I haven't had the time to test it, but my bet is you could build a string attribute on your copied geo to set the filepath and frame number using sprintf(), and query that with a Renderstate piped into your file texture in your material. I haven't done this with file textures, but it works great with geometry so I don't see why not.

Thanks, I also thinking about that and have tried replace randomly, but I think with that system its rewrite just
over everything with simple material and no timeshift, maybe if You have time make me sample, or any other example please, I am just lost
Thanks again
