How to use extracted shader?

[CarlLee]

I'm doing research on recreating golden cards from Hearthstone. I extracted some of the shaders Blizzard used to draw those cards, but it's in assembly, and there're some parts in random string, probably a type error.

Is there a way to use those shaders?

Posting an example

Which file is that specifically? I'm doing the same and am finding quickbms to do a better job with that sort of thing.

[CarlLee]

This was extracted from premiummatieral1.unity3d, it's called Card_UnlitScroll_2LayerDistortion_Premium.shader and there're a lot of shaders that's actually used by golden cards in shared0, shared1, shared2, too.

And the frame of normal card can be found in gameobject1.

I already figured out every file I need to recreate cards. I only need to know how to create hollow fonts like in the game and how to use those shaders. There're information about which card uses which shaders in cards0, cards1, cards2.

[CarlLee]

BTW, what bms script are you using? The script I found on Internet doesn't work

[ata4]

I'm not aware that it's possible to reverse shaders into more than this compiled text form. The Unity editor can load them directly from asset files, but this requires additional runtime type information that is not present in Heartstone's data files, as far as I know.

[CarlLee]

So this means it's not possible to use these shaders?

[CarlLee]

As test result, some of these shaders don't work properly after extraction even if exact same parameters are set.

Some parameters are missing in the script. I suppose those parameters are used in the compiled section of the script.

[ata4]

Hard to say, I haven't tried to re-use shader from compiled games in own projects yet. I guess the shaders requires a custom asset format (.shader?) that contain the required metadata in binary form, which can be loaded in the editor.

I'll close this issue for now, I'll reopen it once I found anything interesting that helps solve this problem.
