Henry1887, I'm having an issue with the script to build asset, I'm getting an error "No AssetBundle been set for this build". I figured it has something to do with step 3, which I skipped because I don't understand what I'm supposed to do. What do you mean by "assign all Assets you added the same AssetBundle Label"?

Oh Yes im sorry i explained it a bit bad.

You have to select every asset you want to include individually and assign it a assetbundle name on the bottom right of the inspector

Ok, worked as expected now. Thank you.

Any chance you could update your plugin to allow overriding texture filtering ("Filter Mode" in Unity's inspector)? I'm thinking of making an "HD Interface" mod for the HUD and the buttons promt so it looks better when playing in higher screen resolution. Currently it seems the UI elements are all set to "Point (no filter)", so I'd like to be able to set the filtering to "Bilinear".

It should allow that out the box i think. My Plugin basically completely intercepts the AssetBundle Load call and if any of the override assetbundles contains that asset it will just load it from that assetbundle natively. It should respect any settings on that overriden asset.

mk40 also heres a little variation of my plugin that logs to the console when it hasnt found an override so you can see what the exact path is the game expects and also see what it loads:

Hmm, yeah I don't think it loads my textures actually. I'll check that in detail tomorrow, but if you want to take a look here's the file (only change the button icons for now).

Also, is this normal? Is it supposed to also create another AssetBundles archive?

Hmm yeah i just remembered that the assets i provided also included some that are originally not from an assetbundle but rather from "sharedassets0.assets" in your case for the ui textures.
Ill try to see if i can dynamically override those assets but i dont think theres an easy way.

 

[Henry1887]

Yea unfortunately i cant easily override those assets at runtime with my plugin. So youll have to limit yourself to those the game loads from its StreamingAssets Folder. Most if not all of the ui assets are not loaded from the StreamingAssets folder.

Well... to the trash goes my plan for this. That's really unfortunate.

So, from what you said, I presume you don't have any plan to make it works with the other assets files outside of the StreamingAssets folder then? I guess I could just replace the files directly from sharedassets0 since it's not encrypted, but... your plugin is a way more elegant way to do it without having to replace the orignal files.

There may be options for doing it, though they won't be as elegant as overriding Streamed Assets. Gimme a bit and I'll probably figure something out

 

[Henry1887]

mk40 I think i managed to do it as elegant as i can doing this dynamically.


I tried your Hd interface assetbundle with it and it made the textures a bit weird. Is it supposed to be like this or did i mess something up with my replacement logic?

 

[Henry1887]

its replacing it at least

 

[Henry1887]

could be a weird combined problem by my plugin and the game. Ill see if i can fix it

 

[Henry1887]

It breaks the Keyboard Textures but the Controller Textures look fine even though were only replacing the controller textures

 

[mk40]

The keyboard ones probably need to have their wrap mode changed. It's currently on "Repeat", changing it to "Clamp" may fix it.


Since the HD textures are 4 times the size of the original ones, some issue are to be expected though.
