Renpy Live2D Tutorial for Renpy 7.4.0

[MaxLib]

Hello!

Yes it can be a hardware incompatibility on my side, but I would emphasize I only have experienced that with renpy so far. Yes it is obvious this error does not affect all users fortunately. I am currently working with unity + live2d and the two are working perfectly together.

I recently learned that next renpy update is on the way which will fix bugs related to live2d.

I have already know how to use live2d in renpy all thanks to you, so keep those tutorials coming they are very helpful!

PSA for all NVIDIA graphics card users:

Renpy 7.4.4. was recently released this month that contains an update where Renpy has disabled the threaded optimization option for all NVIDIA graphic cards, including the older chipset models like the GTX 765m, etc. This would stop playing the Live2D animations completely when playing any Renpy Live2D game.

I highly recommend you stick with Renpy version 7.4.2 or earlier for those who want to stick with NVIDIA graphic card options.

On the other hand, for those with AMD graphic chipsets or Intel internal graphics cards, you should be fine.

Thank you for your understanding.

I don't believe this is the case. Threaded optimizations and Live2D have nothing to do with each other.

Hello everyone!) I installed Renpy Live2D Tutorial for Renpy 7.4.0. I just wanted to check (test) how this whole thing works. Video from YouTube: (https://www.youtube.com/watch?v=nbAgxfdukaY). Code in GiyHub: (https://github.com/galatra303/RenpyLive2DTutorial). I did everything as shown in the video and screenshots, but the python code does not work for some reason unknown to me. I'm new to scripting visual novels and maybe someone knows what the problem is here. Here's what's in the logs:

1. The tutorial was able to run on Ren'Py 7.4.2 (That is, the first
thing to do to run it is to download and install Ren'Py 7.4.2).

2. Then I forcibly enabled GL rendering in the settings menu: [Shift] + [G].

3. Next, I copied the "gui" folder from the game:
"the_question" to the folder ...\Live 2D Tutorial\game.

4. And in the folder "gui" I also copied from "the_question" copied two
files game_menu.png and main_menu.png (+ I changed the resolution
of these files to 1920 & 1080).

5. I had to download the BalooTamma2.ttf fonts and put them in a folder:
.../Live 2D Tutorial/game/gui/font/... And in the script gui.py (in "Fonts
and Font Size") specify the full paths to BalooTamma2.tff.

6. The options.rpy script should have: define config.gl2 = True.

All this helped me to launch the test tutorial "Live2D Tutorial",
unfortunately it didn't work on versions Ren'Py 8.1.0 & 8.2.1 anyway.

So maybe someone will need all this for a test run of the tutorial on Ren'Py 7.4.2.

And here's what he writes in the logs on the latest version of Ren'Py 8.2.1:

I'm sorry, but an uncaught exception occurred.

That is, again this is an uncaught exception...
