This video shows how you can use the new OBJCache syste, coming soon to MegaFiers, to import complex mesh animations from 3d packages such as Max and Maya into Unity. You can use the system to export complete particle system or fluid or smoke simulations or buildings being destroyed etc, In this video we use the SuperSpray particle system in 3DS Max to create a fluids animation, we then convert that to a Mesh using the Mesher option then export each frame to an OBJ file. MegaFiers then reads and optimizes those OBJ files and can create an optimized cache file which uses about 1/10th of the memory of the raw data and that file can be streamed from directly at run time.
You can export any kind of mesh animation as long as it can export to an OBJ file, so you could export particle systems, fluid or smoke, fracturing meshes etc
