These are Alembic files, so you can use them in any 3D app that can open Alembic such as Cinema 4D, Maya, Houdini, Blender, Unreal and many many more. This also means you don’t have to deal with annoying cloth settings in Cinema 4D which take forever to cache. All the sims are cached and saved so you can just paste these into to your scene and you’re done! These flags do not loop, but they are very long at 480 frames each and 30 fps.
