I was looking for help reverse engineering .bsa and .an3 animation files from LEGO Star Wars The Complete Saga. For each .an3 file there is a corresponding .bsa file with the same name (Some .an3 files dont have corresponding .bsa files), .bsa files are considerably shorter than the .an3 files so they are probably not the actual animation but maybe metadata or something like that but the .an3 files are definetly the real animation and are much longer each .an3 starts with "4INA/ANI4" (Flipped for some reason, seems to stand for Animation 4 or something like that) that is then followed by possibly a header or some metadata after that there is the name of the animation in this case "dizzy" every single .an3 file ends with "C" followed by a long line of 3's "3333.33333.33" other than that I cant figure out much else. Help from anymore more experienced and better at this would be MUCH appreciated

Hello Friend. There Is A YouTube User Who Managed To Import The Animations, Edit them in Blender, and put them back into The Videogame from the same Program ;D

If You Look Closely At His Screen, you can see that he made a Script to be able to do it and Export it from Blender

Why do I feel you're missing some enthusiasm?

How about Lego Animation Modding Tool Tutorial? You might start with exporting a skeleton from .ghg in Noesis, see around 7:43

(But I feel the python stuff (see 1:08) might be too complex for 3D beginners.)

I dont see anything related to blender anywhere in the vid and I've checked multiple times so the person might have been wrong. But I will look into his other Java scripts
