Back again with a new version of the mod! Tested with the latest version!
Just extract it in a clean version of the game. Must not have been patched before, but this download includes the autotranslator plugin with Gadriel's translation pre-applied.
So. I managed to reuse in-game animations! There is only one new card this time, that does not do anything interesting. I just made it because of TheUnsaid's request. This is a Bunnygirl copycat, empty and ready for modifications. She reuses all three of Bunnygirl's animation, as well as her model. She is fully compatible with the Squeezer edit menu. The only caveat is that I haven't found a way yet to put thumbnail for skills. BUT it is possible to have one squeezer use animations from different squeezers, and they all keep the same color scheme!
I also figured out how to fix the lags introduced by the mod, for good this time (hopefully)!
However, at the same, I changed a bit how the mod is loaded.
It is now possible to change the time it takes before loading by pressing F7, selecting "Options" in the topbar that appears, and modifying "Startup Delay Time". This is relevant because the mod needs to load when on the main menu screen. Your computer may load faster/slower than mine, so tweak this to your convenience.
In other news, I believe I now completely understand how to add custom animations/models into the game. The process feels convoluted, but not otherwise impossible. Haven't tried to do that for custom animations, but custom models I did with success.
... the only issue is I can't do art at all. But if anybody is up for it, I can help them! (I will post a more complete how to later)
