[Unity Modding] Image Anisotropic Reproduction help

[zigaudrey]

Hello!

I was working on a Python script that replace Sprites data with another for Unity games but Unity has another trick in its sleeve.

For those who use AssetStudio, you will extract sprites like this (from Dungeon Clawler 2024 Demo):

But with a tweak, I found out Unity uses more data to store RGBA32 sprites!

Unity uses an Anisotropic filter to enhance the quality. Something that is difficult to replicate with Python and every sprites doesn't follow the same rule! We have to follow them individually. Another example with Clawcula.

Interestingly enough, a partial replacement works and those which lack shearing, like the Logo, are easier to replace. Not every sprites use all "layers" which should make things easier.

What I replaced with:

And here is the original one:

Despise the flaw, it's sufficient replacement.

I was close to replace the sprites with Animal Crossing cub villagers without using Unity (after the Unity controversy, which lead me to mod Unity games with Python).

If you have information on reproducing correctly their Anisotropic effect, feel free to share!

Python Scripts:

• Unity Image Extractor: This extract all sprite data from resource files. Work on RGBA32 and RGB24. Don't forget to create a new folder, I don't know how to make the script allow you to choose one.

• Unity Image Replacer: This replace all sprites with those from the batch. Although it works for RGBA32 and RGB24, it works better for the latter.

• Unity Ano Simulate (Work in Progress): An attempt to simulate the Anisotropic effect for a bulk. Work best for no shear one.
