Crash when attempting to open Action Editor with Live2D characters.

[gengar1603]

When attempting to open the Action Editor via the Shift-P keystroke, an exception occurs as it tries to render the expressions of Live2D characters. The Action Editor opens fine if there are no characters on screen. Traceback provided below.

I'm sorry, but an uncaught exception occurred.

I was unable to reproduce that bug.

Please provide the codes that declare and show the image.

[gengar1603]

After further testing to narrow down the issue, I think i found the exact conditions.

1. there needs to be 2 or more Live2D objects on screen
2. one of then needs to be using an expression.

This is the script that can reproduce it... Let me know if you need the models themselves.

image ColleenUni = Live2D("Resources/ColleenUni/colleenuniform.model3.json", base=.5, loop=True, seamless=True, default_fade=0.6)
image Breath = Live2D("Resources/Breath/breath.model3.json", loop=True, base=.6, seamless=True, default_fade=0.5)

label start:

"test point before characters"
show ColleenUni m02
"test point with just 1 character"
show Breath m02 with dissolve
"test point with 2 characters - no expression"
show ColleenUni m02 exp_uni_reading
"test point with expression (crash)"
return

[gengar1603]

Have you been able to reproduce the problem?

[kyouryuukunn]

Sorry, I'm a bit busy, so it will take me a while to get started on this.

[kyouryuukunn]

I could reproduced this problem in v7.4.1.
But I found it wasn't reproduced in v7.5.0.
Could you just update Ren'py?

[gengar1603]

I can confirm that his is working properly with Ren'Py 8.5.0 Stable
