Ren'Py Ren'Py doesn't display live 2D motions

[PaPalon]

I want to use live 2D instead of putting video in the game. I followed the video below:

When I use Live2D samples in Ren'Py, everything works very well and there are no problems.
I made an animation myself and acted according to the video and the samples. When I define the character, it shows it, but when I add motion to it, it gives an error!
My codes:

image Silv = Live2D("Silv", default_fade=0.0, loop=True)

show Silv Scene1

And this the Error:

```
I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/script.rpy", line 42, in script
    show Silv Scene1
Exception: When showing Silv, Scene1 is not a known attribute.

Does anyone have any solution?

I know shit-all about Live 2D, but I just skimmed that video to where the ren'py code is added to look-see.

First obvious question is ... do you have a Scene1 motion in that motions folder?

Second question... Does the case match in your name of Scene1? Because Ren'py is case sensistive, so if you called attribute Scene1 but your actual motion file name is scene1, than that might be the error.

Only other thing I can think of is that using the name Scene1 is conflicting with predefined attributes and functions in Ren'py because "scene" is a core Ren'py statement for displayables. That's just a guess though.

Finally, and this is just my anal-retentive self coming out, but I prefer to define images using the full path and not just the folder. So "images/Silv" instead of just "Silv". I just started doing that a long time ago because there was some situations where Ren'py got confused over my declarations.

EDIT:

Just realized that you can place those Live 2D files anywhere. I was thrown when I saw the guy in that video put his in the image folder. So change question one to are your paths laid out properly? The Ren'py docs example shows the files in their own directory. Are your live 2D files in the root directory (ie: Game directory)? Maybe that's the issue? You could try putting the files in their own folder, say under "images" and then change the image declaration to this...

image Silv = Live2D("images/Silv", default_fade=0.0, loop=True)

Just reading the Ren'py docs further, try this...

show silv scene1

It appears that Ren'py forces the names to lowercase, so you need to use that in your show statement.

Thank you so much, the problem is solved!
I made a mistake at the beginning, I've chosen SDK unity instead of SDK. I fixed it then again don't work

At the first time changing to full path didn't help but after fixing the SDK,
Then this helped ☝

And this isn't True

It certainly is possible for case to be a problem - for operating systems that handle true case sensitivity vs faking it with metadata. Windows and *nix/*BSD act differently here, and python has it's own rules about dealing with filesystem name case.

Hi
I have another problem
Some motions don't work correctly
When I show the motion, it doesn't show some parts of the body (character) (in some it doesn't show the lips, in some it doesn't show the whole face, and in some, it doesn't show the hand)
But when I refresh the Renpy (by pressing Shift + R), everything is fixed in the current motion. I don't know where the problem is.

I still don't know anything specific about Live2D...

But what you are describing sounds like the sub-part images are not loaded.

You can hint to renpy what images it should load into the cache. So maybe you can do that for all the parts before you display the live2D?

.... oh, I just found that the function "cache_pin" was removed in Renpy7.

There's some explanation of Image prediction for Live2d here

.

And you could use the live2d logging to see if you can identify the problem?

You could also try changing the

configuration variable to maybe store more images?

I found a way
I've created a key for all parts(folders in Live2D) at the begining, for all animations and the problem solved
I think, Renpy has problem with empty parameters or parts (I mean parameters and parts without any animation key)
Thank you
