Exception: Live2D shader has not been given uniform tex1 error

[Mole-chan]

Hello,
I'm trying to integrate a Live2D model into a short game but have been met with this error.

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/script.rpy", line 41, in script

  File "renpy/common/000window.rpy", line 69, in _window_show
    renpy.with_statement(trans)
Exception: Shader ('live2d.flip_texture', 'live2d.inverted_mask', 'renpy.geometry', 'renpy.texture') has not been given uniform tex1.

It seems to be rooted in a couple inverted masks that are used throughout the model, but the error itself gives no real clues on how to solve it.

For context, I am using the latest version of Ren'py and the latest version of the Live2D sdk. Config.gl2 has been set to true in options.rpy. All of the model's .json and texture files are present.

Any help would be appreciated, as I do hope to use Live2D more in the future and nipping this in the bud would be preferable.

Thank you.

Can you send me the model that's causing this problem, and the command you're using to show the Live2D displayable? What I'm seeing doesn't make a ton of sense, so I too would like to figure this one out.

Thank you for getting back to me! And glad it's not just me that's stumped.

The command to show the displayable is pretty standard, using the documentation as reference. Here it is with some additional surrounding code for context:

show screen FakePhone
show kiki idl
with pixellate
$play_music("audio/sleep.ogg")
k tired "-YAWN-"
k sad "I wonder if anyone is still awake. If I'm going to be up and miserable, I may as well have company…"

The displayable itself is defined as such:

image kiki = Live2D("images/kiki", height=.7, loop=True, nonexclusive=["blush","side_eye", "closed_eyes","slight_frown"], fade=True, default_fade=.4)

I've also attached the model, as requested. Please tell me if you'd like the original CMO3 file. I opted not to include it right away as it is quite large and I didn't want to burden you with it if it wouldn't be helpful.

I hope this additional context helps!

Just landed a fix for this. The fix will be in the next nightlies. Thanks for posting the data.

The problem seems to be caused by layers that both used a mask, and were used by a mask.

Awesome, thank you very much!

I'm glad my obscure issue could be of help in development.
