Hello,

I'm looking for a file format capable of storing an animated triangle mesh. More specifically, I have a different mesh (with completely different topology) for each frame, created from a particle-based fluid simulation using marching cubes, so skeletal animation isn't useful for me.

1. Is there some file format that can do that and is supported by Blender, 3ds Max etc.?
2. If not, is there a file format I could use to store the underlying particle data instead of the mesh?
