The Assets folder typically contains all Assets for creating Characters, Environments, and FX - Meshes, like Materials, Textures, Blueprints, and other source files. Level Assets are not included here.
Each subfolder contains the appropriate source files for that Asset. For example, the Chr folder contains Character Asset subfolders, one per Character used. Each contains that Character's source Assets, that is, Blueprints, Skeletal Meshes, Skeletons, Animations, Materials, and so on.
The following list is how the Assets were categorized for the In-Camera VFX Production Test project, expanded to include a few Asset types that were not used in that project. It's unlikely for any given project to use all possible Asset types.
