Here's the prototype Chapter 1 files for anyone who wants them: Enjoy
Now there are a few issues, mostly dealing with Boris's prototype mesh. It's there, but it seems to be part of the "map". So if anyone wants to take a try at extracting Boris from his room: I left a .fbx file in the folder. You then need to add textures. Boris uses misc_02_texture.png for his eyes and incision while using black and white textures for the rest of his body. Bendy uses monster_face_texture.png for his face and probably just black textures for the rest of his body. Have fun.
