I'm working my up through understanding all the non-standard binary formats in MPH. Models, textures, materials, palettes... There's a scattered but decent amount of info on these around the web, and I'm knowledgeable enough to fill in some blanks and make good progress. https://www.dropbox.com/s/rwcrl1rjhxlxkd7/blastcap_Anim.bin?dl=0 Now, I'm trying to unravel the mysteries of the animation format. So far, I've tentatively determined that this offset has the number of animations the file contains: Where do I go from here? I know that 3 is probably the number of animation blocks, and each block has a header indicating how big it is and/or how many frames it has. Then each frame has the data for which bone and its (relative? absolute?) transformation to take place on that frame. But I'm no good at looking at binary files and seeing these patterns.
