Hello, I am wraping my head around exporting animated geo into usd. I'have animated points in geo, and every frame has milion polygons (and around 100mb) but only fraction of them moves. So playing back cache bgeo.sc is pretty slow. When I exported this into usd, but without flushing every frame's data, playback is really fast and whole animation weights fraction of the whole animation as single frames. I've found information that this is the way usd saving anim geo, it only saves information about points sthat changed some values. Unfortunately after about 40 frames of 69, my memory runs out and I have to split this anim into two usd files (both of them are about 150mb, so still huge advantage). I've found some info about stiching files, but when they are not single frames, usd stich rop node doesnt work. When I'am saving every frame on single frame after stiching it's size is just a sum of single frames, it doesnt work as saving without flushing. So is there way to stich those files, just as I would export all anim without flushing data?

- there is some Info on cgwiki - USD and big files
