0
|
|
compressed ETC2 bytes, which is what the override lookup keys on. A texture
|
|
Roblox re-encodes gets a new hash, so an override can stop matching after a
|
|
client update.
|
|
|
|
To find the hash of a texture you want to replace, set
|
|
`MOCKTAIL_TEXTURE_DUMP_DIR` to an empty directory and play until the texture
|
|
appears. Every uploaded texture is written there once as
|
|
`<hash>_<width>x<height>.png`. Rename the one you want to `<hash>.png` and put
|
|
it in the override directory.
|
|
|
|
Overrides are resampled to the size the game asked for, so the replacement does
|
|
not have to match the original's dimensions.
